GBRacing Engine Cover Protector Complete Set – Aprilia RSV4 / RR / 1100 Factory (2021–2024)

Designed for riders who demand protection that fits as precisely as it performs, the GBRacing Engine Cover Protector Complete Set wraps the most vulnerable covers on your Aprilia RSV4, RR and 1100 Factory in 60% glass-fibre reinforced nylon — a material chosen specifically for its ability to absorb and disperse impact energy without shattering. Whether you are commuting, touring or pushing hard on track days, this kit installs cleanly, sits flush, and stays put exactly where the bike needs it most.

Key Features

• 60% glass-fibre nylon construction delivers exceptional rigidity and impact resistance without adding unnecessary bulk to your engine cases.
• Bolt-on fitment replaces adhesive mounting entirely, so installation is straightforward and future replacement requires no surface preparation or residue removal.
• Precision-moulded to the exact geometry of the RSV4, RR and 1100 Factory engine cases — no trimming, no shimming, no compromise on fit.
• Complete set covers both the alternator and clutch sides in a single purchase, eliminating the guesswork of sourcing individual protectors separately.
• All mounting hardware is included in the box, so you can fit the kit the day it arrives without a trip to the fastener drawer.
• Reduces the real-world cost of a low-speed drop by shielding the covers most likely to crack on contact with tarmac or a kerb.

Build Quality and Design

GBRacing has built its reputation supplying protectors to race teams where weight, strength and fitment tolerances are non-negotiable. The 60% glass-fibre nylon compound used here is the same category of material you will find on race-prepared machines: stiff enough to resist deformation under load, yet with enough give to manage the energy of a slide rather than transferring it directly to the underlying cover. The bolt-on design keeps the protector anchored firmly — there is no risk of peel-back at speed or in warm conditions, a limitation that adhesive-only solutions can suffer from over time.

Road and Track Use

On the road, the set adds a reassuring layer of security for urban riding where kerbs, debris and slow-speed tip-overs are genuine risks. On track, it is effectively a requirement: a single get-off without engine cover protection can write off components that cost multiples of what this kit is worth. The EC-RSV4-2021-SET-GBR is engineered to complement the RSV4 platform's performance character — sitting low-profile so that neither airflow nor ergonomics are affected during spirited riding.
