bedders u r starting to piss me of with how u speak to people.

Rs Adams RS holds 60. So do the other 7 RS's in the group of 3 villages we all live in. 7 Rs's all different years all with crap speedos? Nah. These RS's can push 70 redline. THEY DO HOLD 60, COME AND HAVE A LOOK AND SEE FOR YOURSELF :mad:

I've clocked my RS with several cars, and bikes, and my speedo is pretty close. its actually more accurate than most other sport bikes, that barely show 5mph increments on the dial, its just that a few mph makes a big difference on the RS-50.
Anyway, Without being tucked in, I hit an indicated 75mph yesterday. That was pushing in the red with 13/43 gears, I'm still braking in my 75cc cylinder, so I didn't want to push it too hard, but its making usable power past 11,000 rpm. I should also mention that I still have the stock clutch, and that it was slipping a bit in 5-6th gear. This thing is fun to ride now! Feels like a different bike. I almost F**ked up, running into a off-camber 90 corner, I didn't realize that I was doing almost 70mph, and had to drag the brakes late into the corner, to scrub-off some speed. I never thought I would get into trouble like that on an RS-50. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/embarassed.gif ALT=":o">

My Parts:

TP 75cc,
Mikuni 24mm,
Arrow exhaust,
carbon reeds,
uni pod-filter.

lol rob never thaught ud have to do that on a rs-50 :)

06-05-2002, 08:32 AM
I just sold my RS50 through European Cycle, but before I did I would get it to 84mph. That was with the 75cc top end and 14/43 gearing and 12,000 RPM.

It's all in the gearing, but you need decent power to get you there. I needed a good straight to allow the motor to pull to that speed. The more power you have, the higher you can gear it.

06-05-2002, 09:18 AM
to be truth full i would prefer faster acelleration and some high top speed but not like 70-80 i would like a fast take off wit bout 50-60 tope end

06-05-2002, 04:37 PM
I've checked out my speedo with cars, and my speedometer isn't off. 2001 rs50.

06-06-2002, 06:52 AM

dont 6 points mean youve lost your license? Have you actually got the points on your license. You have had it harsh mate cos i had no L plates front and rear, illigal number plate and thats just the visible illigal stuff.

But you are actually quite lucky only getting 3 points for doing double the speed limit, im not really in the position to lecture you. Has it made you slow down, i wouldnt dream of speeding now unless im on an A or an M road.

Good luck to you gettin any sort of decent car or bike when your 17 wiv those points. :)

youre allowed up to 12 points on your provisional untill you pass youre test then youre only allowed 6points for 2 years then its 12 again after that i asked the police cos i thought i was f@cked after 6 and i havent slow down atall im just more on the look out for cops hidden in they sneaky little hiding places.

06-08-2002, 10:44 AM
yeh my illigal plate is the second one just real small. So do the points that you got on your provisional carry over to your full license when you get it? Cos if you got 6 then they ytransfer over you would already have a lost license if you get wot i mean.

Key Walshe
06-08-2002, 01:48 PM
If you have a provisional with 6 points or more on it you can still get a full license....... BUT as soon as you get 1 more point you will be banned!!! Can't wait till April next year when I'm back down to 3 points hehe :D

06-09-2002, 12:58 AM
This Has gone WAY WAY off the topic Please continue with the acutall post

you think @#%$ your @#%$ that engine


06-17-2002, 06:20 AM
If you get 6 points on your full licence you aint banned. Your licence is down graded to a provisional & you have to resit your theory & practical tests.

06-17-2002, 07:32 AM
i have got a full arrow exhaust and a special filter that i can tell u about. it is @#%$ hot of the mark and does 100+ top end. i have fitted a full NOS power kit for a RS 250 and it is dangerous if not used properly!! in the instructions it says if all else fails hold the @#%$ on and hope the 20LB bottle of rocket fuel runs out soon.

06-17-2002, 07:37 AM
you lot are pussies you should get a full NOS system and hit the 100mph+ mark. go on this website they can sort u out www.nosnitrous.com

good luck

its some hot stuff

06-17-2002, 10:27 AM
how long does one of these 20lb bottles last

then what happens to your bike afterwards?

While we had no speedo on our race RS we did have a good tach and that let us hit about 13,500 rpm with 14:41 gearing and 120 rear tire on a modded TP cylinder (75cc) with modded Arrow exhaust (20mm removed from header pipe) and custom PVL ignition set up. This was running a 24mm Mikuni jetted 190 main and 17.5 pilot with custom emulsion tube and needle attached to the stock (but modified) airbox and running premix of Castrol A747 at 28:1. This should equate to about 91-93 mph. Our bike was also 60 lbs lighter than a stock street RS.

07-23-2002, 12:00 PM
I currently have:

Malossi 74cc kit
Dellorto 18mm (26 mm Mikuni or Dellorto *)
Topperformances clutch
Jolly Moto exhaust ;P
cheap metal filter (k&n filter *)
14/47 (14/43 or 14/41 *)

I'm still using my standard crankshaft, if I'm riding with this setup much longer I have a big problem, but im saving money for a doppler racing extreme crankshaft.

(*) = coming soon

I don't know the top speed exactly (I'm still waiting for some parts to repair my speedo) but its about 120/125 km/h so about 80 mph

(micah.....what did you remove from the stock rs to make it lighter?)

07-23-2002, 08:15 PM
If you go to the apriliaforum homepage and click on the "older Aprilia's you may have missed" link at the bottom, you will find a collection of pictures of Micah's lightweight RS50. The bike is the third picture down on the right side. All of the street hardware was removed(lights, tun signals, etc.). I believe they removed the battery. From past posts, they indicated that the biggest weight savings came from changing to the RS250 racing tail from the heavy stock tail with the passenger seat. Of course, many of the race part upgrades also shave weight from the bike.

Ride safe!

07-25-2002, 01:26 PM
What mine sit's at 70 mph and when and when i am pushing it. it does 80 mph and i have just changed the Sprockets.

07-25-2002, 03:35 PM
My RS is partly de-restricted through the dealer before i bought it. It will touch 65mph but wont go any higher, well, it might do, but im too afraid!! Dont ask how it gets to 65 (coz i dont know!!)

08-19-2002, 09:58 PM
heh, mine hits 65mph bone stock.

08-23-2002, 11:06 AM
How the bloody hell do you manage that?! It must be de-restricted.


08-24-2002, 06:20 AM
in america the rs has no restrictions, so bone stock is the same as a derestricted uk rs,

my bike- 73.5cc, 21mm mallossi, gianelli pipe, 14-44 sprokets

lol yeh could i jus say my exhaust has not been derestriced but it has no from cone and no sgns of one been there it can get 55mphis this full exhaust de-res. or jus front cone took out?

10-13-2002, 03:45 PM
Same with mine, mines a 2002 sbk rep and it does 55mph on flat 62ish tops down hill so i think its only the exhaust de-restricted.

10-14-2002, 06:51 PM
I changed only the exhaust, and i am 92kph (don't know in mph) My exhaust is a Technigas. My bike is a 2002 RS50 GP-1.

What can i change if i want to be faster (about 100 / 110 kph) ?

(PS: i would rather keep my low fuel consumption)

10-30-2002, 04:44 PM
hmmmmmm......I get about 115mph out of my bike.....the RS125 that is :D .

Of the RS50 I had i coundt take anymore than 40mph becouse it was restricted and new.

*now thinking of buying RS250, but theinsurance is too expensive, shame, oh yeah also I need a full license*

11-04-2002, 04:56 PM
Yeh my mate said his RS125 did 120mph... drove behind him in my car, we stoped and he said he hit 118 but my speedo didnt budge over 95mph, sorry to say but your clocks way out :)

11-11-2002, 10:42 AM
thats way more than 10% out u sure he ainnt bsing or ur car is out too

his may be 10% >>>> forward accurate so really he was doing 108mph and urs may be 10% <<<< behind so u were realy doing 103.5mph :S

11-14-2002, 03:57 PM
how do i fit a rs 250 racing tail on my rs50?

12-14-2002, 01:50 PM

looks dumb when a cyclists passes me when I'm fully tucked in and ready to go 150mph =)

So really most of you dont have an RS 50 that can go past 60 mph cause you have all modded em to be RS 70's etc

12-26-2002, 09:32 AM
ive gone past 60 on my stocker! 71mph to be exact n with a 10% inaccuracy either way its aroung either 66mph or 78mph

my next step is to fit a 21mm carb onto the stock cylinder n exhaust, i wonder if this will work on n what jetting will i need for the UK

About 70mph down a steep hill now.

believe it or not this bloke got erm 114mph out of his rs 50 yes u herd 50cc not 70 like u TP AND other modded phsycos. this was with a speed trap and a police radar gun at a dragstrip at a charity show. anyway mods are:

Well its aint quite an rs50 its a honda rs125 gp chassis the only rs50 part is erm the minarreli am6 engine.lol, anyway this race bike has only a race rear seat in the way of farings! then the engine lasts 10 hours so it can endure in the 6 hour races. it is so tuned it revs to erm 18,000rpm and ported and reangled to only work between 13000 and 18000rpm below that u may aswel walk the race. u should hear this thing go its legendary. he has a specially made crank a custom made piston that took 10 hours of CNC work on it rod and bearings are all super duper, clutch from minarelly and it has no flywheel dont ask cus i dunno and an igniton that is so advanced its prolly contacted the other side of the universe. this luks like a schit heap but is still worth 6 500 pounds sterling from the UK.. expensive. custom made exhaust by the bloke and race team that owns it...the carb is a 19mm thing that the only thing it can be described as, his class dusnt allow 21mm so this is a 19mm thing of a kart engine, he called it a simple diagfram and u have to inject fuel in it to start it, he called it a cold start, big suringe ful of AV-GAS fuk knows what that is. it runs on a mixture of this avgas shiit along with a friction eliminator liquid that costs $100 dollars a litre he buys it as 10th of a litre and mixes it with 2t oil and puts in with the avgas that is erm 10 times more flammable than petrol and when u set it alight it bubbles dusnt flame up oooo. he has 3 jerry cans full of the shiit in his shed along with his gsxr 1100 with a 20psi turbo and a nitrous kit that wheelies from 80mph to 160mph and he is part of the 200mph club has to prove it dus that in the speed trap with radar police gun. this bloke made me smile like an idiot if u have red this u may think u smell a bull excreting or u may think kewl i think in between but the little rs50 engine powered thing is very true i saw it with my own eyes and admired the mans knoleadge in two stroke tuning, for the people who now like micah u will know that this is true, he had really thick base gasket 7mm he said made from aluminum sheet he said he machined the same amount fron the top part of the cylinder also, has a close ration gearbox too and the gear oil is non0existant he puts in hydraulic fluid... the man was abosuletly briliant i wish i had a picture of him to show u lot, ill describe him, very rusty van long hair very scruffy likethe dude who rides a chopper bike but think not stocky, he has arthritis in his knees and hands from racing for so long and hes absolutely barmi.

04-23-2003, 04:01 PM
dont ask about the gearing but its quite rude the rear sprok is like off a 80cc dirt bike and the front one off a flipping polini minimoto, he made them himself. if u think the 114mph out of a fuking 50cc aint impressive then think about the 219.4mph the radar gun said that his nitrous gixer 1100 dus with more that 300bhp cant remember how much exactly. but this bloke needs to be put in a glass box and preserved in a museum, he is a lorry driver for a living and he can do burnouts on it says costs a fortune in tyres. he knew barry sheene worshipped him he also passed away not long ago he also and met "foggy" Carl Foggarty described him as a fuking twat, nasty insult here in enlgland!!the bloke is bonkers i want to write a book on him, what u peeps think haha :rollin: :lol:

I race for land speed records on the east coast and currently hold 3 records on my rs50. Even took the 125: 2 stroke records in the production class.
The top speed was 69.174 mph and that was bone stock. The speedo read 74. So it's 5 mph off.
