Bonamici Racing Adjustable Folding Brake Lever for Suzuki GSX-R 1000 (2005-2023) LB090

Machined from high-strength aluminium and assembled entirely in Italy, the Bonamici Racing LB090 brake lever brings genuine race-grade hardware to every generation of the Suzuki GSX-R 1000 from 2005 through to 2023. The combination of stepless reach adjustment and a fold-away pivot makes this one of the most rider-focused upgrades available for the platform — whether you chase lap times or simply demand more from a Sunday morning blast.

Key Features

• Steplessly adjustable reach lets you dial in the precise finger distance that suits your hand size, glove preference and riding style without tools.
• Folding mechanism absorbs impact in a tip-over or low-side, pivoting clear rather than snapping — protecting both the lever and the master cylinder.
• Constructed from premium high-tensile aluminium: genuinely lightweight yet resistant to the flex and fatigue that lesser alloys exhibit under hard braking.
• Available in eight anodised finishes — black, silver, gold, orange, red, green, blue and bronze — so the lever integrates with any GSX-R colour scheme or aftermarket bodywork.
• Designed and manufactured 100% in Italy to Bonamici Racing's exacting quality standards, the same standards used on their full race-team hardware.
• Direct, application-specific fit for the Suzuki GSX-R 1000 across the full 2005-2023 model range with no modification required.

Build Quality and Materials

Bonamici Racing selects high-tensile aluminium alloy as the core material for the LB090 — a deliberate choice that prioritises stiffness-to-weight ratio over the cost savings of generic billet. The lever body is CNC-machined to tight tolerances, delivering a surface finish and dimensional consistency that you can feel the moment you squeeze it for the first time. The anodised colour layer is not a cosmetic afterthought; it provides a hard, corrosion-resistant barrier that holds up to chain lube, brake fluid splashes and the general grime of serious riding.

The folding joint is engineered to a specific release torque, meaning it stays rigid under normal braking loads but gives way cleanly under the sudden lateral force of a fall. Once you've righted the bike, the lever snaps back into position and you're ready to ride — no broken pivot, no scratched master cylinder body, no side-of-the-road drama.

On Road and on Track

The stepless reach adjuster is the detail that separates premium levers from catalogue fillers. Rather than three or five fixed positions, you can set the LB090 to exactly the distance your index or two-finger braking technique demands. Track riders switching between tyre-warming runs and race laps can fine-tune feel without changing lever position; road riders who swap between glove thicknesses in different seasons will appreciate the same freedom. The result is consistent, confident brake modulation — the kind that matters when you're trail-braking into a tight bend on cold morning roads or braking hard from high speed at a circuit.

Fitment and Compatibility

The Bonamici Racing LB090 is engineered specifically for the Suzuki GSX-R 1000 across the complete production span listed below. No adapters, no drilling and no master-cylinder modifications are required.
