The Ohlins YA588 STX 46 Blackline rear shock is built for riders chasing a more controlled, composed feel from the rear of their Yamaha MT-09 (FZ-09), Tracer 900/Tracer 9 (FJ-09), or XSR 900. It combines modern damping behaviour with the understated Blackline finish to suit bikes where appearance matters as much as function. Adjustment range is provided so you can tailor ride comfort, stability and response to your load and road conditions.
