Failed Drive Shaft and Final Drive on my BMW R1200GS LC

My R1200GS left me stranded.

I was on my way to office on morning, merrily rolling along the usual morning traffic when I suddenly felt my rear wheel disengaged from the motor. Blipping the throttle only produced a cringe-worthy rattle with no power transfer to the wheel. And so I pulled to the side of the road and called BMW Assist.

I had to tow.

Grounded splines on the drive shaft mating surface.

Turns out that I’ve got the much dreaded drive shaft and final drive failure! The splines that mate the drive shaft to the final drive had somehow ground it way through and is no longer mating properly. At merely 70,000km and 5 years old, the un-abused shaft and final drive failure was disappointing! In fact, I just had my shaft serviced merely 6 months ago – completely removing it and greased up.

With gear 1 engaged and engine turned off, the drive shaft skips when the rear wheel is rotated.

Shit! Now, that’s gonna be an EXPENSIVE repair! My local dealer quoted me somewhere north of $5,000 for a new shaft and final drive. GULP! Now that’s some BMW TAX there!!

Not too apparent in this picture, but the splines were pretty worn.

Not willing to spend so much, I scouted around for some lightly-used parts. The internet is simply amazing! It quite literally connects the world together. Very quickly, I found a 2018 drive shaft that has seen some 1,200km only – shipped from Romania. I also found a 2015 final drive that has been used for approximately 20,000km – shipped from the UK for a great price. All-in at approximately a quarter of the dealer-quoted price!

So after spending less than a month waiting for parts and in the workshop for repairs, I’m finally re-united with my R1200GS LC. In the meantime, I’ve gotten a little bit more intimate with the G650GS Sertao – using it not only for my weekend off-road adventures, but also my daily runs to the office.

Hello baby! Good to see you again!
Re-united with my 1200GS!

Welcome home, my old friend!

  1. Were there signs prior to failure? I’m also worried with my 2012 Triumph Tiger XC when bike suddenly died while at gear 1 (about to move off from traffic light) but was able to start immediately.

  2. That’s scary and should not happen to a $50k-60k bike at 70,000km. Actually, I thought 70,000km should be almost nothing for an adventure bike of this caliber.

    1. When shit happens, it happens. Doesn’t matter how much the bike cost when new, doesn’t matter what brand or badge it wears. Just gotta deal with it and move on to enjoy riding it.

  3. I had the driveshaft disintegrate on my 2016 R1200GSA at 30,000 km. Fixed under warranty. The bill was close to $7,000 canadian dollars.
