High Level Belt-Driven TC On-Road Racing R/C Car

The Serpent Medius X25 takes touring car racing to the next level with cutting-edge design, refined geometry, and race-proven innovation — engineered for drivers who demand maximum speed, precision, and reliability.

About the Medius X25

Precision-Engineered Chassis Design

The Serpent Medius X25 features an updated symmetrical chassis with improved flex characteristics for enhanced handling. Available in both 1.2mm steel with PVD coating for maximum durability or 2.25mm carbon for lightweight performance, the chassis is engineered to provide superior wear resistance and control. Combined with a split top deck tuned for a softer feel, the X25 delivers a responsive and predictable driving experience on all track conditions.

Advanced Suspension Geometry Upgrades

Every detail of the suspension has been refined, from reinforced upper arms with adjustable body stop screws to shock pickup adjustments for better geometry. The anti-roll bar linkage is more precise, making tweak adjustments easier, while new upright inserts ensure rim compatibility without special shims. Pivot ball suspension with small balls keeps movement smooth and consistent, while the double eccentric differential height system allows wide tuning flexibility without bulkhead swaps.

High-Performance Shock System

The X25 introduces 13mm big bore linear shocks with machined pistons included as standard, ensuring unmatched smoothness and consistency. This updated shock design enhances traction, durability, and stability while reducing wear over long runs. Drivers can also opt for progressive shocks for further tuning. The split shock tower design is lighter, stronger, and integrates seamlessly with the new upper arm mounts, boosting both reliability and handling precision.

Built for Competitive Edge

From its even-length Kevlar-reinforced belts to the lightweight front spool with hardened outdrives, the X25 is designed for race-ready performance. The Re-Active Rear Steering (RRS) system comes standard, offering sharper cornering ability, while the integrated servo/RX mount and one-piece motor shaft mount simplify maintenance and spur gear changes. With its extremely low center of gravity, optimized flex philosophy, and world-class input from Dominic Greiner, the X25 represents the next evolution in competitive touring car design.
