We just took delivery of this combo and wanted to show off the new bling on our 2013 Yamaha YZ250F. It has not been on the bike long enough to do any real evaluation, but there is nothing like the look, sound, and feel of a new chain and sprocket on your ride.

Sunstar has been in the game for a very long time and the machined aluminum Works Triplestar rear sprocket and 520 MXR1 Motocross Racing Chain are the latest addition to their line.

We went up two teeth from stock (from 50 to 52) to help get a little bit more low end bite out of the 2013 YZ250F.

Our combo includes the Works Triplestar Rear Sprocket (anodized black), 520 MXR1 Motocross Racing Chain, and Steel Countershaft Sprocket.
