Get the Combo set for the ultimate brake system upgrade.
The RCB S5 Alloy Side Mirror is a high-definition rearview upgrade that combines premium materials with strict safety compliance. The E9 Standard designation indicates that these mirrors meet European safety certifications for reflective surface area and glass quality, ensuring a wide, distortion-free field of vision.
Designed with a sleek, angular profile, the S5 is an ideal aesthetic match for modern street bikes like the Yamaha MT-15, XSR 155, and other pipe handle mounts.
Key Features
-
Full Alloy Construction: Unlike standard plastic mirrors that vibrate and blur at high speeds, the S5 is constructed from high-grade aluminum alloy. This rigidity ensures a steady, “shake-free” image even at high RPMs.
-
E9 Certified Safety Glass: The mirror features high-quality convex glass that meets E-mark (E9) standards. This provides a wider viewing angle compared to flat glass, significantly reducing blind spots.
-
Anti-Glare Tinting: The glass is treated with a subtle blue or smoke anti-glare coating, which helps reduce the blinding reflection from the headlights of vehicles behind you during night riding.
-
360-Degree Adjustability: Equipped with a precision ball-joint mechanism, the S5 allows for fine-tuned horizontal and vertical adjustments to suit the rider’s height and seating position.
-
Aerodynamic Profile: The “stealth” shape is designed to minimize wind resistance, preventing the mirrors from “folding in” due to wind pressure at highway speeds.

Why Choose the RCB S5 Series?
-
Eliminate Vibration: Stock mirrors on single-cylinder bikes like the GSX-R150 or MT-15 often become useless above 7,000 RPM due to vibration. The heavy-duty alloy stem of the S5 dampens these vibrations for a crystal-clear view.
-
Premium Build Quality: The anodized finish is designed to resist “pitting” and corrosion caused by rain and road salt, keeping the mirrors looking new for years.
-
Legal Compliance: Because they meet the E9 standard for surface area, these mirrors are street-legal and provide the safety coverage required for urban commuting and touring.
Installation Note
The RCB S5 set typically includes 10mm right-hand and left-hand thread adapters. This is particularly important for Yamaha owners, as Yamaha motorcycles use a reverse thread (clockwise to loosen) on the right-side mirror mount. Ensure you select the correct adapter during installation to avoid stripping the threads on your master cylinder or mirror perch.
