I haven't been around here much in the last year or so, because I bought a 2023 BMWR1250gsa last April. I still have my Super Tenere though. Dealer wouldn't give me much for it on trade, so I just kept it. Here's what my dealer told me about the driveshaft issues last spring: After lots of testing BMW traced the failures to sudden changes in rear wheel speed when getting the bike airborne and landing hard. This confused the bikes dynamic traction control. BMW then came out with an updated download for the computer. There was also a corrosion problem and a little drain thing was added to the driveshaft housing. Dealer did both of these changes to my bike before I picked it up. This may explain the issues on GSs and GSAs, but who gets an RT airborne? This dealer also mentioned that they have not seen any driveshaft failures. If BMW wants to put a new driveshaft in it on their dollar, so be it.
I have almost 18,000 miles on mine with zero issues. The bike has been great and my dealer has been great. I knew going in that this would be an expensive endeavor. I take it in for everything, oil changes, tires, inspections etc... I'm tired of working on everything. Most of the time I make an appointment and they service the bike while I wait. To me it's all worth it because the bike is such a joy to ride. I have 2 more years and 18,000 more miles of warranty left. It's been a long time since I put that many miles on a bike in a year. Last season I put 17,500 on the BMW, 2,500 on my HD, 2,000 on my DR650, 1,000 on my S10 and a few hundred on my old Triumphs and Norton.
Next time I go to my dealer, I will get the latest info the driveshaft thing. Just thought I would share the info I have so far, don't want to start another BMW pissing contest!
