DescriptionThe whole story

Machined to exacting Italian standards, the Spider Racing sprocket cover for the Aprilia RS 660 brings a level of material quality and finish that the factory cover simply cannot match. CNC-milled from premium-grade materials and manufactured entirely in Italy, it shields the front sprocket from road debris, chain lube overspray and grime while giving the drivetrain area a genuinely purposeful, race-inspired appearance.

Key Features

  • CNC-machined construction from high-grade materials, delivering a precise fit and the kind of long-term durability that bolt-and-forget replacements rarely achieve.
  • 100% Made in Italy — designed and produced at Spider Racing's facility with the attention to detail expected from a specialist Italian manufacturer.
  • Effective protection for the front sprocket against dirt, dust and road debris, reducing drivetrain wear in everyday and track use.
  • Lightweight build that adds no meaningful weight penalty to the motorcycle.
  • All necessary fixing hardware is included, making installation straightforward with no additional parts required.
  • Styled to complement the aggressive aesthetic of the Aprilia RS 660 rather than simply replacing a functional component.

Build Quality and Materials

Spider Racing's reputation is built on precision CNC machining and an uncompromising approach to material selection. The 90.A237 sprocket cover reflects that philosophy: every surface is machined to tight tolerances, the edges are clean, and the fitment against the RS 660 frame is flush and rattle-free. Where OEM covers often rely on moulded plastic, this Spider Racing unit is constructed with the robustness appropriate for a machine used hard on both road and circuit.
