GBRacing Alternator Cover Protector for Aprilia RSV4 / 1100 Factory / R / RR / RF (2009–2020)

Born on the circuit and built to last on the road, the GBRacing alternator cover protector brings genuine motorsport pedigree to your Aprilia RSV4. Trusted by professional race teams the world over, this cover marries an aggressive, purposeful aesthetic with the kind of structural integrity that only a 60% glass-fibre reinforced high-impact nylon compound can deliver.

Key Features

• Precision fitment for the Aprilia RSV4, RSV4 1100 Factory, R, RR and RF across all model years from 2009 to 2020
• Revolutionary high-impact composite material — 60% glass-fibre reinforced nylon — delivers exceptional crush resistance at minimal weight
• Bolt-on installation only: no adhesives, no guesswork, no compromised bond strength over time
• All required mounting hardware included straight out of the box
• Motorsport-derived design refined through real-world competition by professional teams globally
• Protects the alternator housing from crash damage that would otherwise demand a costly engine-out repair

Design, Finish and Heritage

GBRacing has spent years refining its engine cover protector range alongside professional race outfits, and that heritage shows in every detail of this alternator cover. The finish is clean and purposeful — no unnecessary bulk, no afterthought styling. The high-impact composite is moulded to follow the Aprilia's original cover contours precisely, so the protector sits flush and looks as though it belongs there from the factory.

Unlike budget alternatives that rely on adhesive pads, GBRacing engineers this cover to bolt directly to the engine using the supplied hardware. That means the fit is repeatable and secure whether you are fitting it fresh at home or re-installing it after a track-day inspection. The material itself is part of what sets GBRacing apart: the 60% glass-fibre loading gives the nylon compound a stiffness and energy-absorption profile that outperforms standard injection-moulded plastics in crash scenarios without adding perceptible weight to the machine.

On Track, On Road

A blown alternator cover can end a track day in minutes and turn a simple lowside into an engine replacement. This protector is the straightforward, cost-effective insurance policy for any Aprilia RSV4 owner who pushes their machine — whether that is a Sunday morning canyon run or a full track-day programme. Fit it once, inspect it periodically, and ride with the confidence that the damage stays superficial if the worst happens.
