Ideal for those looking to maintain comfort and control over long distances without electronic complexity. Note: installation may require modifications on certain models (e.g. adjustment or spacing of the chain/belt guard on XL '86-'15). A shock absorber longer or shorter than the OEM may slightly alter the rake angle and steering responsiveness. Some references may be approved; check the certificate of conformity for road use and ensure sufficient clearance (swingarm, exhaust, chain/protection) before installation.
