Kyosho 1/8 Inferno MP11 .21 Nitro Powered Racing Buggy Kit

The off-road legend reborn..First full model change in six years!

The 1/8-scale GP buggy Inferno series stands tall as Kyosho’s flagship R/C car line, not only winning multiple world championship titles but also delivering the pure thrill of driving at the highest level. Now, the legacy continues with the debut of the next-generation MP11—the first full model change since the MP10 launched in January 2019.
While continuous updates have kept the MP10 at the forefront of global competition, the MP11 takes a bold leap forward with all new design. Key changes include a newly developed main chassis, revised suspension and drivetrain systems, and an all-new body—all engineered for elite racing performance.
One of the most significant changes is the revised front/rear weight distribution. With a more front-biased balance compared to the MP10, the MP11 delivers remarkably smooth handling that reduces driver stress. Coupled with optimized suspension geometry, the MP11 also achieves higher cornering speeds.
The range of adjustable settings has been greatly expanded, and maintenance has been significantly improved—critical advantages for adapting to different track sizes and surfaces around the world.
The MP11 also debuts a completely redesigned body and a new rear wing with matching wing stays, offering high-level aerodynamic performance perfectly tuned to the chassis.
Carrying the Inferno legacy into a new era, the MP11 doesn’t just aim to win—it’s built to elevate every aspect of the racing experience, from setup to performance to the pure thrill of commanding one of the finest machines on the grid.

Key Features:

• The Inferno series carries forward its winning legacy at World Championships and major races with a complete model regeneration.
• Features the Inferno’s proven shaft-driven 4WD system.
• All new 3mm 7075 aluminum main chassis is hard anodized (True hard anodizing) design. Engine is now moved forward 1mm and 1mm to the centre.
• Repositioned R/C electronics and battery mounting points shift the center of gravity forward for more responsive and intuitive control.
• New body and rear wing designs optimized for improved aerodynamic performance.
• Reinforced bevel gears inside the differential boost durability.
• Spur gear and clutch bell use 0.8 module enable easy fine-tuning of gear ratios.
• Updated suspension geometry delivers superior surface tracing performance.
• Front and rear oil shocks use a diaphragm design as standard for smooth, stable shock function.
• Front and rear shock stays are made of high-rigidity 7075 duralumin. Rear shock stay is lightweight design. The front is 5mm thick, and the rear is 4mm thick. Also, the stay mounting screws have been changed from 4mm to 3mm.
• New servo saver design minimizes impact of dirt particles by repositioning the spring.
• Steering crank servo rod mount changed to a bushing type for adjustable steering response.
• Resin front upper deck effectively absorbs shocks from surface for improved chassis stability.
• Stopper has been added to the pressure tube connecting the fuel tank and muffler to prevent snagging during running.
• Unassembled kit includes body and wing

The MP11 chassis emerges from a bold reimagining, with a completely new design from the ground up, blending cutting-edge innovation with original design DNA to establish a new platform for the next generation of the Inferno series.

The all-new body is engineered for peak aerodynamic efficiency, with a finely tuned front-to-rear downforce balance that enhances stability, sharpens control, and pushes cornering speed to the limit.

New front and rear lower suspension arms support optional carbon plates for adjustable rigidity, adapting easily to varying surface grip levels. Updated droop screws reduce chassis friction for improved chassis wear.

High-rigidity aluminum lower suspension shaft holders are used to withstand the intense loads of off-road driving. The suspension shafts are mounted via precision resin bushings, which can be interchanged to fine-tune toe angle and roll center geometry.

The aluminum front hub carriers feature a 12° kingpin angle which is increased from the previous MP10 TKI3 model and 18° caster angle. This enhancement improves high-speed stability and boosts overall drivability.

The red anodized plate of the lightweight aluminum knuckle arm, designed for a 12° kingpin angle, is a separate part.

Compared to the MP10, the rear hub mounting position is set further outwards. This reduces the camber change rate, resulting in greater stability on high-grip surfaces and during high-speed driving.

By covering the joint part of the universal swing shaft with an aluminum cap, it has the effect of preventing splashing of grease and improved durability, as well as protecting a damage from dust. It also protects the pins from falling off in case of damaging the joint parts.

The center differential holder features a new split upper-lower design, simplifying maintenance by enabling differential removal without disturbing the brake cam. Return springs have also been added to the brake pad bolts for improved reliability.

Front and rear bulkheads feature a new design that separates the bearing holders from the bulkheads, enabling adjustable differential mounting height for precise grip tuning. Larger differential pinion bearings are also employed to improve durability under high loads.

The front and rear bulkheads feature a split design, allowing for easier access to the differential and improved maintenance. A mechanism has been incorporated to attach the sway centering collar, resulting in an unhindered stabilizing effect.

Battery for the R/C system has been repositioned further forward to adjust front-to-rear weight distribution. This forward-biased center of gravity improves handling on rough terrain for more predictable, user-friendly control. Two mounting positions are available for the hump receiver battery pack.

Optimal fuel supply to the carburetor and heat countermeasures through effective heat dissipation fins. Additionally, a stopper has been added to the pressure tube connecting the fuel tank and muffler to prevent entanglement while driving.

Equipped with a resin stiffener to reinforce rear chassis rigidity. By swapping the separate insert plates, rear pitch and roll stiffness can be adjusted. The bushings at the bulkhead base are replaceable. The standard plastic bushings are suitable for relatively high-grip surfaces and conditions with fewer bumps. Additionally, by switching to rubber bushings, use on bumpytracks or low-grip surfaces becomes possible.

The rear wing stays are lighter than previous versions, and by swapping spacers placed between the wing and the stays, you can adjust the rear wing's position both front-to-back and vertically. The newly designed rear wing also features drilling guides on the flap to allow for customizable aerodynamic tuning.

The new wing is lightweight and rigid, providing greater downforce. It features 16 pre-marked airflow holes that can be opened to fine-tune downforce for any track or condition.
