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.

Fitment and Compatibility

The Bonamici Racing SM55B is designed and tested exclusively for the following model:

  • BMW S1000RR K46 — model years 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018
