DescriptionThe whole story

Engineered for riders who demand all-day comfort without sacrificing a razor-sharp riding position, the Bonamici Racing SM47 race handlebar transforms the ergonomics of the Yamaha YZF-R3. A 15 mm rise combined with a 6.5° downward sweep places your hands and upper body in a naturally aggressive yet sustainable posture — eliminating the fatigue that kills focus on long track days or spirited road rides.

Key Features

  • 15 mm rise and 6.5° downward inclination optimise upper-body posture for reduced fatigue and sustained control
  • CNC-machined from Ergal 70/75 high-strength aluminium alloy for an exceptional strength-to-weight ratio and lasting durability
  • Integrated anti-slip safety system provides consistent grip and stability across all riding conditions
  • Four-point mounting system — two points at the handlebar and two at the fork — ensures a rock-solid, rattle-free installation
  • Precision fitment designed exclusively for the Yamaha YZF-R3 (2019-2026)
  • 100% Made in Italy to Bonamici Racing's exacting manufacturing standards

Ergonomics and All-Day Comfort

The geometry of the SM47 is not an afterthought — it is the product of extensive track testing. The 15 mm rise lifts the bar relative to the standard clip-on position, reducing the weight borne by your wrists on longer stints, while the 6.5° downward sweep keeps your elbows in a relaxed, bent position that feeds back precise road feel without tensing your shoulders. Whether you are riding circuit sessions back to back or covering distance on the road, the difference is tangible within the first few kilometres.

Construction and Materials

Bonamici Racing mills the SM47 from Ergal 70/75, an aerospace-grade aluminium alloy chosen for its high tensile strength and resistance to flex under load. Every surface is CNC-machined to tight tolerances, so the bar interfaces perfectly with your yokes and fork tops without shimming or improvisation. The integrated anti-slip safety system is machined directly into the bar ends, maintaining grip security even under hard braking or vibration. Italian manufacture means each unit is inspected before it leaves the facility.

Fitment and Compatibility

The Bonamici Racing SM47 handlebar is designed and manufactured specifically for the following model:

  • Yamaha YZF-R3 (2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026)

The four-point mounting configuration — two fixings at the handlebar clamps and two at the fork tops — replicates OEM mounting geometry precisely, making installation straightforward with standard workshop tools.
