Five of the six class titles will be up for grabs when the 2015 G H Motorcycles/Husqvarna/Eastern Centre Solo Enduro Championship reaches its climax on Sunday at the fifth and final round at Butley in Suffolk.

Only two riders can win the Championship class and it will be between Woodbridge’s Aston Bird and reigning champions Jamie Roper of Sudbury Motor Cycle Club.

Roper will need at least a third-place finish to overhaul his rival and with several British Championship riders expected to compete, iy may be a big ask for the Sudbury man.

Braintree’s Will Hughes has already won the Expert class so five riders will battle it out for second and third.

Competition sponsor Gavin Hockey, of Sudbury, leads the Expert Veteran class on 71 points, with Phil Roper (Sudbury) second on 58 and current class champion Mark Chapman on 53.

Martin Stevens (Diss), who led the Clubman class for the first two rounds now finds himself joint second with Ryan McDonnell (Sudbury) on 58 points, with both behind Alex Rampton (Sudbury) on 65 points.
