Overview
The Losi High Bite Aluminum Front Brake Rotor with Screws is a premium brake component designed specifically for the Losi 1/4 scale Promoto-MX and Promoto-SM supermoto motorcycle models. This replacement part represents a genuine OEM upgrade from Losi, one of the most respected names in RC hobby racing and off-road vehicles. Whether you're a competitive racer looking to maintain peak braking performance or an enthusiast keen to upgrade your Promoto motorcycle, this high-quality brake rotor delivers the stopping power and durability you need for consistent, reliable performance on the track or trail.
Brake performance is absolutely critical in RC motorcycles, where precise control and rapid deceleration can mean the difference between victory and defeat. The High Bite design of this rotor means it's engineered to provide superior friction and braking force compared to standard rotors, giving you more confidence when entering corners at speed or making emergency stops. If you're serious about getting the best from your Losi 1/4 scale Promoto motorcycle RC model, this brake rotor upgrade is an essential part of your tuning arsenal. The aluminium construction ensures durability whilst keeping weight to a minimum, which is crucial for maintaining the ideal handling characteristics of your motorcycle-style RC vehicle.
This is a direct replacement part that comes complete with all necessary screws for installation, meaning you have everything you need to fit it to your compatible Promoto model. RC Model Shop stocks genuine Losi parts to keep your collection performing at its peak, and we're proud to offer this essential upgrade to UK RC enthusiasts.
Key Features
- High Bite Design — The specially engineered high bite surface pattern provides enhanced friction and superior braking performance compared to standard rotors, allowing you to brake harder and more confidently without losing control of your RC motorcycle.
- Aluminium Construction — Manufactured from lightweight aluminium, this rotor combines durability with minimal weight, ensuring your Promoto maintains optimal handling and acceleration characteristics whilst benefiting from improved stopping power.
- Complete with Screws — The rotor comes supplied with all necessary mounting screws included in the package, so you have everything required for straightforward installation onto your compatible Losi Promoto model without needing to source additional hardware.
- Genuine Losi OEM Part — This is an authentic Losi original equipment manufacturer part, guaranteeing compatibility, quality and performance that matches the exacting standards of the motorcycle it was designed for.
- Direct Replacement — Designed as a drop-in replacement for the front brake rotor on Promoto-MX and Promoto-SM models, making it an ideal upgrade when you need improved braking performance or want to replace a worn original component.
Technical Performance
The Losi High Bite Aluminum Front Brake Rotor represents thoughtful engineering applied to a critical safety and performance component. The high bite surface pattern is not merely cosmetic—it's a functional enhancement that increases the contact area between brake pad and rotor, resulting in more consistent friction and superior stopping force. This is particularly important in 1/4 scale supermoto racing, where the motorcycle-style riding position and road-racing dynamics demand precise brake modulation at high speeds. The aluminium material choice is deliberate: whilst steel would be heavier and potentially overkill for RC-scale applications, aluminium provides the ideal balance of strength, thermal properties and light weight that keeps your Promoto's weight distribution optimal. The inclusion of mounting screws means installation is straightforward for anyone with basic RC model experience, and the part slots directly into the brake system of both the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR and compatible models. Whether you're upgrading from a standard rotor or replacing a worn component, this genuine Losi part ensures your motorcycle RC model maintains the braking performance standards that competitive and recreational riders expect.
