A buddy of mine from work rides an '08 Crossbones. The other day he mentioned that while enroute to bike week his bike broke down and had snapped all five of the bolts holding on the rear wheel drive sprocket. Fortunately, the mechanic was able to get the other half of the bolts out of the wheel so he didn't have to replace the whole wheel. Has anybody ever heard of a problem like this? I was just wondering if this is an issolated freak incident or something to be concerned about. Is it recommended to replace those bolts every few years as a safety precaution? The only thing I can think of that might have caused this is if the bolts weren't torqued down properly or the wrong loc-tite was used. Any thoughts?
