Karl Harris and David Johnson will spearhead British Superbike team PR Kawasaki's Isle of Man TT challenge in 2013.
Harris – who made his debut on the Mountain course last year – and Aussie Johnson will compete in the Superbike, Superstock and Senior races at the world famous event in June on ZX-10R machinery.
Johnson is making his third appearance at the TT and excelled on his debut in 2010, earning five bronze replicas from five rides and setting the third fastest lap by a newcomer ever to win the prestigious Newcomers Trophy.
He missed the event in 2011 but returned last season, claiming top 15 results in the Superbike and Superstock races and setting a new personal best lap time of 125.831mph for the 37.73-mile circuit.
Triple British Supersport champion Harris made his TT bow for Robin Croft's SMT Honda outfit in 2012, lapping in excess of 121mph and finishing 21st in the Superbike race.
'Bomber' is contesting the British Superbike Championship this year for the Liverpool-based Kawasaki team with Johnson challenging for honours in the Superstock 1000 class.
John Jameson, PR Kawasaki team principal, said: “We dipped our toe back in the water with the TT last year, but we're taking things to the next level for 2013, with a full-on assault on the event.
“With Dave and Karl as our riders we believe we have two of the most exciting new riders in the event and we're looking towards breaking into the top ten with both riders for the first time.
“We see this as the start of a long relationship with the TT,” he added.
“PR Racing is particularly grateful to John Birch, Lloyd & Jones, for his long-standing support of the team and specifically for the IOM TT, which he has attended for many years and now as a team sponsor. This should add some real zest to the occasion for him.”
Paul Phillips, TT & Motorsport Development Manager added: “PR Racing Kawasaki are a very well established team in the British Superbike paddock and it is great to have them fully supporting the TT in 2013.
“Their rider line-up is one of the most exciting in the paddock and both riders have the natural ability to go on to challenge for honours at the TT for many years to come.”
