DescriptionThe whole story▼
The Bonamici Racing SM50 clip-on handlebar is engineered to meet the exacting safety and performance standards demanded by the Yamaha YZF-R1 across its 2003–2014 generation. Built in Italy from aerospace-grade Ergal 70/75 aluminium and CNC-machined to tight tolerances, the SM50 delivers a certified anti-slip retention system and a four-point mounting arrangement — two at the handlebar and two at the fork — so the bar stays locked under the hardest braking and the sharpest direction changes. If rider safety and structural integrity matter as much to you as lap times, this is where to start.
Key Features
- Integrated anti-slip safety system locks bar position under extreme load, adding a measurable layer of security over standard clip-ons.
- Four-point mounting configuration — two handlebar clamp points plus two fork mounting points — distributes stress evenly and eliminates unwanted flex.
- 15 mm rise paired with a 6.5° downward sweep refines ergonomics without compromising the aggressive, forward-biased posture of the R1.
- Ergal 70/75 aerospace aluminium construction provides an exceptional strength-to-weight ratio and long-term corrosion resistance.
- Full CNC machining ensures dimensional accuracy on every unit — no casting porosity, no soft spots.
- 100% Made in Italy, designed exclusively for the Yamaha YZF-R1 2003–2014 for a precise, no-modification fitment.
Design and Construction
Ergal 70/75 is the same high-strength aluminium alloy series relied upon in motorsport and aerospace applications. Its combination of tensile strength and low mass makes it the material of choice when a component must absorb repeated dynamic loads without fatiguing. Bonamici Racing machines each SM50 from solid billet stock using CNC technology, so tolerances are held precisely across every production unit. The result is a handlebar that maintains its geometry and clamping integrity season after season, whether the bike sees weekend track days or regular road riding.
Safety and Stability
The integrated anti-slip safety system is a defining feature of the SM50 and the primary reason to choose it over lesser alternatives. Under hard deceleration or mid-corner inputs, a bar that rotates even fractionally in its clamp introduces an unpredictable variable. Bonamici's anti-slip design prevents any rotational movement, keeping rider inputs translating directly and predictably to the front wheel at all times. Combined with the four-point mounting system, the SM50 provides a level of structural security that riders who push their R1 hard will notice immediately.
Fitment and Compatibility
The SM50 is designed and manufactured specifically for the following fitment:
- Yamaha YZF-R1 — model years 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014
No modification or adaption is required. Always verify your exact model year and specification before fitting.
