Penske 8981 Shock Installation

The CBR600RR's Unit Pro Link suspension represents a departure from previous conventional designs in that the top mount of the shock is bolted to the swingarm itself, rather than the frame.

For many riders, the stock shock unit may be underspring for their weight. Furthermore, it offers no means of adjusting ride height. On a bike that is arguably less flickable than some of its competition, the ability to raise the rear end can yield substantial handling improvements.
