2021 R1250RS Handlebar Conversion
As mentioned in other reviews of this superb Wunderlich product, the much more relaxed yet confidence-inspiring riding position transforms an already incredible bike into one that has the advantage of both the OEM windscreen/fairing and more upright, wider bars. I also agree that handling at slower speeds is not just mildly better, but much, much better. I was not so opposed to the original sportier riding position, because it reduced vertical stress on my lower back after numerous surgeries. However, I found I was just not enjoying my ride as much -- aching neck and back muscles; wrist pain; and so on. I did a 200 mile ride with the new bars yesterday, and had an absolute blast! Totally enjoyable ride in some gorgeous central Arizona topography. I am so much happier with this new RS; and, in my view, the handlebar conversion is as awesome to-the-eye as it is to the overall handling of the bike. It looks absolutely perfect.
A few notes on the install:
I would like to see the necessary hydraulic clutch fluid bleed mentioned in the instructions on the website (although perhaps I missed it? If that is the case, I respectfully stand corrected) The clutch line needs to be re-routed, and thus must be disconnected at the clutch fluid reservoir. Despite this, I was not comfortable with the new position of the line (which is necessary to prevent binding caused by the taller, wider bars). Maybe I just did it wrong! In any event, I chose to order a clutch hose extension adapter designed specifically for Bimmers from Voit MT in Germany, and I feel much better with this approach (which does not require rerouting of the clutch line). It's also very, very easy to install, as is bleeding excess air from the line. DO NOT be intimidated by this step. Take your time; it is not at all difficult.
I think it a good, precautionary step to cover all nearby fuel tank and fairing parts with a soft towel before disconnecting the clutch line and removing clutch fluid reservoir cap. Despite my best efforts, it was hard to not have at least some minor spillage of the blue hydraulic fluid. Also: I think it a good idea to have on hand an extra small bottle or two of the correct mineral oil -- which is fresh and new, had not been exposed to air, etc. And do not overfill the reservoir. After carefully cleaning and replacing the filler cap, tighten the TORX screws LIGHTLY -- do not over-tighten. I'm thinking not much more than about 2 Nm (that is NOT a BMW torque spec. It's what I came up with after a bit of experimenting)
Take your time and enjoy working on your bike! This handlebar conversion will reward you for doing a quality job and not rushing to get it done. SUPER HIGHLY RECOMMENDED!!!! Safe Riding!! :)
