Axle D50 x 1030 mm, Type E

OTK Rear Axle – Type E (Extra Soft)
The softest rear axle in the OTK range, designed for maximum flex and grip under low-traction conditions such as rain or cold tires. Type E provides greater chassis flexibility and improved rear tire contact with the track surface, resulting in increased traction and smoother power delivery. Perfect for wet setups or low-grip circuits.

Compatibility: Fits all OTK chassis with Ø50 mm rear axle (Tony Kart, Kosmic, Exprit, Redspeed, Gillard, EOS and others).
Application / Position: Installed as the main rear axle in 50 mm bearing supports and hubs. Typically used when higher rear grip and a more forgiving chassis balance are desired.
Material: Manufactured from OTK’s proprietary axle steel, combining strength, elasticity, and controlled flex for optimal performance.
Installation / Use: Mounts directly with standard bearings and hubs. Recommended to check alignment and clean after wet or damp sessions.
Specifications & features: Extra-soft axle with maximum torsional flex. Optimized for wet and low-grip conditions.
Delivers enhanced traction and stability. Can be paired with axle stiffeners for fine-tuning rigidity.
