JL EXHAUSTS: Racing in the DNA
Jim "JL" Lomas started exhaust manufacturing in Wymondam, Norfolk, UK in 1979. The first products were built for racing, e.g. for the Yamaha TZ250 and TZ350. In the early 80's many top British racing teams used JL products, including Padgetts, Zip Karts and Steve Webster.
1988 had been the first season to supply exhaust systems for Superkart racing. In that first season JL finished first and second in the British 250cc Superkart Championship. From 1989 to 1992, JL's exhausts won every major Superkart 250 championship around the world, including the UK, Sweden, South Africa, Australia, Europe and the World Championship.
Jim Lomas himself was also active on the track: his first vehicle was a Honda CB 720, with which he successfully participated in various competitions. The highlight of his active racing career was without doubt winning the British Grand Prix in 1969!
At present, JL EXHAUSTS produces exhaust systems for 2-stroke motorbikes, classic Vespa, Lambretta and motocross vehicles, which convince not only through technical innovations but also through their high-quality workmanship. In 1993, the company headquarters in Great Britain were moved to the Czech Republic.cms_ There, the exhaust systems are still handmade under the critical eye of the master craftsman. In 2015, Jim's son Oliver took over the company, continuing the family legacy and driving the future of two-stroke machines.
