Car, 1/24 JK C21 Mazda Dyson M25 48P 1/8" Axle - O1B113DS11

1/24 Scale • Cheetah 21 Steel Chassis • M25 Motor • 48-Pitch Gearing • 1/8" Rear Axle • Ready to Race

Think of this as the big brother to our popular 1/32 JK Cheetah cars. Built around JK Products' full-size 4-inch Cheetah 21 chassis, this 1/24-scale analog racer delivers the same basic formula—light weight, mechanical grip, a flexible steel chassis, and serious performance—in a larger and more substantial package.

The car comes factory assembled with an M25 motor, 48-pitch drivetrain, 1/8" rear axle, foam rear tires, and a lightweight Mazda Dyson LMP-style racing body. It is intended for true analog racing rather than magnet-dependent home-set performance.

🏁 Cheetah 21 Performance

The JK C21 is a multi-piece steel flexi chassis designed to let the chassis and body work together through the corners. Rather than relying on strong magnets to hold the car to the track, grip comes primarily from chassis setup, wide foam rear tires, and driver control.

For racers familiar with our 1/32 Cheetah cars, the concept will feel familiar—but the 1/24 car gives you a larger chassis, 1/8" running gear, and the substantial feel of a traditional commercial-style racing car.

🎨 Screen-Printed Racing Body

This version includes JK's screen-printed Mazda Dyson body. The photographs show the body and livery supplied with this specific car, so please use the product photos as your guide for the exact appearance.

The 0.020" body is heavier and more durable than ultra-thin competition bodies, making it well suited to regular club racing, home layouts, and applications where durability matters as much as shaving the last fraction of a gram.

🔌 Track Compatibility

This is a true analog racing car intended for tracks with adequate slot depth, power, and clearance for commercial-style 1/24 equipment.

• Excellent for routed wood tracks
• Suitable for Carrera Evolution and Exclusiv track when operated as a true analog layout
• Ideal for Carrera layouts equipped with an OmniSlotBox analog/digital switching system
• Not intended for standard Carrera Digital operation without appropriate conversion

Commercial-style guides and larger 1/24 running gear may require more clearance than conventional home-set cars, so always confirm track and guide clearance before use.

⚡ Power

The M25 is a performance-oriented analog motor. For best results, use a regulated power supply capable of supplying adequate current to each lane. A properly powered track will provide more consistent acceleration, braking, and lap-to-lap performance than a lightly rated home-set supply.

🛞 Foam Tire Performance & Care

Foam rear tires provide strong mechanical grip without depending on magnetic downforce. They perform best on a clean, properly prepared racing surface and are not recommended for very dry or dusty tracks.

Foam tires should be protected from drying out when the car is stored. A simple solution is to keep the entire car in a sealed plastic bag or container between race sessions.

A very light application of an appropriate foam-tire conditioner can also help preserve softness and improve grip. Apply tire treatments sparingly and remove excess before placing the car on the track.

🏎️ From Jim

If you enjoy our 1/32 JK Cheetah cars and want to experience the same style of lightweight, non-magnet analog racing in 1/24 scale, this is the logical next step. The C21 chassis gives the car the feel of a traditional commercial race car while remaining straightforward to maintain, tune, and repair.

It is fast enough to be genuinely entertaining, durable enough to race regularly, and built from replaceable racing components rather than being a disposable home-set car.
