Renthal® 1-1/8” (28.6mm) street handlebar clamps are designed to allow the mounting of oversized 1-1/8” handlebars, such as the Twinwall® and Fatbar® to motorcycles which are equipped with 7/8” handlebars as standard.
Designed to use the OEM rubber cones.
CLAMPS
The handlebar clamping surfaces are accurately machined. This ensures a perfect fit between the handlebar and clamp which reduces possible movement. Available in different offsets and anodised to prevent corrosion.
CNC-MACHINED
Both the clamps and the bolts are carefully CNC machined at the Renthal Factory.
Taking a billet of material our CNC machines use various tools to machine away material, leaving the final product ready for finishing.
BOLTS
To minimise the chance of bolt failure, special attention has been paid to the design. The unique bolt head is designed with a part hemispherical seating blended into the shank. The bolt is plated and de-embrittled to resist corrosion. A stainless steel spring dowel pin prevents rotation when tightening.
MATERIAL
The clamps are CNC machined using a high-strength 6082 T6 Aluminium alloy. The bolts are CNC machined from nickel chromium molybdenum 817M40 steel that is both hardened and tempered to grade 'W'. Corresponding to an ultimate tensile strength of 1075-1225 N/mm or 70-80 Ton/in.
