Tamiya chassis explained: TT-01, TT-02, TA, TB, XV and MF
A practical guide to identifying and choosing Tamiya chassis families.
With Tamiya, the chassis name gives an initial indication of a radio-controlled car's layout, intended use and upgrade potential. TT-01, TT-02, TA, TB, XV and MF are different chassis families with different architectures and tuning options.
TT-01 and TT-02: beginner-friendly Tamiya chassis
TT-01 and TT-02 are four-wheel-drive shaft-driven chassis designed for simple handling and accessible maintenance. The newer TT-02 is widely used and offers a modular design with many optional parts. It suits touring, rally-style and leisure bodies.
TA and TB: more tuning potential
TA and TB families are better suited to drivers who want more adjustment. Suspension, anti-roll bars, differentials, dampers and gearing become increasingly important for sportier track driving.
XV and MF: specialised layouts
XV chassis are associated with more specialised four-wheel-drive models, while MF chassis are designed for front-wheel drive cars. Their mechanical layout and cornering behaviour differ from TT and TA platforms.
How to identify a Tamiya chassis
- Check the kit or chassis reference.
- Identify the drivetrain: 4WD, rear-wheel drive or front-wheel drive.
- Compare wheelbase and width with the body.
- Check available spare and upgrade parts.
- Match the chassis to touring, rally, drift or track use.

FAQ - Tamiya chassis
Is TT-02 better than TT-01?
