Some practical points for installation: on certain XL models ('86–'15), it may be necessary to space or modify the chain/belt guard to ensure clearance. A shock absorber longer or shorter than the original may slightly alter the rake angle and thus the steering responsiveness. Check the travel and clearances (swingarm, exhaust, belt/chain guard, tyre) before installation.

Some units are road-legal; consult the manufacturer's certificate for the up-to-date list. Recommended: Heavy Duty versions for motorcycles frequently carrying loads close to the manufacturer's maximum.
