Aprilia RSV4 and Tuono V4 Clear Clutch Cover, OAP-00100 STM

Description

Aprilia RSV4 and Tuono V4 Clear Clutch Cover (OAP-00100)

The Aprilia RSV4 and Tuono V4 Clear Clutch Cover is the definitive aesthetic and functional upgrade for the Aprilia V4. Designed and manufactured in Italy by STM, this cover allows you to showcase the mechanical “dance” of your clutch while offering the superior engineering that STM is known for in MotoGP and WorldSBK paddocks.

The Engineering Edge

• Billet Aluminum Construction: Each cover is CNC-machined from a solid block of high-grade aluminum, providing a high strength-to-weight ratio and a significant upgrade over the stock cast cover.
• Impact-Resistant Lexan Window: The clear porthole is made from thick, heat-treated Lexan that is resistant to both high engine temperatures and road debris, ensuring long-term clarity and safety.
• Enhanced Heat Dissipation: The machined aluminum body acts as a secondary heat sink, helping to pull heat away from the clutch assembly more effectively than the OEM plastic or cast units.
• Oil-Bath porthole Design: Specifically engineered for the Aprilia V4’s wet clutch system, the STM Transparent Oil Bath Porthole ensures a leak-free seal using competition-spec O-rings.

📊 Technical Specifications

🛡️ Why Upgrade to an STM Clear Cover?

1. Visual Diagnostics: A clear cover allows you to instantly inspect oil color and clutch health without removing a single bolt. You can see if your oil is darkening or if there is any abnormal debris in the system.
2. Symmetry & Style: It provides a “factory racer” look that perfectly complements other high-end upgrades like carbon fiber fairings or rearsets.
3. Mechanical Showcase: If you have installed an STM Slipper Clutch, this cover turns it into a centerpiece, revealing the precision-machined pressure plate and springs in motion.

❓ FAQ: Installation & Maintenance

Does this require a dry clutch conversion?

No. Unlike Ducati models, this STM cover is designed for the standard wet clutch (oil bath) system found on the Aprilia V4 engine.

Will the window “fog up” or turn yellow over time?

STM uses UV-resistant Lexan and a specialized ventilation path to minimize condensation. With proper installation and oil changes, the window remains clear for thousands of miles.

Is a new gasket required for installation?

While the STM cover uses high-quality O-rings, it is always recommended to use a fresh Aprilia OEM Clutch Cover Gasket to ensure a perfect, leak-free seal.

Is the pressure plate included?

No. The pressure plate is optional and sold separately.
