Bonamici Racing SM51 Race Handlebar for Aprilia RSV4 / Factory / R / RR / RF (2009–2016)

Machined from aerospace-grade Ergal 70/75 aluminium and finished to exacting tolerances in Italy, the Bonamici Racing SM51 race handlebar transforms the ergonomics of the Aprilia RSV4, Factory, R, RR and RF without compromise. A 15 mm rise paired with a 6.5° downward sweep places your hands in a sharper, more committed position — reducing fatigue on long stints while sharpening steering response when you need it most.

Key Features

• Precision CNC-milled from Ergal 70/75 aluminium for outstanding rigidity and long-term durability
• 15 mm rise and 6.5° downward tilt optimise rider posture and improve steering precision across all conditions
• Four-point mounting system — two points at the handlebar, two at the forks — guarantees a rock-solid, vibration-resistant installation
• Integrated anti-slip safety system provides consistent grip and stability even under extreme riding loads
• Model-specific engineering ensures a perfect, no-modification fit for all RSV4 variants from 2009 to 2016
• 100% designed and manufactured in Italy to Bonamici Racing's competition standards

Premium Construction

Ergal 70/75 is a high-strength aluminium alloy drawn directly from aerospace engineering — the same material family trusted in MotoGP and World Superbike paddocks. Bonamici Racing subjects every SM51 bar to full CNC milling rather than casting, eliminating porosity and delivering consistent wall thickness throughout. The result is a handlebar that absorbs track-level stress cycles without flexing or fatiguing in the way that lesser alloys would over time.

Ergonomics and Control

The SM51's geometry is not a compromise between road and track — it is a deliberate race specification. The 15 mm rise lifts the bar enough to relieve pressure on wrists during extended sessions, while the 6.5° downward sweep keeps weight over the front wheel where a superbike like the RSV4 demands it. The net effect is improved feedback through the bars, quicker direction changes, and a more natural arm position when tucked behind the fairing.

Anti-Slip Safety System

Bonamici's proprietary anti-slip feature is machined directly into the clamp interface, preventing any rotational movement under braking or cornering forces. Combined with the four-point mounting arrangement — dual clamp points on the bar itself and two further anchor points at the fork tops — the SM51 stays precisely where you set it, lap after lap.

Fitment and Compatibility

The SM51 is engineered exclusively for the following models:

• Aprilia RSV4 (2009–2016)
• Aprilia RSV4 Factory (2009–2016)
• Aprilia RSV4 R (2009–2016)
• Aprilia RSV4 RR (2009–2016)
• Aprilia RSV4 RF (2009–2016)

No modifications are required for fitment on any of these variants. Always verify your specific model year before installation.
