TAS Racing stepped up to the British Superbike Championship in 2008 after four successful seasons in the British Supersport Championship. The Relentless-liveried Suzuki squad moved to BSB as the reigning British Supersport champions with Michael Laverty. In 2008 Laverty proved that the Relentless Suzuki by TAS squad could mix it at the front with the already established teams in the paddock and in their second season they are looking to build on their experiences from their debut year and look for a maiden podium finish and more in 2009.

The team were also on the British Supersport Championship grid in 2008 with Ian Lowry for a third consecutive season and he ended the year third in the standings after a tally of five podium finishes including two race wins. Lowry has progressed with the team to BSB for the new season and will be joined by Atsushi Watanabe who returned for a second season in BSB.

In 2009 Lowry had some impressive performances in his BSB rookie season, with a best finish of fourth at Cadwell Park and the final round at Oulton Park. Watanabe though failed to deliver the results and languished down the final championship standings. The team lifted the Metzeler National Superstock 1000 Championship crown with Alastair Seeley dominating the title chase with an impressive nine race wins. The team then promoted him to BSB, with the newly crowned champion debuted the new Evolution specification Relentless Suzuki at Silverstone where he scored a top ten finish. Seeley moves to the Superbike team full-time in 2010 with his team-mate yet to be signed.

The Irish TAS Racing team is managed by Philip Neill and the squad initially started competitive racing on the roads in 2001. Since their inception they have amassed an impressive résumé including lap records and wins at all the major road race events including the Isle of Man TT, North West 200 and the Ulster Grand Prix.
