Is there such thing as a enduro high compression piston ,or can anyone recom mend the most reliable high compression for the 04 trx 450r?

JE 12:1 or CP 12:1

3 ring for more longevity.

sounds good
but what year quad do you have? Neither of these will help if you have an 06+

Thanks BATCH450r , I didnt realize i put this ? in the raffle section. What do you know venom 12:25 does he have reliable three ring hith comp piston?

the 3-ring for longevity is utterly incorrect.....

if the rings are seeing the same amount of travel (and they are), i don't see what "reasoning" people are using to promote the longevity theory..... if anything, the 2nd compression ring of a 3-ring setp scrapes away even more lube from ever reaching the ring that sees the most heat\ pressure.....the top ring

what 3-ring setups have is better oil control...

now...longevity IS a function of ring drag & ring material\facing.....

and low tesion + nitirded rings are what you want for the longest possible life....but when they are low tension, they also benefit from the increased sealing pressure during combustion from lateral gas porting....


so, if you want a 12.25:1 3-ring, low tension, nitrided, gas port assisted piston..... you only have one choice.... and that's Venom's premium endurance racing piston...

personally i think it's cool to actually have technical facts in the answer to a technical question....but that obviously isn't the way everybody rolls.....lol.....

Thanks Mixxer i ordered my piston !!!!!!!!!!!!
