Tamiya 95143 Dual Ridge Jr. VZ - Japan Cup 2021 Mini 4WD Polycarbonate Collector Kit  [95143]

Dual Ridge Jr. (VZ) Japan Cup 2021 - Product Summary

The Tamiya 95143 Dual Ridge Jr. commemorates the Japan Cup 2021 as a limited-run Mini 4WD kit. It marries a light polycarbonate body to the compact VZ chassis to create a nimble platform for track use and customisation.

Shell Design and Visual Options

The aerodynamic polycarbonate shell keeps weight down and helps high speed runs. Because the body is clear, builders can apply their own paint schemes and use the included clear stickers to finish a personalised look without adding weight.

Built-in Traits of the VZ Chassis

The VZ chassis focuses on compact, lightweight construction with reinforced sections like the bumper and rear stay mount for improved durability. It is well suited to upgrade parts, allowing racers to refine handling or robustness.

• Low-friction 620 plastic bearings made from POM cut drive resistance.
• Chassis frame and A parts are formed in ABS for strength.
• Standard gear setup of 3.5:1 offers a practical compromise of torque and speed.

Personalisation and Performance Tuning

Performance can be tailored by changing motors, testing different tyres, or re-gearing to better match a circuit. The kit works with a broad range of Tamiya accessories and common Mini 4WD upgrades.

Build Advice and Powering the Model

Assembly is aimed at hobbyists at any skill level, with clear instructions and manageable parts. The kit contains a Type 130 motor but requires two AA batteries to operate, matched to the 3.5:1 gear ratio.

The Tamiya 95143 Dual Ridge Jr. (VZ) Japan Cup 2021 edition is a practical choice for racers who want a light, tuneable Mini 4WD with strong aftermarket potential. It balances an easy build with meaningful upgrade paths for track optimisation.
