Shock Absorber Type 644 WESA Dynamic Front
WESA Dynamic suspension for the BMW R 1300 GS - more comfort, more control, more safety BMW has set new standards with the market launch of the BMW R 1300 GS: The standard, semi-active suspension automatically adapts to road conditions and load. As an option, BMW even offers adaptive height control, which lowers the motorcycle by 30 mm when riding slowly - a real highlight in terms of riding comfort and safety. But we go one step further. With our WESA Dynamic solution , we get the maximum out of the suspension of the R 1300 GS: Noticeably more comfort compared to the standard suspension Typical GS ride comfort - the way you know and love it Optionally available: lowering of 30 mm - perfect for smaller riders This makes the BMW R 1300 GS even more versatile, comfortable and accessible. What needs to be considered? For the modification, the original standard suspension must be sent in for coupling . The cost for this is € 149 . Alternatively, you can make an appointment with one of our trained WESA partners or directly at our factory in Nordhorn. Our quality promise: 5-year warranty on the WESA suspension Including ABE (general operating license) Experience your motorcycle in a new way - with WESA Dynamic Note: For the coupling with the WESA system, it is necessary to send in your original DSA shock absorber. The coupling costs are 149,- EUR per shock absorber.

5 star
Everything I wanted and never knew I needed. Spec’d perfect. Didn’t even have to adjust sag.
100 times better than stock, wife on back says nothing compared to ouch or ugh when we hit a bump
I have spinal stenosis, this was exactly what I was looking for.
huge improvement !
replaced the ktm garbage, which had completely failed and was bouncing and bouncing and bouncing
Excellent service throughout. Thank you!
Fits perfectly
Very high quality
If you have a 40–50 lb rider on a Husqvarna EE 5 (or KTM SX-E 5 / TC 50), swapping out the factory shock spring for this 25 N/mm spring is hands-down the single best suspension upgrade you can make.
The stock rear spring is notoriously oversprung for young kids. Before installing this, our rider was getting bucked over braking bumps, the rear end skittered out in flat turns, and it was physically impossible to dial in correct rider sag—even backed all the way out on the preload collar.
Swapping to the 25 N spring completely transformed the bike's balance:
True Sag Numbers: Finally allowed us to set proper race sag (targeting ~60–65 mm) while still maintaining healthy static free sag.
Chassis Balance: Balances out the front WP air fork so the bike stays level and planted instead of riding stinkbug into turns.
Instant Confidence: The rear wheel actually tracks through acceleration chop and ruts now rather than deflecting. Our rider felt the difference on lap one—much less fatigue and far more control over rough, choppy sections.
Fit and finish (47x130) are spot-on, drop-in replacement with the stock WP shock collars, and the coating holds up to roost and power washing. Don’t waste time fighting the stock spring if your kid is under 55 lbs—this 25 N spring fixes the rear end completely. Highly recommend!
Awesome addition to the 390. The spring had made 2 up riding much more comfortable.
Sterrring damper is amazing! Got rid of all the head shake at high speeds. I only have it 5 clicks in and it's working as it should. The guys at EPM are great. Thanks!
