Brake perch clamp bolt AWOL

[markjenn]

Just a quick note that you might want to loctite and/or monitor the tightness of the pinch bolts for the brake and clutch perches. I was washing my bike after a 800-mile, three-day tour and noticed the lower clamp bolt on the brake perch (right side) that clamps the brake perch to the handlebar had vibrated out and was missing. It's a 6x22 mm fillister head bolt with a T-30 torx head.

Strangely, the BMW fiche for the S1000RR shows this bolt "NA". I substituted another 6mm bolt I had lying around and will take the other in to the BMW dealer next time I'm there to get it matched up.

Also note that these bolts have a specific tightening sequence. You tighten the top one fully before tightening the bottom one. The clamp is asymmetric and you want the top of the clamp to be fully seated against the perch before you tighten the bottom which handles all the pinching load.
