Shock Absorber Type 641 Competition
The rebound damping in the fork is slightly overdamped in the standard version.
The rear shock absorber of the Triumph Tiger Sport 660 is fitted with a progressive spring as standard, but this has a dramatically poor block value, causing the rider to ride permanently in the second spring, which is clearly too hard. This makes the vehicle feel very uncomfortable and unstable. In combination with a linear spring with optimised rebound and compression damping, the Wilbers solution offers much better feedback from the road. This increases driving comfort and safety! To counteract the rear-heavy setting of the vehicle, we increase the negative spring travel accordingly.
With this shock absorber the compression tank is connected to the shocks´ body by a flexible steel hose. Therefore it is an ideal alternative for road motorcycles with limited space. The hose can be placed individually where there is enough space for example on the rear frame where air flow can provide additional cooling. The adjustment screws for high- and low-speed compression, each tunable in 22 clicks, can be easily reached from the outside. Rebound can be modified by an open bleed system in 22 clicks and the preload is continuously adjustable.

NOTE
Spring preload and rebound damping adjustable. Hydraulic preload adjuster recommended, since it's not adjustable withouh

Easy to order. Customer service responsive. Well packaged and quick to ship
The bikes handles better, I can now flatfoot with both legs down (I have a 30" inseam) and the lateral stand doesn't need to be shortened. Recommended modification!
Went to EPM with a major wobble and bouncing on my 2025Road Glide.
Mike installed new springs and heavier oil. Took an overnight trip to Maine the following. We road fast and hard. I have zero wobble and no bouncing since the install. If you have any suspension issues or questions, GO SEE THESE GUYS!!!! You will not bedisappointed.
Epm is a great company to work with a very knowledgeable and very friendly they answered all of my questions and completed the job in a timely fashion!
Epm crew is very knowledgeable, super friendly, and have a true passion for the sport! They are the only suspension company I’ll use
Thanks to Bryam for helping me figure out the right set of springs for my weight for the shock upgrade. Bought the YSS RG RG362 twin reservoir shocks and Fork Upgrade Kit for my 2018 Triumph Bonneville T100. Really transformed the ride! Great value for the money. EPM transaction was smooth for an international customer arriving on time. EPM gets suspension tuning!
Upgraded 2018 Bonneville T100 with this kit. Much stiffer and better damping than stock for sure. No front-end dive under braking and no pogo-sticking over road bumps. Excellent value for the money!
Fantastic! Really transforms my 2018 Bonneville T100. Bryan at EPM was able to spec the correct spring rate for my weight. No bottoming out! No more underdamped suspension! Excellent value for the money!
Product looks great. I have yet to install, but I can’t wait. I’m sure it’s gonna be wonderful.
Very helpful, Bryan in sales guided me to the exact product I needed for my bike.
I bought these for my 2017 GS Rallye and they totally transformed the bike! It now responds better in the front to sharp edged hits and in the Enduro Pro mode is very plush on the highway. The guys at EPM are very knowledgable and are riders themselves! I will be taking all my suspension work to them in the future. Give them a call you will be happy you did!

The fork springs were great. The springs sat higher then factory and alot less bottoming out now. Would highly recommend them to anyone.
