DescriptionThe whole story▼

A practical, plug-and-play upgrade that pays for itself the first time your handlebar catches an obstacle — the Bonamici Racing LPRR_B brake lever guard gives your Kawasaki ZX-4 RR reliable protection against accidental brake activation, whether you are filtering through city traffic, pushing hard on a track day, or parked in a crowded paddock.

Key Features

  • Prevents unintended braking caused by external contact with the brake lever — a genuine everyday safety gain for road and track alike
  • Supplied with the dedicated ADL4R adapter, engineered to match the ZX-4 RR OEM handlebar for a precise, rattle-free fit straight out of the box
  • CNC-machined from aluminium for a weight-conscious, high-strength construction that resists knocks without adding bulk
  • Aerodynamic profile improves airflow at the handlebar end, contributing to stability at higher speeds on the open road or circuit
  • True plug-and-play installation — no modifications, no specialist tools, no additional parts required
  • 100% Made in Italy to Bonamici Racing's exacting production standards

Everyday Usability and Value

The LPRR_B is not purely a track accessory. In daily urban riding, the guard eliminates the nagging risk of a passing vehicle, bicycle, or pedestrian catching the brake lever and triggering an unintended stop. That peace of mind alone justifies the fitment, and the anodised aluminium finish means it will continue to look sharp through seasons of commuting and weekend rides alike. The included ADL4R adapter removes the guesswork from installation — simply bolt it to the stock handlebar and you are done.

Build Quality and Design

Bonamici Racing manufactures the LPRR_B from CNC-milled aluminium, a process that produces consistent wall thicknesses, tight tolerances, and a surface ready for anodising. The result is a guard that is genuinely light yet rigid enough to deflect meaningful impacts. The aerodynamic body shape is not purely cosmetic: at track-day velocities the form reduces turbulence at the bar end, keeping the front end feeling planted and composed. Available in eight anodised colours, the guard integrates with the ZX-4 RR's aggressive styling rather than clashing with it.
