On our 2006 Honda CRF450R Bike Build we’ll be installing Sunstar’s Works Z rear sprocket. Right now all I have to say is, this sprocket is like no other sprocket I’ve ever seen. I wanted to get some detailed pictures that really showed the craftsmanship that is being delivered by Sunstar sprockets. I’ll be sure to share more info on this sprocket when we install it on the dirt bike.
