mid race 70cc kits

[Grant]

im getting a aerox 50 and im going to tune it to be mid race and i was wondering what mid race 70 kit would perform the best but i also still want it to be reliable as i dont want to have to buy a new piston head and rings every 500 odd miles

500 miles is good for piston ring changes! The TP due+ is a nice cylinder to go for - cast iron and includes a single ring allowing less frictional properties. There are many good cylinders out there: Mhr rep, due+, sp2, s6r - It all depends on how you want the bike - Speed over reliability?

What other gear is going to be used, ie exhaust, carb, inlet, ign etc..

the motoforce is a great cylinder the porting is alot more aggresive than the mhr rep
its quality is very high
I am running one on my bike and have nothing bad to say about it

@butch
i was planning on deciding the cylinder i want then build the rest of the bike around that cylinder.
