lt 80 vs trx 90..

[SRH]

which is generally quicker?? we ride them as pit quads, me and my buddy have lt 80s...which we thought were quick...til my buddy got a old a trx 90 replica and dropped a 107 extreme pitbike motor in...my lt 80 with a dg pipe takes him til he hits 3rd..then its like im standing still

also how does the lt 80 compare to say the ltz 90...the new raptor 90 etc?

Your LT80 can be made to be as fast.
Seems 1/2 of the motors I do now is for adult pit bikes.

z90/raptor will never go as fast with todays aftremarket (or lack of) parts.
