Shock Absorber Type 641 Competition
Originally, the fork was fitted with linear springs. These have been replaced by progressive fork springs, which offer a much better initial response and provide more reserve in the second spring rate compared to the stock setup. The rear shock features a slightly stiffer spring combined with optimized rebound and compression damping for improved control.
The suspension geometry on both the front and rear axles has been sensibly refined by adjusting the negative spring travel. The stock setup had slightly excessive negative travel, which has been corrected using a minimally shorter suspension strut while maintaining the original seat height. The result is more precise handling, greater comfort, and improved safety.
This shock absorber connects its compression tank to the main body using a flexible steel hose, making it an ideal choice for motorcycles with limited installation space. The hose can be routed where there is sufficient room — for example, along the rear frame — where airflow also aids in cooling. The external adjustment screws for high- and low-speed compression, each with 22 clicks, are easily accessible. Rebound damping can be adjusted via an open-bleed system with 22 clicks, and the spring preload is continuously adjustable.

Perfect fit, perfect replacement for the factory Showa. 1993 BMW R100R rides like new again!
Very high-quality shocks. Pricing is reasonable for what you get. Super easy install. Highly recommend.
I tried two after market rear shocks on my‘23 Road Glide and wasn’t pleased at all with either set. My wife gave me an evil eye when I-told her I had ordered another set (3rd set) of shocks. About an hour into our first ride on the Wilbers she acknowledged the Wilbers were a huge improvement.
The shocks are very easy to install and make the ride as smooth as can be.
Fantastic upgrade that really improves the ride.
Can’t rave enough about the set-up! Two weeks after installation, I went on a 9 day ride from Staten Island NY to Key West FL and back, with various stops in between. The bike handled so smoothly, it was the best long ride i ever had. Never bottomed out either! I’ve been recommending the Wilber’s Nivomat suspension & EPM Performance to everyone I meet. Thank you.
What a great product. So much better than stock. Easy set up and go. No more 3 different adjustments.
