We've increased the thickness of the aluminum side plates and given it a modern look with see through cutouts. That allows for quick clean out of crud - plus it looks like a modern big-bike style chainguide. The side plates are anodized in black with a silver chamfer and the "BBR" logo is laser etched. Modern, dished flange-head bolts replace the button head allen bolts of the old design. HDPE plastic feeds the chain onto the rear sprocket to prevent tossing the chain. Tossed chains often result in broken engine cases - not to mention lost races.
NOTE: This now includes hardware for both the stock and BBR swingarms. (10/01/21)
