The fire, which badly damaged the classic bike, was likely caused by a fuel leak after the bike was over-fuelled, the post suggested.
A witness, who did not want to be named, said the flames were visible from a distance.
“All I saw when I was driving up Taradale Rd was a big ball of flames and black smoke around the intersection,” he said.
“I was completely shocked when I saw the flames engulfing the motorbike.”
The witness said the rider had safely stepped off the bike and was on the footpath with others.
“No one was injured from what I could see.”
The witness said the fire produced “a lot of pops and bangs” but did not appear to spread quickly.
