Help - Top Clamps
HDB Modular Top Clamps.
With the HDB handguard system we begin by replacing your stock handlebar top clamps with a one piece HDB Modular Top Clamp.
There are 5 sizes to choose from, 90, 96, 98, 100 and 106mm.
Carefully measure your handlebar top clamp bolt pattern, and then choose a top clamp from the list.
Our top clamps only support 1 1/8" bars, that is the diameter at the clamping surfaces where the top clamp mounts, not to be confused with the grips and control clamping diameter, that will be 7/8".
