Improved gear ration

I added five teeth (50) from OEM 45 on a Yamaha XT225. Top speed is of course reduced, but usable power from higher revs at top of gear is better. The "feel" in when to change gears seems right now. Gear ratio is closer together.

Good sprocket for the price.

This installed perfectly and seems like a nice sprocket. I have the same rear sprocket on another bike, putting some miles on it, and the sprocket's teeth show no sign of irregular wear. I would purchase again.
