British Supersport contender Stuart Easton is confident he has the package to challenge for the title on his return to the series this season.

The Scottish rider, a former British Supersport champion, was in upbeat mood following his first test at Cartagena in Spain last week with Northern Ireland's Mar-Train Yamaha team.

Easton, who will also return to the North West 200 in May following a horror crash there in 2011 that left him with life-threatening injuries, expects to be winning races again sooner rather than later.

"I'm fairly happy how it's gone and we've made good progress every day," said Easton.

"I've learnt more with the bike every time we've ridden it, so if we can keep improving then move on to the tests in England we are on the right track.

"This test has given me the chance to get comfortable on the Mar-Train Racing R6 and I'm not a million miles off the pace - even though the pace has got quicker every day - so that's got to be a positive.

"I'm content and I've got confidence that the package is there to do the job."

Easton has quickly gelled with his new team and doesn't anticipate any issues adapting to the Supersport race environment after a long spell riding Superbike machinery.

"I'm also really comfortable with my new team and my new crew so it's all looking good.

"After this week I think I'll have no problem adapting back to the Supersport class," he said.

"Winning races is never easy but I'm confident for sure and looking forward to the start of the season now."

Last year, Dublin rider Jack Kennedy agonisingly missed out on the title for the Mar-Train team at the final round of the series.

Kennedy had the championship at his mercy after main rival Glen Richards crashed out, but the Irishman himself suffered heartbreak when his Yamaha developed trouble and he was forced to retire, handing the crown back to Richards.
