Aprilia RSV4/Tuono V4 Brake Lever Guard – PLF08 DBK

Aprilia RSV4/Tuono V4 Brake Lever Guard

The DBK Special Parts Aprilia RSV4/Tuono V4 Brake Lever Guard (Part# PLF08) is a vital safety component designed for the high-speed environment of the Aprilia RSV4 and Tuono V4. Unlike universal guards that require sloppy expansion sleeves, the PLF08 features a dedicated mounting system that integrates seamlessly with the Aprilia’s internal handlebar architecture, ensuring a rock-solid fit that won’t rotate or vibrate loose under extreme conditions. Originally developed for MotoGP to prevent accidental brake engagement during close-quarters racing, this guard is now a mandatory requirement for most track-day organizations and a premium safety addition for spirited street riding.

Track-certified safety, Italian-designed precision. 

The DBK Technical Edge

• 7075-T6 Ergal Construction: The main guard arm is CNC-machined from a single block of high-tensile aluminum. This material is chosen for its rigidity; it won’t flex inward toward the lever during a collision, providing a true protective barrier.
• Aerodynamic Deflector Tip: The tip of the guard is shaped to minimize aerodynamic drag at high speeds. This prevents the “wind-brake” effect where air pressure can inadvertently pull the brake lever at speeds exceeding 150 mph.
• Adjustable Length: The guard features a sliding adjustment system, allowing you to perfectly align the guard with the length of your OEM or aftermarket (DBK/Brembo) levers.
• Vibrant Anodized Finish: Available in Black, Red, Gold, Blue and Silver. The hard-anodized surface is resistant to sunlight, sweat, and brake fluid, maintaining its deep luster season after season.

🛡️ Why Install the PLF08 Guard?

1. Critical Safety: In a “group-start” or lane-splitting scenario, a simple bump from another rider’s shoulder or a vehicle’s side mirror can lock the front wheel instantly, leading to an immediate “endo” or crash. This guard eliminates that risk.
2. Handlebar Protection: In the event of a low-side slide, the lever guard often acts as the primary contact point, sacrificing itself to save your expensive master cylinder and brake lever.
3. The MotoGP Aesthetic: It provides an instant visual upgrade, giving your Aprilia the aggressive, purposeful look of a factory-team race bike.

❓ FAQ: Tech Support

Does this require any drilling?

No. The PLF08 is designed to thread directly into the Aprilia’s factory handlebar mounting point. Simply remove the original bar-end weight and install the guard.

Can I still use my bar-end mirrors?

No. Because this guard occupies the bar-end mounting point, it is not compatible with bar-end mirrors. It is designed for riders prioritizing safety and track-readiness.

Is it compatible with Brembo RCS master cylinders?

Yes. The guard is adjustable in length and can be positioned to clear any aftermarket master cylinder and lever setup.

Pro-Tip for Your Shop: Riders who track their RSV4 almost always buy the matching DBK Clutch Lever Guard or a matching set of Adjustable Folding Levers.
