Description
FEATURES
- The steel used in the EBC rotor blades is a special stainless blend with higher friction effect than normal heat treated stainless steel found on stock discs
- Boasts up to 10% improvement in friction effect improving brakes even further
- Weight of the X and XC series is reduced by 5-10% by using a 6 only button drive system on a lightweight alloy center hub, which once again grabs the lead over stock parts
- The SD-System uses a square sided rivet with many advantages
- The SD-System of square sided buttons means that the rotor can expand inwards and outwards unrestrained and that perfect rotor functionality is retained at any speed or load
- This extends the lifetime of the rotor and prevents distortion failures
- Keeps the rotor blades perfectly true and flat throughout their life cycle and technically the only reason for a rotor to need replacement will be impact damage or over a very extended number of miles possible rotor wear limits being exceeded
- This means that a rotor equipped with the EBC Brakes SD-System could last 5-10 times as long as a conventional rotor built with circular buttons
- The drive forces under braking are transmitted over a line contact on the square side of the button compared to the point contact of a circular button
- Two (2) Sets of Rotors Required

Vehicle Information
Aprilia RS 660 Motorcycle - Street (2021-2026)
The Aprilia RS 660, a performance sportbike, was introduced for the 2021 model year and is available through 2026. Powered by a 659cc liquid-cooled parallel-twin engine, it offers a balance of power and agility, positioning it as a versatile option for both road and track. Over the years, the RS 660 has seen significant evolutions. From 2021 to 2024, it produced 100 hp. Starting in 2025, horsepower increased to 105 hp, thanks to revisions for Euro 5+ compliance, including larger 52mm throttle bodies and a redesigned exhaust system. The 2025 and 2026 models also benefited from aerodynamic enhancements with integrated winglets, an updated electronics suite (new 5-inch TFT display, backlit controls, launch control), and a raised rev limiter. Regarding trims, the Standard model is available from 2021 to 2026. The lightweight-focused Extrema trim was introduced in 2023 and was available in 2024. For 2025 and 2026, the Factory trim was launched, distinguished by its fully adjustable Öhlins suspension and exclusive graphics. Q: How can I ensure the part fits my Aprilia RS 660?
