Serpent SER400043 Medius X20FWD '21 Carbon 1/10 Competition Kit  [SER400043]

X20FWD '21 by Serpent SER400043: Tunable Carbon Touring Chassis

The Serpent X20FWD '21 takes the X20 foundation and adds targeted improvements for adjustability and balance. The mid-motor configuration and one-piece motor mount keep drivetrain alignment stable while leaving room for setup changes.

Refined geometry for sharper steering

The suspension benefits from multi-season development and uses the pivot ball layout for straightforward setup changes. A revised 2-point steering crank helps you adjust Ackermann values for cleaner cornering lines.

Track side flex tuning and material choices

Suspension arm geometry now allows deliberate flex tuning to match grip levels. Optional carbon pieces let you stiffen the chassis incrementally, while the LCG anti-roll bar links to the upper arm to manage weight transfer.

Flexible drivetrain and battery placement

Designed around stock racing needs, the drivetrain ships with a 38/21 ratio and supports a practical range of gear choices. Several battery layout options enable quick shifts to achieve desired handling balance.

Durable parts with race feel

Components are selected for silent, efficient operation, including dual ball bearing DJC shafts and CVDs that minimise friction. The adjustable steering hub gives scope for axle height and roll centre setup to suit driving style.

The X20FWD '21 suits drivers who want a race ready, tweakable platform that responds predictably to setup changes and delivers consistent lap times.
