• Material: steel – black finish (without covers).

Before installation: check the homologation applicable to your model and consult the most recent certificate. On certain models (notably the XL '86–'15), spacing or modification of the chain/belt guard may be necessary to ensure sufficient clearance. A shock absorber longer or shorter than the original may slightly alter the rake angle and handling; also check the wheel/swingarm travel to avoid any contact between exhaust/axle or chain/protection.
