Servicing is dependent on many factors including the amount of riding, pace, and terrain/type of riding. MSC Moto recommends servicing steering dampers at the same time suspension is serviced, which is usually once a year. Steering dampers can certainly go much longer (5+ years) without servicing, however, it’s not ideal as the oil will degrade over time.
MSC dampers have a one-piece billet damping vane and output shaft, no rivets or sheer pins to come loose and induce slop or play in the damper.
MSC damper use quality o-rings and seals that don’t leak. After years of use when its time to service the damper, its straight forward. If you can service a front suspension, servicing an MSC steering damper is super easy.
Servicing the oil in and MSC damper is also very easy.
