Was trying to decide wich one to buy and wanted your opinions!! To see mmore about either of these kits go here: Aprilia RS50 Engine Performance Parts (http://www.af1racing.com/store/Scripts/prodList.asp?idCategory=65)

the malossi is double ring'd so it will last much longer without a rebuild, better for street driving. The top performance probably puts out a little more power but you'll have to do a piston/ring rebuilt far more often. plus the malossi is aluminum

How much more power? And how often would I need to do a rebuild on the 75cc?

P.S. RSR what the hell is that a picture of?

i dont know how much more power, but i hear the tp75 is strong with the jolly moto exhaust. I'm happy with my malossi and jolly combo. I'd say you'd need new rings every 1500 miles and a new piston and rings every 3000

Thats pritty often...I'm realy gonna have to think hard about this one for a while...everyone elses opinion would be appreciated..........RSR WHAT THE HELL IS YOUR PICTURE OF?

Why is it between the 68/75 and not the 68/72? Thee 68 is a street kit, as is the 72.

Because the 68 is aluminum and the 72 is near the same as the 75 except with double rings and if it were between those two I would go for the 75....What I have to way out is if the added performance of the 75 is enough to compensate for the added maitnence.

I was curious to every one's reasoning behind choosing the 68cc and not the 75cc

1: aluminum
2: double rings

those were my reasons. the power difference is going ot be small

Well it sounds like i'mn going with the malossi

As I've already said, you're comparing apples with oranges.

The tp 75 kit is made for pure power with a lot of topend, the 68 and 72cc kits are double ringed street kits with good lower torque.

If you decided to pick the 75 over the 72 merely because it's a bigger number, then you're making an ignorant decision and losing valuable information by shrugging off the reasons as to why one would get a street kit.

Oh...I didn't know that....I assumed the 72 and 75 were the same kit except one had slightly lower performance....But I still think I'm going to go for the malossi....It seems everyone I've talked to thinks it's best...But thanx for clearing that up!

how hard did you find it to drop the forks in the triples?

agreed.
besides, the malossi tends to get (2) hot quick.
i'd go for the race TP, the malossi aint that powerfull, its comparable to a gilardoni.

Well I guess I'm going to have to do a little more thinking.....Droping the forks in the triple clamps was very easy. But make sure you have an extra person their to hold the bike so when you loosen it up it doesn't drop too far on you. Also don't lower them too much or your fork will bottom out if you hit the front brakes.

i got the tp 72cc and i have been raggin that thing for time on the strret not a problem alot more power, ignore the 75 that is the race 1 unless u just wanna race.

how is the low end torque with that kit?

With the stock pipe I can get plenty of power starting from 6k, and there is a HUGE improvement over the stock 50cc at any lower-rpm (as well as high, obviously).

I love the TP72 kit, but alas I haven't used the malossi personally, so I can't give you a direct comparison.

The malossi kit has been much more openly available via AF1 than the 72cc kit, which has only been available for 3 months or so.

Micah says the 72 has the best low-end torque, but after reading these boards for a few months, I can safely say you really can't go wrong with either one (seeing as they're both highly regarded double ringed street kits).

Good luck with either decision you make, and enjoy.

Straight out of the box with no porting, no setting the squish, no timing advance/retard, etc if you compared the Malossi 68, tp72, and tp75(all using same carb/pipe)... the TP75 peaks about .5-1 hp higher than the Malossi but the 75 will have a little more torque. Running the Malossi with 1 ring (top only) would make them about equal if you don't mind rebuilding more often. The TP72 isn't a bad kit, but the other 2 make more power.

We race with a Malossi 68 kit, and personally I think they're the best all around kit (cheap,great performance,reliable). The TP75 performs great, but I've seen one that was cracked from a failure. Any failure could potentially ruin a cylinder, so you couldn't go wrong with either kit... just don't seizure it and you have nothing to worry about :D :D :D

You guys aren't making this easy for me lol....Great info but now I'm realy stuck....All 3 sound great and have their separate advantages...But if I'm looking for 1st most better acceleration and torque what kit should I go for? I would love better to end as well but the acceleration is most important to me.

AF1 said that the tp 72 has the most torque pulling around 5k rpm.

I got to go against the grain here. MY out of the box Malossi 68 seemed to be noticably faster (no dyno done) than the TP 75 that I bought the bike with. It had a harder hit at the power band and more overrev. Doesn't seem to be what other people are saying though. I have been racing the same top end for 2+ years with no probs. New rings and hone at the end of the season are the only maintenence.

Alex52686

So if I'm looking for acceleration and reliability go for the tp72, if i want a mix of top end and reliability go for the malossi 68, and if I want straight up speed go for the tp75.

Is that a fare assesment????
