I've tried Michelin PP 2CT's, a Power Pure, Metzler K3's and now Dunlop Q2's. I am most concerned with how a tire does on damp roads because it's foggy all summer here and the roads are wet under the trees in the morning.

The 2CT tire is great in that situation and now I found this morning that the Q2 is also great because I was going around a corner at 7am pretty leaned over and the rear started gliding out. The great thing was it was completely gradual and controllable, no highside tendancy at all, just a smooth breaking loose.

They must be using the silica in them as Michelin is. Next month they get a work out at Laguna Seca on the last track day of the year. If I live through that, I'll post the results and some video including closeups of the tires.

I love the look of a tire that has had 180 hp thrown at it.

A had a very unsettled moment on very cold Q2 tires - I was suddenly reaching to get my knee down to try and save a low side


it was surprisingly predicatable and
leter in the day as the sun warmed the tarmac they were again awesome
I am now reassured by your comments that they also work well in the rain..

send us pics of the tires after a great track day and 180hp ...

I run a trackday provider in Colorado and we had Jason DiSalvo out for one of our events this year. He rode a 1098 R steetbike with Q2 tires on it for the whole day, and turned some 1:48 laps (for reference the track record on a bike is 1:44, so he was moving right along).

All of this is by way of saying that I think you're going to enjoy the Q2's on the racetrack.

Ran a set for the first time this past weekend at NJMSP (R6), have been on various Pirelli tires for the last 6+ years. After a couple small slides when the tires were brand new and scrubbing in I had zero problems. Started out at 29R/30F cold and tire wear was looking real good, for $190 a set shipped I can't complain, have a set sitting in the basement for the RSV4 when the stock tires wear out.

Where have you found them for $190 a set?
I've run them CMP and was a little nervous at first, but they worked great. It was the first time running a street tire on the track and the first outing on the bike. Both worked awesome.

Not in the rain! On a dampish foggy morning! In fact, the guy I bought them from races (mostly slicks) and said he thought they were NOT good in the rain.

Pics will be posted if I can just remember to take the good camera and not the cell phone.

Sorry to resurrect this one but I'm on the hunt for new tires and the Q2's look to fit the bill.

The question is, how did they fare on track? I usually run about 3-4 days on a set before I switch them out for the reason that new tires cost less than crashing. Just curious to see if I should expect the same out of the Q2's.

Q2's and the Bridgestone BT-016's replaced by the S20 are all in the same boat.
I really like the BT-003RS but they were not on sale last time so I went with the Q2's.

Just make sure and warm them up good or WHOOPS!

Currently running the BT-003RS and I like them but wanted to try the Q2's. Of course, I could get BT-003 for about $320 shipped. That extra $40 might be worth it to get something I am familiar with.

I gave half a thought to run the Q2's on the 1st session since the track will be cold, they'll warm up much quicker than the slicks. Since I have 2 sets of wheels I could entertain the thought but then again, nahhhh, too anxious to get some time on my very first set of slicks.

I've run both tires before. I prefer the BT-003RS but they are both good. The Q2 are just slick until I get a couple of laps into it. I can just get them to slip pretty easy with out even pushing to hard. Once warmed up really good I like em.

CBar on the forum lost his Bimota on them. I think he got a bad set. He was running maybe 1:50 @ MSR Cresson which isn't really pushing them to hard.
They looked like they got over heated. Which if they were made correctly then they never should have been to hot.

They would indeed alter the geometry. I know this is from a 2010 test and probably posted here before but it relates directly to the quote above. Looks like the Q2s will lower the rear and raise the front over what the BT-003 and the Pirelli SC would do.

q2s 1991 mm circ = 633.77 mm dia (24.9514")
diablo 2025 mm circ = 644.59 mm dia(25.376")

so q2 is approx 11mm smaller in dia than the diablo (3/8")

THeoretically than you'd need to raise the rear end 11mm to compensate for the dia. diff? Or am I totally missing something?

The pragmatic answer is "only if you can feel it" and it feels worse. You'd want to include the front in the number crunching I would think.

You should only have to raise the rear 5.5mm because the the over all is 11mm larger. To simplify it we are only concerned with how much the Q2 actually lowered the bike. It may be more complicated then I'm thinking. Somebody please correct me if I'm wrong.

Ride height is affected by the radius, not the diameter so it would be 5.5mm.

zvez
04-04-2012, 04:51 PM
Ahh good point, you guys are right, the wheel is on an axle so only half would count. Math was never my strongpoint! ;)

So 5.5 mm for my limited riding ability and track inexperience won't be a huge deal for me I don't think. but I'll let Mike thermosman set it up.

Dude, you win the prize for best post of the day.

What's interesting is, if that Pirelli table is correct my measurement of the DRC rear was off by about 10-15mm.

igotyofire
04-04-2012, 08:24 PM
Now common sense tells me that the front forks are are off-setted (Rake angle) so for example raising them 2mm isn't necessarily the same as lowering the overall front by 2mm so one will need to find a proper measure point even though we are talking about mm here. I just did the math myself & realize it was all based on the 190/50. I will redo it now.

120/70/17 front Q2 = 604.52mm (23.8")
120/70/17 Supercorsa/DRC = 600mm

190/55/17 Rear Q2 = 642.62mm (25.3")
190/55/17 Rear SC = 652mm
190/55/17 Rear DRC = 642mm

So, the change from the DRC to the Q2 is 5mm at the front and the change from the Q2 to the SC is +5 Fr/-9.4 rear. I would definitely think the switch from the SC to the Q2 would make a geometry change worthwhile. I ran 2 sets of Q2s on my 2010 and had the rear shock length set at 313mm and it worked well, but I also run ~40mm front sag.

In light of this additional info, I will probably increase the rear shock length to adjust for the shorter DRC rear.

Per Tony Foale's calculator:

Rake Angle = 25 degrees
Yolk offset = 30mm
Tire rolling radius = 300mm = ground trail 106.79mm = real trail 96.78
Tire rolling radius = 302.3mm = ground trail 107.86mm = real trail 97.75

I don't think I understand what he means by this - anyone understand it well enough to explain?


Trail
The primary function of trail is to build in a certain amount of steering stability, and it also is of
great importance to the lean-in phase when cornering. We can see that both front and rear tyres
contact the ground behind the point where the steering axis meets it, this gives rise to a castor
(self-centering) effect on both wheels. The linear measurement of this castor along the ground
(steering axis to centre of contact patch) is usually called the trail.
However, it would be more logical to use the distance between the ground contact patch and the
steering axis as measured at right angles to that axis. This is the distance that creates a torque
about the steering axis from any forces at the tyre, to distinguish between these two trail
definitions, when necessary, I suggest that we call them ground trail and real trail. Real trail is
approximately 90% of the ground trail for bikes with a normal rake angle, and is equal to the
ground trail for zero rake. Compare figs. 3.1 and 3.2 to see the difference. The importance of
this distinction will become clear later in this chapter.

190/55/17 Rear SC = 652mm
190/55/17 Rear DRC = 642mm

In light of this additional info, I will probably increase the rear shock length to adjust for the shorter DRC rear.

as noted above though to run original setting OEM specifications we need to cut each of those values in half since the axle is mounted in the center of the tire, so the value to be concerned with is the radius of the tire not the diameter. So if making this change we +5mm in the rear ride height & lower 2mm in the front. If i am wrong please correct me, hehe

http://www.tonyfoale.com/book/Geom.PDF

I found this to be a bit more clear as to what increasing the amount of trail will do:

Motorcycle trail

The distance on the ground between a straight line drawn through the center of the front wheel spindle and a line drawn through the center of the headstock axis. The greater the trail distance, then the greated the straight line stability but the harder it is to make the bike corner.

Taken from: http://bikearama.com/theory/motorcycle-rake-trail-explained/

So, increasing trail increases stability but makes the bike a bit "heavier" to steer. I doubt that in my case I would truly notice. In fact, as a test of my skill I would like to run a session with the Bridgestones, then swap over to the Dunlops and see if I even notice the difference.

I talked to Chris at motogp werks in OC & to Lindemann Engineering...both of them seem un interested in in dialing in the bikes geometry due to different tire sizes. I explained I switched from pirellis sized tire(metzler) to the Dunlops & Pretty got the impression I shouldn't bother them with it & the mm we are talking about here are only felt by high level racers at the pro level....I tried to loosen the triples myself but couldn't break them loose witht he front fairing still on the bike. Felt like my T wrench was going to snap. Eh still waiting for my bike back since 4/18...its been gone for warranty work & seems like dealer is too busy with other non warranty work.

Good afternoon Kevin,
Thank you for contacting Dunlop Motorcycle.
The SportSmart will not be brought into the USA or Canada.
The SportSmart is comparable to Q2. Both products were developed for the Sportbike segment. Both Q2 and SportSmart are outstanding when used on the track. Q2 was designed for US roads while SportSmart was designed for European roads. There is quite a big difference in road infrastructure and weather, which directly affects motorcycle treadwear.
In Europe, the landscape between regions just a few kilometers apart can be completely different. From narrow and twisty roads to cities mainly consisting of roundabouts. Roundabouts replace our traditional four-way signal intersections. Commuters in Europe subject their tires to more cornering forces while US roads subject tires to more braking and acceleration forces (stop and go).
On average Europe has 20-30% more rain days than the US. Also, gas prices in Europe are 2x higher than US. So Europeans tend to use motorcycles more for commuting. With this being said, the SportSmart needed to focus on European commuters with their wet twisty roads as well as track-day enthusiasts.

That's pretty funny. The same woman sent me the exact same form letter when I asked why we can't get the SS's. It's an absolutely ridiculous response, isn't it?

I've been able to pick up a few take-off sets of the SportSmarts and hope to somehow be able to get them in the future. Such a nice tire. Nicer than the Q2s which indeed are no slouches.

That response from Dunlop was just stupid!

Europe is one fucking big place... As is USA. Both cuntries (Not a typo :D ) have such diverse temperature extremes and road extremes that it is just dumb to say that one tire is working better in one region compared to another, based on her justifications.

I can understand a different tire for Spain and the UK, as one is hot and dry with good road surfaces and one colder and wetter and lots of shit B roads..... but to say Europe hyper-sport riders accelerate slower and brake less hard than their US mates is just ignorant. As is to suggest that having more roundabouts in European cities compared to traffic lights in the USA is why they have a different tire design on a hypersports road legal track tire for superbikes!

Then to say that Euros commute more so such a tire focuses on commuting, wet twisties and track days... Doh! Seems to me the writer was a Bi-polar psychotic liar with a penchant for braking wind and verbal diarrhoea

Interesting thing I noticed yesterday....after the trackday was over me and my buddy loaded our bikes into my truck. I'm on Q2, he's on BT-003. Both tires are 180/55/17. However it was his 1st trackday (C group) and he was able to get all the way to the edge of the tire on the rear, which for me was a surprise. My rear tire still had a 1/4 inch or so til the edge. I'm in B group. The shape of the tire was quite a bit different. My Q2's more round, his BT003s more triangular. I think I'm gonna try the Bridgestones next time as I felt the bike didn't want to transition from left to right fast enough. Felt like I had to muscle it around the flop over quickly. Didn't think much of it til I saw how much rounder the tire was compared to the BT.

Anybody else on Q2s notice a slower turn in?

Hey John. Q2s to me are not a quick turning tire. I think they're neutral steering, planted and compliant, but not real nimble.

Yea if I use a 190+ tire on a 5.5 inch rim i don't use all the tire. On the V4, I almost always run to the edge on any tire... long as its a 190 only, on a 195 I don't use all the tire

I think the Q2 has a bigger contact patch on the sides than the BT-003 - I have used both DOT race and RS version and they both seem to turn faster than the Q2 which can be an advantage on a slower turning bike, but to me the RS version does not have the out right grip of the Q2, and the DOT version is definitely a step below the GPA211s

I just changed to the Q2s from the stock Supercorsas. Turn in felt similar. But even of the Q2s are slower than some other tires the TUONO still turns quite fast, so its never a problem.

On the road I'm getting to the edge of the Q2s. But I couldn't get to the edge of the Pilot Pure 195/55's on nh RSV Factory till I did a track day. And even then it was only just to the edge & lightly scuffed

Not all balled up on the edge like the Q2 s were on the road.

I have two new sets of GPA's for sale at the same price as Q2 in the Other stuff for sale section if anyone is interested. A much better tire for track days or racing than the Q2. The Q is a better street tire which is it's intended use. At big Willow the GPA's are capable of four to five seconds a lap quicker than the Q's, If you have the talent!

In case this horse was not yet dead enough, I just did a trackday on a set of Q2's. In short, they made me miss the Bridgestone BT003's. The bike felt slower to transition just as noted above. Also, the front felt a little greasy at times and wanted to plow through the turns. Granted, it was a hot day but neither the Bridgestones nor the stock Pirelli's gave me that kind of feedback from the front.

When a street tire gets too hot you will get a greasy feeling from the front and rear... 100+ degree surface temps along with the roughness of the track surface is not a good fit for these type of tires

Amen to that :)

It was a good learning experience and the bike never felt out of control, but it would have been cheaper to get a new set of Pirelli's and run them three days instead of cooking these Q2's in one day.

well even a HP street tire such as the supracorsa sc or the metelzer racetec will not give up as easy but because they are street tires and have a higher content of silica and other materials to make the heat up faster, they will cycle up and down faster on the track than a Race tire. You'd came out better buying a set of slicks and just taking them off after your TD

Yeah I agree with that. But I guess the challenge for many people is thay have to ride to the track day as they dont always have a trailer etc.

What PSI were you running them at?

What PSI were you running them at?

Cold: 29 rear and 31 front

Hot: 34 rear and 35 front

Hot pressure was measured ASAP after getting back to the pits as I don't run warmers. The pressure gain from cold to hot is right in the 4-7 PSI range.

Hot pressures don't matter much on street tires, if you are fast enough you'd want to get more traction and stability from a race tire

Dunlop recommends 32/32 with Q2's and say that anything lower will just degrade the longevity while not helping much with grip. I tend to run them at 30/30 myself and am somewhat please with them for the price. There are nowhere near an NTec tire for sure, but they also don't cost anywhere near as much.

For the record, I have run them on both my GSXR 1000 and Edwards RSV R....

True - it is said in the most capable hands the Q2 is only 6 seconds slower than a DOT race tire...
This means that it is great potential, but I'm sure that track abuse kills the longevity and when it gets too hot it has a slippery greasy feeling...

Well, if it means anything, at VIR South I ran a best in the 1:14's on my ZX6R with slicks. On my Gix 1000, I ran a best of............ 1:14's on Q2's. They were limiting my corner speed and drive out of the corners somewhat, but where do you accept the trade off? Cost? On a set of NTek I may have pulled 2 seconds off that, MAYBE 3. Not sure, but I know they would have cost me a whole lot more too..

All I am trying to say is that in capable hands, the Q2 is a decent tire that will cost you much less than DOT's. With a average rider that uses the same bike for street and track, I consider this a very good trade off. For a bike that is a dedicated track bike, I would prefer a DOT tire though. Course, I am the same guy that has run circles around people at VIR North with a Futura with hard bags attached as well, running Angel ST's... That's just too much fun sometimes!

Q2's are ok for the road but nowhere near the best...very slow to turn compared to rivals and even the basic D209 Quali is a nicer tyre.
I've run the D211 gp's for a while and they suit most circumstances but are difficult to dial in for all bikes.
Bt003rs are great fun and work great on most bikes but are overkill on the road.
Best allrounders are BT S20, Sportsmart, Metz M5's or old faithful Mich PP2CT which are my current fav.

Keep in mind the Dunlop Q2s in the USA are NOT the same as the Qualifier IIs in Europe. Completely different tires guys.

The USA Q2s are essentially one step down from purely track tires, and Dunlops highest spec dedicated street tire in the US. Although I've heard about a new 211 based street/track tire in the US coming?..

When warmed up; the Q2s do ok in the rain. If they do slide out, the slides are very predictable and manageable. Ran them at a VIR in a complete downpour, slow pace, and they didn't slip once.

It rains so little here in So Cal but what you may have experienced is that when it first rains, the roads are slick as ice because of the fluids cars and trucks have leaked on to the roads especially at stop lights. If enough rain falls it washes it away- but no tires work well when there are fluids on the road. It is really bad here when it first starts raining and I find it best to stay in the tire tracks of the cars and not in the middle of the lanes where the fluids are. I have been in the mountains on Q2's when it was raining and they worked just fine until we got down to the city, and had similar slick areas at stop lights just like you mentioned.

True about the cold tire statement. Nonetheless. Of All the tires I've ridden on the street (pilot power, pilot power 2ct, power pro, diablo, diablo Rosso, Rosso II, diablo Corsa, and stock d207's) none scared me like those q2s. Awesome grip in the dry though. One of the best there;)
