It's a little funny the history of my father & motorcycles :-) Dad use to roadrace in England, he had a few beezers was also an RAC officer (would attend automobile breakdowns) with motorcycle & sidecar.
He gave up bikes & moved to Australia to raise a family in the early 60's; I knew nothing about his motorcycling background. One day, when I was 12, I had been hanging-out at the local boat launching ramps and a kid was riding around on a Tas minibike, he offerred me a ride; I was hooked!
I rushed home and said to Mum & Dad "I just rode this motorbike, it was fantastic, can I get one?!!". Mum looked at Dad and said "oh no!" She wasn't saying "no I can't have one", she was saying " oh no he has your (Dads) disease"
Dad said you are not having some stupid lawn-mower powered thing and bought me a new Italjet 50 (from George Bailey Honda in Frankston) that was a correctly scaled-down motocrosser.
Dad had a fibreglass canoe factory next to Alan Lambert Motorcycles (that became Lambert Leathers), Alan's son Roger was racing a Suz TM125 in '73 an Alan took me to my first scramble at Bairnsdale to watch Roger race. From there onwards I always wanted a TM125.
In '74 Dad tipped-in a dollar for every one I saved and we bought a new '74 TM125 and he bought a '74 TS125 for himself; he never rode it, it got stolen & recovered and I fitted TM bits to it to take out the club trailbike class, it's the bike in my avatar pic that Dad took.
Dad's had a few health issues (as I guess most old blokes have) of late and he only has a 50cc TGB scooter but he's thinking of getting a 250 roadbike.
I'll ask him for some of his old bike pics.
