DescriptionThe whole story

Engineered for riders who demand trackday precision without compromising on safety, the Bonamici Racing SM55 handlebar is a direct-fit upgrade for the BMW S1000RR K46 (2009-2018). CNC-machined in Italy from aerospace-grade Ergal 70/75 aluminium alloy, it raises the bar by 15 mm and angles it 6.5° downward to put you in an aggressive, controlled riding position the moment you leave the pit lane.

Key Features

  • Integrated anti-slip safety system locks grip position under hard braking and high-load cornering, reducing the risk of handlebar rotation in critical moments.
  • CNC-machined from Ergal 70/75 high-strength aluminium alloy for exceptional rigidity and long service life under race conditions.
  • 15 mm rise combined with a 6.5° downward sweep optimises ergonomics and sharpens steering input on the S1000RR's geometry.
  • Four-point mounting system — two clamp points on the handlebar and two at the fork — delivers a rock-solid, rattle-free installation.
  • Precision-engineered fitment specific to the BMW S1000RR K46 (2009-2018); no modification or adapting required.
  • 100% Made in Italy, manufactured to Bonamici Racing's exacting quality and safety standards.

Safety First: Why the SM55 Stands Apart

Unlike generic clip-on upgrades, the SM55 is built around a dedicated anti-slip safety system that prevents rotational movement of the bar under extreme loads. Combined with a four-point mounting interface shared between the handlebar clamps and fork mounts, this ensures the assembly remains geometrically stable whether you are trail-braking into a chicane at the circuit or hustling through a mountain pass. The Ergal 70/75 alloy used throughout offers a superior strength-to-weight ratio compared with conventional 6061 aluminium, resisting deformation even after sustained high-stress use.

Ergonomics and Riding Position

The SM55's 15 mm rise positions the hands slightly higher than stock clip-ons, alleviating wrist fatigue over long stints while keeping the body weight loaded over the front wheel for confident corner entry. The 6.5° downward sweep maintains a sport-forward lean angle that suits both sprint track sessions and spirited road riding, making this one of the more versatile handlebar geometries in the Bonamici catalogue. The result is a steering feel that is more direct and communicative, with improved force transfer from hands through to the front axle.

Fitment and Compatibility

The Bonamici Racing SM55 handlebar is designed exclusively for the following motorcycle:

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

Always verify your frame code and model year before ordering. The part number SM55 is specific to the K46 generation; it is not compatible with the K67 (2019-on) S1000RR without modification.
