FAQ

Does this fit the 2021 Yamaha MT-10?
Yes, the mount is compatible with MT-10 and MT-10 SP models, as well as most Triumph Street Triple RS models.

How is it installed?
The expanding rubber plug is cut to the appropriate length and pushed into the center hole. When the bolt is tightened, the plug expands against the tube walls creating an extremely secure attachment.

What if my bike has a threaded or closed hole?
If the hole is closed or the diameter is under 12 mm, we recommend considering the RAM-B-367U (bolt mount) or RAM-B-309-7U (handlebase mount) options.

Installation tip: If the mount feels loose in the tube, use some electrical tape to thicken the "stem" of the mount for a tighter fit. It needs to be snug in the tube to stay properly in place.
