I was wondering what is the best performing aftermarket piston which can still run on pump gas for a trx450r. Thanks for any and all answers!

Thanks alot! With the fast 500 kit you are still able to run on 93 octane?? Sorry for all the odd questions but I really want to get the right idea.

Yes 93 octane can be ran fine on 12:1 from all the so called experts I have spoken with :)

It depends on who you talk to. Laz at GTThunder said he would run race gas in the 450r if the compression was increased at all.
