DescriptionThe whole story▼
The Bonamici Racing SM50B handlebar is a masterclass in Italian craftsmanship — CNC-machined from Ergal 70/75 aerospace-grade aluminium and engineered exclusively for the Yamaha YZF-R1/M across all RN32, RN49 and RN65 generations from 2015 to 2026. Its raised, forward-inclined geometry — 15 mm rise with a 6.5° downward angle — delivers the kind of precise, confidence-inspiring steering feel that defines Bonamici's racing heritage.
Key Features
- CNC-machined from Ergal 70/75 high-strength aluminium alloy for an exceptional strength-to-weight ratio that undercuts most OEM handlebars.
- Optimised geometry: 15 mm rise and 6.5° downward inclination improve ergonomics and sharpen steering precision on both road and circuit.
- Anti-slip safety system provides additional grip and stability under hard cornering and extreme riding conditions.
- Four-point mounting system — two clamp points at the handlebar and two at the fork — ensures a rigid, rattle-free installation.
- Complete kit includes washers and 250 mm handlebar tubes for a straightforward, tool-friendly fitment.
- 100% Made in Italy, reflecting Bonamici Racing's uncompromising production standards.
Design, Finish and Heritage
Bonamici Racing has built its reputation supplying components to professional Superbike and World Endurance teams, and the SM50B carries that lineage into a direct-fit road and track upgrade. The clean, machined aluminium aesthetic is a statement in itself — no unnecessary bulk, no superfluous lines. Every surface is the product of multi-axis CNC milling from a solid billet of Ergal 70/75, an alloy selected for its outstanding fatigue resistance and dimensional stability under the sustained loads of performance riding. The result is a handlebar that looks as purposeful as it performs, integrating seamlessly with the aggressive stance of the R1 and R1M.
Performance and Ergonomics
The SM50B's geometry was developed with the YZF-R1 platform specifically in mind. The 15 mm rise lifts the rider's hands slightly compared to the OEM unit, reducing wrist strain on longer outings without sacrificing the committed, low-crouch position the R1 demands. The 6.5° downward angle simultaneously keeps weight over the front wheel for neutral, predictable turn-in — a balance that translates directly to lap time on circuit and composure on a fast road. The anti-slip system ensures the grip stays exactly where you set it, however hard the riding becomes.
