The 2023 BIRELART RY30 S15 Chassis – British Champions 2019/2020 LGM Junior Champions 2021



John Mills Engineering is the proud, sole UK importer of the legendary Birelart chassis made in Italy, the full range of 2023 models are available from stock along with the all new Charles Leclerc chassis and Kubica line of chassis. We require trade dealers in select areas.


In 2019 the package won 6 from the 8 rounds of the British MUK series, it even finished 2nd in the other 2 rounds. In 2020, driver Danny Keirle (ex World Champion) and the Jade Racing Team proved once again to be the class of the field winning another 6 rounds, so big was the lead he didn’t even have to take part in the final round and now X30 driver Oliver Stewart is 2021 LGM Junior Champion. This is some chassis and one that performs at every race track in the UK, drivers are finding the advantages of the Birelart / CL / Kubica chassis, being easy use and set up straight from the box. Birelart / CL / Kubica has a range of karts to suit most classes, from the top end OK, right the way down to the Bambino Kart which is the smallest in the range, all of which are available from stock. All karts use Freeline components, which are some of the best around and widely used by other manufactures. If you would like a test or interested purchasing a chassis please call one of the team on 01636 626424
