From what I've seen on CL, my budget is more likely to favor an older (2004 or older) R1150R or even R1100R vs. an R1200R anyway. Trying to stay under $5k. I've seen 1100's for as low as $3,000 in recent months.

MCN did an article on the BMW Final Drive Failures some time back, but you can't get to the entire article without being a subscriber. It seems that the majority of problems came with the EVO paralevel drives on the 2004 and later models, with the hollow rear axle and 50 mm hole.
This snippet is from the MCN article
As to the number of occurances of this failure, statistics are difficult to gather as BMW will not talk about it on or off the record. These failures were insignificant prior to model year 2001. Fact: of 38 Palever BMWs that entered the 2007 Iron Butt Rally 14 were R1200 models, that is EVO Paralever bikes; four did not finish due to final drive failures, a 29% failure rate. EVO paralevers are 2004 and later models with the hollow rear axle and 50 mm hole.
A symptom cited in the article was oil leakage around the final drive seals eventually spreading to the rear wheel; others include metal particles on the magnetic drain plug (it was suggested one be fitted if not present).
There is an extensive technical discussion of failure modes, preload pressures, pinion gear's needle bearing, final drive lubricant change frequency, viscosity of the fluid. The article notes these are only theories as the BMW technicians who have examined cases of this occurance are silent.

What wasn't discusses in the MCN article, is the FD spline failures, and that was the issue with our RMMRC club member who switched to the Explorer. That was the issue of two failures with his BMW.
I have no idea what current statistics are for models beyond 2007, but there does appear to still be a lot of forum posts and issues reported.

You're probably right Curtis, I do tend to let them sit around too long. Not enough time to ride more than 6-8k per bike and keep my day job. Either less bikes or more time off. Tough decision...The FD failures have happened across all variants of the line, not just GS bikes. I believe that it is a problem with the 1150s too, but not sure which FDs were more prone to have trouble.SteveOn Nov 22, 2013 7:27 AM, <emrat@googlegroups.com> wrote:
