Never one to give an inch on the track, McMahon has offered his spare bike to rival Chris McCausland to keep their fight for the 701cc-900cc historical  championship alive.

They will be part of a program at Symmons Plains next Sunday that includes historical motorcycles from 250cc to 1300cc (built before 1990) plus  250cc, 500cc, 600cc and unlimited modern machines.

Things could not be closer between McMahon and McCausland, who top their class with 165 points each going into Sunday’s penultimate round.

McCausland crashed heavily at the club’s September meeting and, while he escaped relatively unscathed, his bike was badly damaged and will not be ready this month.

Enter McMahon.

‘‘There was no way I wanted to win by default and this will keep things interesting,’’ he said.

‘‘Both my bikes are pretty even, the older one gets out of the corners better, but the newer one has a bit more top end.

‘‘Mind you, after the refinement of his racing CB750 replica, Chris is going to be in for a bit of a shock when he rides my old girl. Besides, we’re not exactly racing for sheep stations.’’

McCausland said it was heartwarming to know someone would offer their spare bike with the championship on the line.

Racing starts at 9am, a canteen will operate all day and the final round of the championship will be held at Symmons Plains on Sunday, November 23.
