Alternator cover protector matt carbon Aprilia Tuono V4 (2025+)

Give your V4 more character and protection

• Visible carbon weave that follows the curve of the alternator cover
• Rigid prepreg carbon cured in several autoclave stages
• UV-resistant matt clear coat suits genuine matt Aprilia carbon
• Added protection in everyday use, a tip-over or a slide
• Model-specific, plug-and-play fit over the original cover

Sharp-looking carbon that follows the curve of your alternator cover. It gives this side of the Tuono the purposeful, high-end finish the V4 deserves. Look at the engine from the side and the effect is immediate. The weave follows the outline and draws your eye to a detail you might otherwise walk straight past.

The matt clear coat gives the weave depth with subdued reflections. You can see the pattern clearly up close. It looks clean and purposeful, as though the carbon belongs on the engine. It also complements genuine matt Aprilia accessories such as the carbon side panels.

The carbon fits over the original cover, giving the engine a new look and an extra layer of protection in one step. It helps reduce marks from flying stones and can help protect the original cover from damage if the bike tips over or slides.

A precise fit and a rigid carbon shell

Ilmberger uses carbon fibres that are already impregnated with resin. The layers are laid up in a mould and cured in several stages under heat and pressure in an autoclave. The result is a rigid shell that holds its shape and closely follows the curves of the original cover. Ilmberger has been making carbon parts for motorcycles since 1990. You can see that experience in the neatly finished edges and the fit over the original part.
