Engineered and manufactured entirely in Italy to the most exacting standards, the Bonamici Racing LB140 adjustable brake lever delivers race-proven safety and precision ergonomics for the Yamaha YZF-R1 across every model year from 2004 to 2014. Its folding mechanism is not a cosmetic feature — it is a genuine crash-protection design that deflects on impact rather than snapping, protecting both the lever and the rider's confidence on track or road.

Key Features

  • Folding design pivots safely on impact, dramatically reducing the chance of lever breakage during a crash or tip-over — a genuine safety advantage over fixed levers.
  • Continuously adjustable reach lets you dial in the exact finger-to-lever gap to suit your hand size and riding style, improving feel and reducing fatigue on long runs or track sessions.
  • Precision-machined from high-strength aluminium alloy for an outstanding strength-to-weight ratio that stands up to the stress of repeated hard braking.
  • Direct OEM-replacement fitment, designed specifically for the YZF-R1 (2004-2014) — no drilling, no adapters, no guesswork.
  • Available in eight anodised colours — black, silver, gold, orange, red, green, blue, and bronze — so you can coordinate with your existing livery without compromising quality.
  • 100% Made in Italy under Bonamici Racing's strict quality-control process, the same manufacturing philosophy trusted by professional racing teams.

Safety-Led Design

The folding pivot is the most important safety detail on this lever. When a conventional rigid lever meets the tarmac in a fall, it snaps — often leaving the rider unable to brake. The LB140's folding joint absorbs the rotational force and folds the lever clear, so it returns to its operating position once the bike is righted. This design is standard practice in top-level motorsport and is precisely why Bonamici Racing carry it over into their road and track aftermarket levers.

The continuously adjustable span means the lever can be set in seconds without tools, allowing riders to move between track and road configurations or share the bike between differently-sized riders. Correct reach is not just a comfort detail — it ensures the braking finger applies force at the optimum angle, which reduces hand-pump during endurance riding and gives sharper, more consistent modulation.

Construction & Materials

The LB140 is CNC-machined from high-strength aluminium alloy — a material choice that keeps lever weight to a minimum while maintaining the rigidity needed for precise brake actuation. The anodised finish is applied after machining, giving a hard, corrosion-resistant surface that retains its colour under UV exposure and repeated cleaning. Every lever leaves the Italian facility having passed dimensional and functional checks; Bonamici Racing does not outsource production or quality control.
