Product Overview
Get a higher top end speed on your TT250 with our 45 tooth rear sprocket kit!
The stock 17 tooth front and 50 tooth rear is a great all around approach for off-road and surface street riding but this is a better option for riders who spend more time at higher speeds. This 45 tooth sprocket works with the stock chain so this is all you need to install it on your TT250.
Also offered in 49 tooth and 47 tooth variations.

15 front 50 rear. Too much screaming when just cruizing along. Now with a 45 rear it s ok. Don t need more speed, just a chill feeling.

4 50T > 45T Rear sprocket
Posted by Josh on Oct 12th 2022
Could only get 60mph ave. 75-67 downhill & 55mph uphill. Definitely worth the cost. Replaced it myself. 4 star because it should be on the bike from stock. Gained 10mph hwy spd and improved the acceleration in every gear. Dropping 5T does not lower your acceleration, it increases it. My '21 TT250 has a 17T front (stock). 17T F & 45T R or lower for higher spds. I get 67-72mph on flat surface, 65 uphill, 78 downhill. This gear ratio fixes most of the spd problems. Increasing HP is the only other option for more spd after this modification.
