DescriptionThe whole story▼

Engineered from the ground up for the Aprilia RS 660, the IMA Special Parts Racing top clamp is a study in purposeful Italian-inspired precision — every curve and bore calculated using Finite Element Method (FEM) analysis to deliver uncompromising rigidity where it matters most. Machined from aerospace-grade 7075 Ergal aluminium and finished in your choice of anodised black, titanium or natural aluminium, it is as visually arresting as it is mechanically resolute.

Key Features

  • FEM-calculated construction ensures maximum torsional stiffness and consistent front-end response under hard braking and corner entry.
  • 7075 Ergal aluminium delivers an outstanding strength-to-weight ratio — high-tensile rigidity without unnecessary mass at the steering head.
  • Adjustable offset from 24 mm to 32 mm lets you dial in trail and steering weight to suit your riding style, track layout or tyre choice.
  • Titanium fasteners throughout reduce rotational unsprung mass and resist corrosion across season after season of use.
  • Improved braking stability and enhanced front-wheel feel translate directly into greater confidence when trail-braking into tight corners.
  • Three distinct anodised finishes — black, titanium and aluminium — give the cockpit a clean, race-shop aesthetic that complements the RS 660's factory lines.

Design, Finish and Heritage

IMA Special Parts has built its reputation supplying components to club racers and privateer teams who refuse to compromise on quality. This top clamp reflects that ethos: the anodised surfaces are uniform and deep-set, the machining tolerances are tight, and the overall silhouette is purposefully minimal — no superfluous material, no decorative flourishes that add weight without benefit. Whether finished in stealthy anodised black, the warm mid-tone of titanium or the classic look of natural brushed aluminium, the clamp integrates seamlessly with the RS 660's twin-spar frame aesthetic while signalling that the chassis setup beneath it has been taken seriously.

Performance on Road and Track

The adjustable offset range — 24 mm through 32 mm — is the clamp's most rider-focused feature. A shorter offset quickens the steering and sharpens turn-in response, ideal for tight technical circuits; a longer offset softens the steering geometry for stability at high speed or when running harder compound tyres. Combined with the inherent stiffness of the FEM-optimised aluminium billet, changes in feel are immediate and repeatable, making it straightforward to find a setup that works across a full race weekend or a long sport-touring day.
