Kyosho was the first to bring racing karts to the RC market back in the 70's. There was also a second-generation kart from the early 90's. The Birel R31-SE is a third generation kart that sets a new standard for scale appearance and performance. The Kyosho Birel 1/5 Racing Kart is a scale replica of the popular R31-SE kart used in international FIA competition, where many Formula 1 drivers got their start in racing.

The Kyosho Racing Kart features scale bodywork and graphics identical to that of the full-size racing kart. Its factory assembled, so with some minor prep work, the R31 is ready to go in a very short time! The extreme performance and thrill of karting can now be experienced again with this latest generation replica of the famous Birel kart.

The R31 features a unique drivetrain identical to that of the full-size kart with a 2wd solid axle. This drive system along with the rigid suspension is what gives these high-performance karts such blistering performance, often rivaling that of many full-blown racecars. This is not just a fun model for beginners - it does feature an easy-to-start GZ15 engine and some basic chassis adjustments, but like the full-size kart, its performance is explosive, so it can capture the imagination of a wide range of enthusiasts from beginners to experts.


  • Awesome Detail - Fully replicated 1/5th scale model of the Birel R31-SE. Paint scheme replicates the actual Birel graphics and color.
  • Realistic Chassis - The Kyosho R31 is a perfect hybrid between the full-size kart and RC with trailing steering knuckles, belt drive system, and T-bar rear suspension.
  • Low CG - The chassis features a super low center of gravity and it's tuned for direct, responsive steering feel just like the full-size kart.
  • Powerful Acceleration - Newly developed exhaust pipe allows smooth but powerful acceleration and top speed.

  • High-Grip Rubber - Equipped with true-to-scale scale rubber tires featuring high-grip rubber, so the kart not only looks great, it also has great traction and superior handling.
  • 75CC Fuel Tank - Flip-top 75cc fuel tank allows for quick refills while the engine is running, so you can keep running for as long as you like.
