Birel 1/5-scale Racing Kart
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.
