Replacing the front caliper on my 2009 and one bolt broke. Someone (maybe me ) overtorqued the bolt. Local shop didn't have the OEM bolt in stock but had a bolt that fit.
The question - Is there a reason Mama Yama used a hollow bolt to mount the calipers?? Is there any problem using a solid bolt? Seems that would be stronger.

I've ordered the OEM bolt but am just curious.

Weighs less... Unsprung weight. Prob produce a death wobble at speeds over 19MPH. Same thing with putting more than 6lbs in the top box. DANGER WILL ROBINSON!

Thanks!
Wonder of they considered just using one caliper with one bolt. Much less weight.

Doesn't retain as much heat as a solid bolt as well as being lighter. You are living life on the edge by riding with a solid bolt.

Must be Friday!

Use either!! CAV is wrong, the death wobble doesn't start until 21 MPH and only if you have your hands off the bars.... the OEM bolt is likely an alloy or plated such that it resists corrosion better than off the shelf bolts. A drop of loctite and you can reduce the torque a tad.
If you need a spare front caliper....... PM me, I'm about to clear out some inventory......

I saw a guy on here once lose one of those bolts and replace it with a couple of zip ties.. Of course he was one of those corrupt individuals from Chicago.

Wasn't that an ABS malfunction?

Hollow bolt = easier to drill out & extract when some wrench jockey over-torques it...
