Rizoma Clutch Lever. Thorough research has proven that at high speed the air pressure force on the clutch lever puts the circuit under pressure rendering it inactive. Having been subject to long-terms studies in a wind tunnel, the lever has been modified several times in order to make it less sensitive to air pressure action, even at a very high speed. This important achievement led the company to patent the original design. The precise ultrathin front lines, as well as the shape, assure a better grip. The levers are created in line with the latest technology: a broad range of adjustments, including movement on the bearings with return springs, make it possible to improve their functionality, reliability and durability. The articulated joint allows the lever to fold in case of fall and thus avoid breakage.
