Former British Supersport title contender Hudson Kennaugh will make his Isle of Man TT debut in 2010.
The South African, still seeking a full time British Championship ride for 2010, finished runner-up in the 2008 British Supersport Championship and fifth in that year's World Supersport Championship round at Brands Hatch.
Also present on the newcomers' list for TT2010 are Stephen Thompson, a leading contender at both the Macau Grand Prix and North West 200, plus fellow British Superstock regulars Daniel Hegarty, Kenny Gilbertson and James Hurrell.
Meanwhile, David Jones will be one of the youngest riders on the grid, the 21-year having finished in solid fifth place in last year's British Supersport Cup.
An interesting entry was received from Gary May, one of Britain's leading 250cc riders at the end of the '90s and MRO Champion as recently as 2006, whilst Irish Superbike champion Brian McCormack finally gets to make his debut after being forced to miss out twelve months ago.
There's further overseas representation with Australian ace David Johnson, the Adelaide rider having commenced his UK career back in 2002 against Cal Crutchlow, Tom Sykes, Craig Jones and a certain Guy Martin in the Juniorstock Championship, whilst recent years have seen him frequently picking up points in the British Superbike Championship.
Swiss rider Herve Ganther, a former star of the European Superstock Championship, will be bringing his Honda Switzerland machines with him, whilst Clinton Pienaar is one of South Africa's most highly respected, and successful, riders.
