Worked great on Coleman AT125UT 4 wheeler
I put this on my grandson’s Coleman 4 wheel to add a little low end power. It has one tooth less than original. Of course the chain had to be shortened but I was replacing the chain anyway.

Fits TRX90
Definitely fits and works for a Honda TRX90. Stock sprocket is 13 tooth I went up to 15 tooth, cut the pink wire re-jet the carb and gained 7mph GPS verified. That's a whopping 31% higher top speed! The low end is still fine in 1st and 2nd gear. 3rd and 4th can now wind out A LOT further. I am 6'2 235lbs and it does not lag because I went up 2 teeth. No need to change the chain length. Just move the axle up a bit. There are 4 17mm (if I remember correctly) bolts and 1 12mm adjuster bolt that get loosened and it'll make space for the new bigger sprocket. Best $8 I've spent on this little bike. Get it if you want a higher top speed!

Installed on Vader 125
I took out the stock 14t and put the 15t in my Vader 125. Wasn't a crazy change like the 16t or 17t upgrades cause because I still wanted to retain some low end torque for stunts. All in all extremely pleased w/ the way this sprocket performs.
