Bonamici Racing Clutch Lever with Multiple Offsets – Yamaha YZF-R1/M (2004-2026)

Engineered in Italy to the exacting standards Bonamici Racing is known for, this aluminium clutch lever gives Yamaha YZF-R1 and YZF-R1M riders (2004–2026) genuine command over clutch feel. Choose from five distinct offsets and, if desired, a fully adjustable reach setting — all in a lever that is precision-machined to drop straight onto your bike without modification.

Key Features

• Five offset options (24, 27, 29, 32 and 34 mm) let you dial in clutch resistance from light and progressive through to firm and aggressive — tuned to your riding style, not a compromise.
• Choice between a fixed-position lever for consistent, repeatable feel and an adjustable lever that can be fine-tuned on the fly.
• Machined from high-strength aluminium throughout — no cast components — for an exceptional strength-to-weight ratio and long service life.
• Exact-fit design developed specifically for the Yamaha YZF-R1 and YZF-R1M across every generation from 2004 to 2026, ensuring correct geometry and safe, secure installation.
• 100% Made in Italy under Bonamici Racing's stringent quality controls, the same standards applied to their WorldSBK and track-day components.

Choosing Your Offset

The offset figure determines the mechanical advantage — and therefore the perceived weight — of the clutch pull. Here is a straightforward guide to help you select the right value:

• Offset 24: The lightest clutch action available in this range. Ideal for riders who prefer an effortless, low-resistance pull, particularly on long rides or in stop-and-go traffic.
• Offset 27: A modest step up in resistance for more precise modulation, well suited to riders who want a balance between comfort and control.
• Offset 29: The neutral midpoint of the range, combining everyday comfort with confident clutch control. A strong choice for riders covering both road and track.
• Offset 32: Noticeably firmer feel, preferred by sport-oriented riders who want a more direct, responsive clutch engagement.
• Offset 34: Maximum resistance — for riders who demand an aggressive, high-feedback clutch action and carry corner speed with confidence.

Fixed or Adjustable?

The non-adjustable lever maintains a single, consistent reach position — once set up correctly for your hand size, it delivers repeatable feel lap after lap. The adjustable variant features an on-the-fly reach adjuster so you can alter hand position without tools, making it the natural choice for riders who share the bike or who change glove thickness between road and track use.

Build Quality

Every lever in Bonamici Racing's range is machined from solid high-strength aluminium billet in their Italian facility. The result is a component free of the porosity and inconsistency that casting can introduce — one that resists fatigue, handles repeated track use without deformation, and retains its surface finish far longer than OEM alternatives. The precision-machined pivot interface ensures smooth, consistent lever action from the first pull to the thousandth.

Fitment and Compatibility

This clutch lever is designed and manufactured exclusively for the Yamaha YZF-R1 and YZF-R1M, covering all model years from 2004 through to 2026. It fits both the standard YZF-R1 and the factory-spec YZF-R1M variant without any adaptation or additional hardware.
