DescriptionThe whole story▼
When riding position, grip security and structural integrity matter most, the Bonamici Racing SM55B clip-on handlebar for the BMW S1000RR K46 (2009-2018) sets the benchmark. CNC-machined from Ergal 70/75 aerospace-grade aluminium alloy and assembled entirely in Italy, this handlebar is engineered to meet the demands of track use while remaining a refined, street-legal upgrade for the S1000RR rider who refuses to compromise on safety or precision.
Key Features
- CNC-machined from Ergal 70/75 aluminium — one of the highest-strength aluminium alloys available, combining low weight with exceptional rigidity and fatigue resistance.
- Integrated anti-slip safety system locks the bar securely at your chosen position, preventing rotation under hard braking, cornering or high-speed vibration.
- Four-point mounting system — two fixing points at the handlebar clamp and two at the fork — delivers a rock-solid, play-free installation that does not shift under load.
- Complete set includes mounting discs and 250 mm handlebar tubes, making installation straightforward and removing the guesswork from fitment.
- Lighter than the OEM assembly without sacrificing structural durability or long-term fatigue strength.
- 100% Made in Italy — every component produced and quality-checked at Bonamici Racing's facility.
Construction and Safety
The SM55B is built around the principle that a handlebar is a primary safety component. Ergal 70/75 is the same aluminium alloy specification used in high-load aerospace and motorsport applications — it resists deformation under both sustained stress and impact loading. The anti-slip safety system is not merely a friction clamp; it is a dedicated security feature engineered to hold the bar's rotational position even when subjected to the chassis flex and vibration loads that a 200 hp superbike generates on track. The four mounting points spread clamping forces evenly across the fork leg, protecting the fork tube surface while eliminating the micro-movement that causes long-term fatigue in single-clamp designs.
Performance and Ergonomics
The 250 mm tube length and the SM55B's geometry are developed specifically around the S1000RR K46 chassis, providing a riding position that is committed and sport-focused without being unnecessarily aggressive for road use. The result is more direct steering feedback, improved body-weight distribution over the front axle, and a cleaner, uncluttered cockpit. Whether you are lapping a circuit or threading through fast mountain roads, the SM55B keeps you precisely located on the bike and in full command of the front end.
