Lightened Flywheel Service
Send your flywheel to us for lightening.
The stock TTR125 flywheel is extremely heavy and was designed to make the TTR easy to ride for beginners. If you're looking for better overall responsiveness this is your best "bang for your buck" performance improvement for the TTR!
For only $55 we will lighten your flywheel and send it back to you.
A lightened flywheel greatly increases bottom-end acceleration, and improves throttle response. Allows you to flip the front end up easily in 1st, 2nd, or 3rd gear to hop over logs and obstacles while trail riding without having to gas the throttle and pull up on the handlebars!.
