DescriptionThe whole story▼

Engineered specifically for the Yamaha YZF-R1/M across the RN32, RN49 and RN65 generations (2015–2026), the IMA Special Parts Racing top clamp is a precision-optimised fork bridge developed through advanced FEM (Finite Element Method) analysis — delivering structural integrity and handling confidence you can trust at race pace and beyond.

Key Features

  • FEM-calculated construction ensures every gram of material is placed where it matters, maximising structural rigidity while eliminating unnecessary mass.
  • Machined from 7075 Ergal aluminium — a high-strength aerospace-grade alloy used in top-level motorsport for its exceptional strength-to-weight ratio.
  • Adjustable offset from 24 mm to 32 mm allows precise chassis geometry tuning to suit individual riding styles and circuit conditions.
  • Improved braking stability and front-end feedback give riders the confidence to brake deeper and carry more corner speed.
  • Titanium hardware throughout — ultralight, corrosion-resistant and rated for the extreme loads of competitive motorcycle racing.
  • Available in three finishes: black, titanium and aluminium, allowing integration with a wide range of race liveries and street setups.

Precision Engineering for the Track

The IMA Special Parts Racing top clamp is not a cosmetic upgrade — it is a geometry component built to a genuine racing specification. The FEM optimisation process maps load distribution across the entire clamp under braking, cornering and combined forces, resulting in a part that is stiffer where stiffness is needed and precisely weighted to contribute to overall unsprung and front-end mass reduction.

The 7075 Ergal aluminium billet construction gives this clamp a rigidity profile that directly translates into more accurate steering inputs. Riders upgrading from the OEM unit consistently report sharper turn-in, reduced front-end vagueness under trail braking, and improved grip feedback through the bars — all critical advantages when lap times matter.

Adjustable Offset: Dial In Your Geometry

One of the defining advantages of this clamp over standard equipment is the adjustable offset range of 24 mm to 32 mm. This allows the trail and steering geometry of the Yamaha YZF-R1/M to be fine-tuned without changing forks or head angle, offering a level of setup flexibility previously reserved for full factory race teams. Whether you need a sharper, more aggressive front end for technical circuits or a more stable configuration for high-speed tracks, the offset can be set to match.

Titanium Hardware

Every fastener supplied with the IMA Special Parts Racing top clamp is manufactured from titanium. Titanium bolts offer a significant weight saving over steel hardware while providing corrosion resistance and fatigue strength appropriate for the dynamic loads experienced in racing. This attention to detail throughout the component reflects IMA Special Parts' commitment to a complete racing-grade solution rather than a compromise.
