Stuart Easton has won his second MCE British Superbike Championship race of the season after coming out top in a thrilling four-way fight for victory at Oulton Park.

The Scot was embroiled in a race-long exchange with Leon Camier, James Ellison and Tommy Hill from start-to-finish, but it would take a dramatic last lap move over new champion Camier to put the win beyond his rivals.

Arguably the most exciting race of the season thus far, it nonetheless began on a somewhat sour note after the first start was red flagged three laps in due to a vicious accident for Karl Harris.

A frantic start had seen Easton and Hill dispute the race lead in the early stages, the pair already swapping positions once when Hill attempted to regain the lead on the long left-hander at Island.

However, with both Hill and Easton running wide, the following Harris attempted to capitalise by moving up the inside, a line that would become the outside heading into the Shell hairpin. Unsighted to the left of the recovering Hill, Harris was baulked onto the grass and left with no choice but to go off. With his SMT Honda digging into ground, both bike and rider were flung across the gravel, Harris himself hitting the wall hard.

The race was duly stopped while medics attended to Harris, who remained conscious but is reported to be suffering from a suspected back injury.

With the race restarted in the order they completed the third lap, Hill began on pole position, but while it was fourth place Ellison that got the best getaway, Easton would assume the position again heading into Cascades.

Undeterred, Ellison struck back on the run down to Hizzy's, slipping up the inside of Easton to move back ahead, the pair followed by Hill, the fast-starting Simon Andrews and Camier.

With the top five quickly pulling away from the chasing pack, led by Chris Walker and Sylvain Guintoli, Andrews was the man on the move, getting the better of Hill to move into third place. Camier followed him through with a bold outside-to-inside pass through Island and Shell, a technique he would repeat on lap four to pass Andrews for third.
