    Question 88 125 motor?

    I have a perfect running 1988 trx 125 motor and was wondering what it might fit into as far as 3 wheeler frames are concerned. I know it will fit the 86-87 atc 125 frames, but what about any other, more common ones? Thanks

    WRONG!! The 87-88 TRX and 86-87 ATC125m motors are completely different than the 110 motors. The 110 motors are a lay down style, while the 125cc's I listed above are a upright style.

    You might be able to fit the motor into a 185-200cc chassis, but you wuld need to modify things a little. The 125 uses a 420 chain and the bigger machines use a 520 chain. The electronics are a lot different, and more.
