          Sunstar 520 Steel Rear Sprocket

          Sunstar is the largest OEM supplier of sprockets and brake rotors in the world. In fact, your motorcycle probably came from the factory with a Sunstar sprocket.


          • Constructed of the highest-quality 1045 high-carbon steel
          • Exclusive heat treatment for added strength and wear resistance.
          • Most are zinc plated and have a baked on durable paint process for corrosion resistance.
          • The strongest, longest lasting steel replacement sprocket available.
          • Nearly all motorcycles come equipped from the factory with this sprocket.
          • *Note: Part is bike specific, may vary from image.



          Rated 5 out of 5 by from Durable, good value I use Sunstar steel rear sprockets on both my bikes. Very durable when combined with a quality chain (ideally a DID VT2 sealed chain). IMO these steel sprockets are a much better value for the average recreational rider than aluminium ones. Website image is not always accurate, the sprocket isn't full but has lightening cutouts/holes just like most others, overall not much heavier than aluminium,.

          Rated 4 out of 5 by from Does not include countersunk bolts Ordered the Sunstar 48T rear sprocket for my WR250R. Cannot use the original bolts as they are not countersunk. Needed to purchase a Mooseracing sprocket lock bolt kit to complete installation. Save yourself additional shipping expenses and order the bolt kit at same time as the sprocket. Sprocket fit perfectly with the countersunk bolts.

          Rated 4 out of 5 by from Steel rear sprocket I purchased this for my Husqvarna 510 motocross bike. It will eat an aluminum sprocket in just a few rides. This steel sprocket will last all season no problem.
