I had surgery on my left thumb the end of May. My hand is 97% healed from the Surgery but is not as strong as it was before. I have ridden post surgery numerous times with the Stock cable clutch and adjustable KTM power parts adjustable folding lever.. my left hand was numb for over an hour after each time I rode..
The first Magura rc390 Clutch kit I purchased from Rottweiler was defective from the manufacturer,
A call to Magura and some trouble shooting resulted in Magura sending me a replacement kit. After installing the second Clutch Kit, I rode for close to two hours on the new clutch kit.... Mission accomplished my left hand was not numb after riding today.
A few observations after my test ride.. Beside a lighter clutch pull... shifting between gears both up and down is super smooth... I really was amazed how this Kit transformed the overall performance of my RC390.
I could not be happier with this upgrade. Rottweiler Performance shipped quickly, since I live In LA I had the Original Kit in 2 days.. Both Rottweiler and Magura are are 100% I would not hesitate to buy from either of these vendors.. one nitpick the lever on the HC1 master cylinder in the kit I purchased has a long lever.. this is not my issue. I would have preferred to have a folding lever....HC3 master cylinder comes with folding lever but the master cylinder is almost twice the price of the HC1 and the entire clutch kit.. Overall this is a great upgrade if you want a hydraulic clutch on your RC390
