Machined from aerospace-grade aluminium and proven on circuits across Italy, the Bonamici Racing Brake Lever Guard EVO LPRR2 brings uncompromising build quality to your Kawasaki ZX-4 RR. Every edge, radius and mounting point has been CNC-milled to racing tolerances — this is not a cosmetic accessory, it is a precision-engineered component that earns its place whether you are pushing through traffic or pushing lap times at the track.
Key Features
- CNC-milled from high-grade aluminium billet — ultralight construction with exceptional rigidity that outlasts cast or stamped alternatives
- Aerodynamically contoured profile reduces turbulence at the handlebar while giving the Ninja a purposeful race-derived aesthetic
- Reliably prevents unintended brake lever activation caused by contact with gloves, stray hands or other riders in close-quarters situations
- Includes the dedicated ADL4R_U adapter for a perfect, play-free fit on the stock OEM handlebar — no machining or modifications required
- 100% Made in Italy under Bonamici Racing's motorsport quality standards, the same manufacturing process used for their competition-spec components
Craftsmanship and Materials
The EVO generation of Bonamici's lever guard range represents the pinnacle of what a bolt-on aluminium protector can be. The guard is produced on multi-axis CNC machining centres in Italy, giving each unit consistent wall thickness, precise thread engagement in the mounting bore and a finish that accepts anodising evenly across every surface. The result is a component that feels planted, looks factory-fitted and adds negligible mass to the handlebar assembly. Available in a range of anodised colours — black, blue, bronze, gold, green, orange, red and silver — it integrates cleanly with aftermarket levers and standard handlebar clamps alike.
On Road and on Track
At the racetrack, an inadvertent brake application during a lean can end a session or worse. The LPRR2 guard wraps the lever in a protective shroud that blocks rogue contact without interfering with your deliberate braking inputs. On the road, it provides the same reassurance in filtering, town riding and group situations. The aerodynamic shaping is not decorative: at speed it smooths airflow across the control cluster and marginally reduces the lever's exposure to buffeting. Plug-and-play installation via the ADL4R_U adapter means the guard is on and ready in minutes, with no permanent alterations to your ZX-4 RR.
Fitment and Compatibility
This listing is specifically configured for the Kawasaki ZX-4 RR, model years 2023 to 2026, using the included ADL4R_U adapter. It mounts directly to the OEM handlebar on the right-hand (brake) side. No cutting, drilling or bar-end modification is required.
