The Car

The Leastone 1000 is an Irish-built single-seater designed to deliver an affordable “slicks and wings” experience for both aspiring drivers and seasoned racers. Equipped with a Suzuki GSXR 1000 engine, it features a 6-speed sequential gearbox and fully adjustable multi-element wings. It has been a consistent frontrunner in bike engine classes of both Formula BOSS Ireland and Monoposto (BOSS3 and MonoMoto 1000), securing class titles in both categories in recent years.

Formula BOSS Ireland (Big Open Single Seaters) is Ireland’s premier single-seater racing series, featuring high-powered cars such as Formula 3, Formula Renault, and bespoke machines like the Leastone 1000.

The championship fosters a friendly, club-level atmosphere while delivering serious racing at iconic UK circuits like Silverstone, Brands Hatch and Donington Park.
