Designed and made in Italy. Bitubo WMB series Nitrogen filled hydraulic shocks improve riding comfort and vehicle control. Most significant is that the damper units are fitted "upside down". These shocks feature adjustable spring preload and are available for most Harley models. Spring covers are available as an accessory. Your model motorcycle is given together with the stock shocks length. Feel free to take longer or shorter shocks from the same application group, but note that shorter than stock shocks lower the rear of the motorcycle. Fender to tire clearance should be checked after installation. Changing shock length will also change handling of your bike.
