Kyosho have released the Birel R31-SE, a third generation kart that sets a new standard for scale appearance and performance. This 1/5th scale chassis 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. Featuring 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 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.
