Upgrade your maxi-scooter’s braking ergonomics, safety functionality, and handlebar styling with the RCB S3 Alloy Brake Lever Set. Precision-engineered for the Yamaha NVX 155 and Aerox 155 platforms, this premium dual-lever kit integrates an ultra-convenient mechanical parking brake stopper system alongside fine-tune adjustable ergonomics.

By replacing soft, flex-prone factory cast levers with high-tensile billet structures, this setup provides a crisp, predictable brake bite point and essential roll-away protection when parking on inclines.

Key Features

Mechanical Parking Brake Stopper

• Anti-Roll Incline Security: Includes a specialized structural alloy locking plate that mounts contextually to the rear brake assembly side. When engaged, it acts as a reliable parking brake, locking the rear wheel to prevent your scooter from rolling off its side stand or center stand when parked on slopes.

• One-Handed Quick Release: Designed for simple, intuitive real-world operation—simply pull the brake lever in and flip the mechanical stopper to lock it, then just squeeze the lever again to instantly disengage the lock and ride.

Premium S3 Ergonomics & Adjustability

• CNC-Machined Billet Aluminum: Precision-milled from high-grade solid aluminum blocks, offering immense rigidity under hard emergency braking and excellent durability over cast OEM alternatives.

• Toolless Reach Adjustment: Features an integrated, smooth-turning adjustment knob mounted directly on the lever body. This allows you to quickly adjust the distance between the handlebar grip and the lever to match your hand size or glove thickness.

• Ergonomic Curve Profile: Formed with a smooth, contoured finger path that distributes pressure evenly across your fingers, reducing hand cramping and forearm fatigue during heavy urban filtering or extended traffic commuting.

• Anodized Finish & Fold Resistance: Coated with a premium anodized exterior layer that prevents paint chipping and UV fading, featuring an engineered structural point designed to minimize master cylinder damage in a minor tip-over.

Technical Specifications

Installation Guidelines:

This lever set mounts directly into your factory perches using your stock pivot bolts. When installing the left-side lever, align the specialized parking stopper plate assembly carefully with the lever bracket before tightening the pivot pin. Test that both the front brake micro-switch and rear brake safety-start switches activate flawlessly before hitting the road.

Why Choose This?

1. Essential Scooter Parking Protection: Unlike standard manual motorcycles that can be left “in-gear” to lock the transmission on a hill, automatic CVT scooters will roll freely when turned off. The integrated S3 stopper solves this inherent layout flaw completely.

2. Eliminating Lever Flex: Factory levers are typically stamped or cast from soft pot metals that bend slightly when pulled hard, making your brakes feel spongy. The rigid billet alloy of the RCB S3 levers transmits your direct muscle force into the master cylinder with zero deflection.

3. Custom Cockpit Overhaul: Ditch the plain, bare-metal industrial look of your stock handlebar controls. This dual-lever kit refines your control area with aggressive mechanical styling and crisp anodized accents that look great alongside aftermarket grips or bar-end mirrors.
