IMA Special Parts Racing Top Clamp for Yamaha YZF-R6 RJ27 (2017–2026)

Engineered specifically for the Yamaha YZF-R6 RJ27 and optimised using finite element method (FEM) analysis, the IMA Special Parts Racing top clamp delivers the rigidity, precision and front-end feedback that competitive riding demands. Whether you are chasing lap times at the circuit or pushing hard on a track day, this clamp transforms how the R6 communicates through every corner and braking zone.

Key Features

• FEM-calculated construction maximises chassis rigidity and overall vehicle control, reducing flex under hard braking and aggressive turn-in.
• 7075 Ergal aluminium alloy keeps weight to an absolute minimum without compromising structural integrity — one of the highest strength-to-weight ratios available in aluminium.
• Adjustable offset from 24 mm to 32 mm allows precise geometry tuning to suit different circuits, rider styles and tyre compounds.
• Titanium fasteners throughout reduce unsprung and rotating mass while offering outstanding corrosion resistance for long service life.
• Improved braking stability and direct front-wheel feedback translate into earlier, more confident turn-in and cleaner lines through every corner.
• Precision-machined fitment designed exclusively for the RJ27 generation, ensuring a factory-quality installation with no modifications required.

Performance on Track

The IMA Special Parts Racing top clamp was developed from the ground up for racing use on the Yamaha YZF-R6 RJ27. By applying FEM optimisation during the design phase, IMA identified and eliminated flexion points that rob the standard clamp of rigidity. The result is a steering head assembly that transmits front tyre information to the rider with far greater clarity, allowing you to feel exactly where the limit is under braking and throughout the corner.

The variable offset range of 24 mm to 32 mm gives you real suspension geometry control. A shorter offset quickens the steering and increases stability under braking; a longer offset slows the steering slightly for smoother, flowing tracks. Combined with fork height adjustment, this clamp gives you a meaningful additional tuning variable that the standard component simply cannot provide.

Materials and Construction

The clamp body is machined from 7075 Ergal aluminium, the same high-performance alloy used in aerospace and professional motorsport applications. Its elevated tensile strength means the clamp resists the torsional loads generated under aggressive braking and cornering far better than standard 6061 alloy parts. The titanium fasteners that secure the clamp are chosen for the same philosophy: maximum strength, minimum mass, and zero compromise on longevity.
