Bonamici Chain Adjuster Set for Aprilia RS 660, Black/Red

If your chain is tight it will be rough and cause excess wear on sprockets, bearings, and even the counter-shaft seal and it can also cause premature stretching and weakening of the chain. On the contrary, if your chain is loose it could hit the frame, cause a jerky throttle response, or worse even fall off!

• Made of T-6061 Aluminum Alloy
• Easy to install and adjust by turning the rotating knob and clicking into place,
• Quick and accurate adjustment of the rear wheel on both sides so you're chain is straight, rear wheel even, and at the proper tension.
• Sold in Sets (Left + Right).
