INFERNO MP9 TKI4 V2 Race-Bred Nitro Buggy from Kyosho

Kyosho 33021 INFERNO MP9 TKI4 V2 brings competition-derived features into a ready-to-run 1/8 scale package. Its design focuses on controllable handling and adjustability for different track surfaces, making it a solid choice for club racers and weekend tuners.

Suspension Geometry and Track Behaviour

The TKI4 V2 platform retains long front arms and a 17.5 degree caster front hub carrier to improve stability through high speed turns and to provide predictable steering response. The forward cabin profile also helps maintain grip when cornering hard.

Engine Characteristics and Usability

Fitted with the KE21SP engine, the buggy offers a smooth torque curve and reliable starts thanks to the recoil starter and rear exhaust layout. The supplied break-in ring helps you perform a controlled initial run-in for longer engine life.

Servos, Shocks and Fine Tuning

High-torque KS5031-09MW waterproof servos manage steering and throttle input with consistent response. Precision machined big bore oil shocks deliver effective damping across rough sections. Adjustable wheelbase, camber, toe and caster allow setup changes to suit soil, grass or hardpack circuits.

From shock tuning to sway bar adjustments, the MP9 TKI4 V2 gives plenty of scope for small setup changes that make a big difference on lap times.

For those who prefer hands-on setup and tuning, the INFERNO MP9 TKI4 V2 is a capable platform that balances performance and practical features for trackside adjustments.

Bring spare clutch shoes, diff oil, a set of tyres, and a couple of servo horns. Those parts cover most common on-track repairs and setup swaps.
Yes, with the right tyre choice and softer shock settings, the buggy adapts to grass circuits, though fine tuning of ride height and diff track can improve handling.
The KE21SP is straightforward to service with standard tools. Regular air filter care, glow plug checks and proper fuel will keep it running well.
Try softer shock oil and increased rear toe-in to improve traction on loose surfaces. Small tyre adjustments often yield the best improvements.
