Kyosho INFERNO MP9 TKI4 V2 Readyset for Off-Road Racing

The Kyosho 33021 INFERNO MP9 TKI4 V2 combines competition-level features in a ready-to-run 1/8 scale nitro buggy. It is aimed at enthusiasts who want a robust platform with plenty of setup options for varying off-road conditions.

What the Chassis Brings to the Table

Based on the MP9 TKI4 competition layout, this model includes long front suspension arms and a 17.5 degree caster front hub carrier to enhance stability and predictable steering. The forward cabin shape also contributes to balanced weight distribution through corners.

Engine Setup and Running Ease

The KE21SP engine provides a practical mix of torque and top end for track use, paired with a recoil starter and rear exhaust for easier handling. The supplied break-in ring helps ensure the engine is bedded in correctly for reliability.

Electronics, Damping and Adjustability

KS5031-09MW waterproof servos provide solid steering and throttle response in all conditions. Machined aluminium big bore oil shocks manage impacts effectively, while the adjustable wheelbase, camber, toe and caster let you refine the buggy for hardpack or rutted terrain.

This platform is well suited to incremental upgrades, from shock pistons to diff oil selection, to match specific track demands and driver preference.

The INFERNO MP9 TKI4 V2 is a practical choice for racers who value a strong baseline and the ability to tweak settings for lap time improvement or event-specific setups.

Tyre choice is key. Use softer compound tyres for loose dirt and more aggressive tread for longer corners. Carry spares to swap between sessions.
The Readyset provides a competitive baseline but most racers make small setup changes to shock settings, camber and toe to match their driving style and the track layout.
Perform staged runs at varying RPM, monitor operating temperature, and follow the break-in ring guidance to seat the engine properly for long term performance.
Upgrading shock pistons, experimenting with diff oils and fitting adjustable turnbuckles can produce noticeable handling improvements without major expense.
