DescriptionThe whole story▼

Purpose-engineered for track use and built to the exacting standards that Bonamici Racing is known for on the World Superbike grid, the B001/B001R rearset system transforms the riding position of the BMW S1000RR and HP4 K46 (2009-2014). CNC-machined from aircraft-grade aluminium and finished in a hard black anodised coating, these rearsets deliver millimetre-accurate adjustability so every lap can be set up with precision.

Key Features

  • Available in standard shift (B001) and reverse shift (B001R) configurations — ideal for both road and race use with quick-shifter compatibility in mind.
  • Millimetre-precise positioning of the rear brake lever and gear shift pedal lets you dial in the exact ergonomic setup for your riding style.
  • Integrated return spring in the rear brake lever ensures consistent, predictable brake feel and smooth lever return under hard braking.
  • Anti-slip footpeg platforms provide confident grip even in wet or aggressive cornering conditions.
  • Rubber-tipped gear shift pedal tip improves tactile feedback and comfort during repeated shifts on track.
  • Full CNC-machined aluminium construction guarantees tight tolerances, long service life and minimal flex under load.
  • Hard black anodised finish resists abrasion, corrosion and track-day wear without adding unnecessary weight.

Track Performance and Build Quality

Bonamici Racing develops its rearset systems directly from motorsport applications, and the B001/B001R carries that heritage onto your S1000RR or HP4. The CNC-machined aluminium body eliminates the flex and imprecision associated with cast or pressed components, giving a direct connection between rider input and machine response. The millimetre-increment adjustment range on both the brake lever and shift pedal means you can replicate your preferred position after every service or setting change — essential when consistency matters on a timed lap.

The integrated return spring in the brake lever is a detail that separates a race-grade rearset from a cosmetic upgrade. It maintains constant tension on the lever, removes any dead travel and keeps brake modulation predictable from the first corner to the last. Combined with the anti-slip footpeg surface, the system keeps the rider planted and in control under maximum deceleration.

Standard and Reverse Shift Options

The B001 is configured for standard (road-pattern) gear shift operation, while the B001R offers reverse shift — the configuration preferred by many track riders and mandatory in some racing regulations. Both variants are otherwise mechanically identical and can be installed without modification to the motorcycle's chassis or electrical systems.
