The stock KLR 650 subframe bolts are known to break, which can leave you stranded. The Eagle Mfg. Drill Through Subframe bolt upgrade kit solves the problem. The kit replaces both stock upper 8mm subframe bolts with one strong 10mm bolt that runs through both sides of the subframe. It also comes with stronger lower mount bolts that replace the stock as well. This is the ultimate kit for strength � necessary when running a lot of cargo weight. Drilling required � Drill bits included.
