Motorbike enthusiasts will be polishing their chrome as the Mount Gambier Classic and Vintage Motorcycle Show drives spectators to the City Hall this weekend to raise money for Cancer Council SA.

Mount Gambier Classic and Vintage Motorcycle Show organiser Tyrone Mustey came up with the idea for the fundraiser in 2014 while staying in a medical ward in Flinders Hospital.

Mr Mustey experienced a “wake up call” when he met a young boy who had lost his arm and leg to cancer.

Mr Mustey said he decided if he was going to host such an event, he wanted to do it for a worthy cause.

The past seven shows have raised more than $20,000 for Cancer Council SA.

The event usually draws up to 1000 spectators to view nearly 50 pre-1990 motorcycles from dirt bikes to race bikes, immaculate restorations and barn finds.

This year’s show will take place on Saturday from 9am-6pm and Sunday from 9am-2pm.

Mr Mustey said he was constantly surprised with the new bikes that roll in each year.

“There are some very rare motorcycles in this region, some of which there might be another two or three in the world,” he said.

“We had one a few years ago that had spent 35 years built into a wall in a shed and had not seen the light of day.

“I have a guy that’s popping down from Adelaide and I never know what he’s going to bring but …. last time he popped down a couple of years ago he bought a 1990 Harley, all original that he still rides.

“I have run car shows previously but I wanted it to be more laid back and informal and cater for older bikes and older members of the community.”
