I have a 1985 TRX 125. Ive been riding for a while and just wanted it to have a little extra kick. Do any of you out there know of any mods that could be put on for this year. Thanks.

I had one for a year, it shifted so bad i sold it.. there are no performance parts that i know of becaue that engine is just a bored and stroked ATC 110, so it is at its limit in stock form (but still will last forever)

DG makes a header for it about
$80.00. a k&N filtr helps to.Dennis
kirk use to sell a cam by big AL's
about $25.00. Check your valves set
the intake at .004 instead of .002
this will help some too.

Looks like your browser stuck:) I totally frogot about the cam, its been a while. Hope they still make it.

dg makes a pipe for the trx125 and it would probley give you more power the pipe is in the 1999 dennis kirk mag, i have 2 trx's and they are a good machine do you know the top speed for the 125 any way one of mine is stock and one has been bored out.

there is a huge difference between the 86 and the 87 125 as the 87 uses nothing in common with the older ones..my old 85' would top out in the low 40's

The difference between the 86 and the 87 is the 85,86 mod had a cylinder that stuck out towords and front tires and the 87 and up had a cylinder that stuck strait up in the air towards the gas tank.:}
