RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
RCB SP800 Alloy Sport Rim Set is a premium, lightweight wheel upgrade designed engineered specifically for the Yamaha Aerox 155 / NVX 155.
Featuring an aggressive 8-spoke design, the SP800 balances striking street styling with high-level structural technology. This setup features a wide 2.50 x 14-inch Front and a massive 3.50 x 14-inch Rear configuration, allowing you to maximize tyre contact patches for improved cornering stability without altering your maxi-scooter’s signature low-slung, wide-stance profile.
Key Features
T6 Structural Heat Treatment: Cast from premium aluminum alloy and subjected to rigid T6 heat treating. This specialized process dramatically alters the metal’s molecular strength, creating an incredibly rigid rim capable of swallowing harsh pothole impacts without cracking or buckling.
Through-Hub Weight Reduction: The internal hub core is engineered with a hollowed, structural “through-hub” layout. By strategically removing excess unsprung mass from the wheel center, it decreases rotational inertia to unlock cleaner throttle response and greater fuel efficiency.
Curb-Profile Spoke Engineering: The 8 spokes are sculpted with a specialized curved curb profile. This specific geometry distributes lateral load more evenly across the wheel circumference, resisting spoke flexing during hard cornering and heavily loaded braking phases.
High-Durability Paint Finish: Coated in premium, chip-resistant paint formulations designed to withstand flying track debris, stone strikes, and harsh chemicals. It features an authentic, premium CNC-machined RCB Diamond Cut Logo on the rim edge.
True Tubeless Setup: Fully engineered for modern tubeless tires, eliminating the weight, heat build-up, and sudden deflation dangers associated with inner tubes.

Performance Advantage
The Aerox 155 is celebrated for its sportbike-inspired handling in a scooter format. RCB SP800 Rim Set amplifies this behavior by dropping unsprung weight. Less weight at the wheels means your front forks and rear dual shock absorbers can react faster to road surface imperfections, keeping your tires pressed firmly into the asphalt. The wide 2.50 and 3.50 wheel beds give high-performance sport tires a more rounded, progressive profile, allowing for faster lean-in transitions and predictable trail-braking control.
Installation Guidelines
Re-use or Replace Brake Disc Hardware: These wheels are a direct bolt-on match for your Aerox’s original brake rotor layout and speed sensor rings. When switching over your brake discs, always apply a fresh drop of medium-strength threadlocker to the mounting bolts.
Inspect Wheel Bearings & Oil Seals: The kit typically comes pre-installed with premium, high-speed wheel bearings and protective rubber dust seals. Always verify they are packed adequately with waterproof grease before final axle slide-in.
Check Tire Bead Lubrication: When mounting new tubeless tires onto these alloy rims, ensure the technician utilizes proper tire mounting paste or soapy water. Forcing a dry tire over the lip can scratch the premium anodized rim finish or damage the inner tire bead, resulting in slow, frustrating air leaks.
Torque Wheel Axle to OEM Specs: Always use a calibrated torque wrench to tighten your front axle bolt and rear axle nut to Yamaha’s strict factory specifications. Over-tightening can bind the internal wheel spacers, destroying the new bearings prematurely.
