Pin, One Armed Rear - BMW Single Sided (B2 Pin, '13-'24 see fitting notes)

Steel inner pin with aluminum outer sleeve for lighter weight on large diameter pin. This pin is slightly larger than the original B pin that was used on the earlier '05+ BMW's. This size hub was scaled in by BMW starting in 2013, but not all 13+ models will use it. Locking pin and washer included.  

Please see product fitting notes and/or our PDF fitting chart for more info. If you're not sure which hub you have, measure your hub with calipers and call us. We cannot provide dimensions on our products, but we can tell you which pin you'll need for your hub if you provide a measurement.

Some '25 models (R1300GS confirmed, R12S reported) use the "old" diameter hub which would make the F0099-007 appropriate for them.  The difference in diameter is less than 0.5mm so if you are not sure and are not able to measure your hub and call for verification of which pin you should use - just get the F0099-007.  It will work on the larger hubs that the B2 pin was designed for as well - with just a slightly looser fit.
