This product was developed for our RD350 engined Yamaha TZR-250 which has a single sided swinging arm from a Honda VFR/RVF-400. The rear wheel hubs on these swinging arms do not have a cush drive. Hence, we designed and built a conversion that incorporates a cush drive into the sprocket carrier.
This is yet another product that came out of our RD350 engined Yamaha TZR-250 project. We wanted to fit a smaller, lighter rear brake caliper. After some consideration, we decided to use the extremely lightweight rear caliper by ISR of Sweden. While this shaves a considerable amount unsprung weight, it really only works on a small, lightweight 2-stroke bike. Maybe it should be considered a "hill holding" brake rather than one to use to bring the bike to a stop. Still, we like the look of it!
You will find additional picture of this conversion in the TZR-250 Hybrid gallery.
