High-performance damper with dual springs. Main spring coil absorbs big hits and prevents bottoming while the secondary coil smooths out minor road imperfections. Provide a plush ride that’s not afraid to play rough. May require modification to exhaust brackets to open up clearance for belt. Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.
