I bought this to be used in my 1198 WSBK build but I have since found the specific damper (SD3120) used by the bike and no longer need this. This damper was used by bikes in WSBK as well as MotoGP, however, the GP ones used magnesium body's. It has the additional valve on the opposite side of the adjuster screw that the road dampers don't have. I contacted an Ohlins centre who confirmed it is not bike specific so can be used on any platform and has stroke 68mm. It has some light damage from it's previous life but is still in good overall condition. This style of damper was used by the 999, 1198 and 1199 world Superbikes. If you have any questions shoot me a message. Looking for £500 including postage.
