Runfarr Front Brake Disc is a front brake disc for electric dirt bikes engineered to restore braking response and thermal stability for Sur-Ron Light Bee S and S/X. Confident braking on trail runs and urban rides reduces rider anxiety and improves control. Is the Runfarr Front Brake Disc the right upgrade for your Sur-Ron?
⚡ At a Glance
- • Braking Performance: Rapid response and strong sensitivity, designed to maintain stable stopping under heat
- • Best for: Owners of Sur-Ron Light Bee S and S/X seeking a replacement or upgrade rotor
- • Not ideal for: Motorcycles with different bolt patterns or non-Sur-Ron models
Stainless steel front rotor tailored for Sur-Ron Light Bee S and S/X. Engineered for better thermal stability and reduced rotor wear.
Confident Stopping – Thanks to stainless steel construction
Austenitic stainless steel composition gives high hardness and shear strength while resisting wear and ageing. The material tolerates impact and preserves rotor geometry under repeated loads.
More predictable lever feel and consistent stopping power during trail and street use. Less likelihood of warping helps maintain alignment and pad contact over time.
Stable braking under heat – With a controlled friction coefficient and quick heat dissipation
Friction surfaces are engineered for a balanced coefficient that reduces sudden changes during temperature swings. Design promotes rapid thermal transfer to help avoid localised overheating.
Brake bite remains reliable on long descents and repeated heavy stops. Reduced chance of fade keeps braking performance consistent across rides.
Simple fitment and durability – With included mounting screws and wear-resistant finishing
Compatible mounting hardware is supplied to match Sur-Ron Light Bee S/X fitment, and surface finishing resists corrosion and abrasion. Construction aims to limit rotor wear from pads and debris.
Faster installation with fewer missing-parts headaches, and longer service intervals thanks to improved wear resistance. Practical for riders who perform routine maintenance themselves.
