BC305-(014/016/017) | Installation Instructions for Triumph Street Twin Four Bolt Risers

posted this on Jul 1, 2016

Upgrading your stock handlebar clamps to BC's Four Bolt Risers not only makes your bike look cleaner, but it also makes your riding position significantly more comfortable. The Four Bolt Risers can be installed with a BC Spacer to give them even more of a lift if you're a bit taller than average. Putting the Four Bolt Risers on can be done with the triple clamp still on the forks, but for the easiest installation experience, we recommend taking off the triple clamp and going from there. If you have any questions about how to get to that point, don't hesitate to check out the guide on our Resource Center covering how to remove the triple clamp from a Triumph Street Twin.
