"I have just been reading Peter Drakeford’s story about Keith Stacker, in the latest Nov/Dec issue of Old Bike Australasia.
It’s an enlightening read about someone who was certainly passionate about his motorcycling, especially Scrambles and then Motocross. Starting off with a 1938 BSA and going right through to the 2 stroke period, he modified and re-engineered many of his bikes on his way to winning many championship races.
As well as his favoured early BSA’s he rode many brands such as Greeves, Jawa, CZ, Husqvarna, Ossa, Yamaha, and the bike we were more later accustomed to associate with his name - Maico.
It’s worth reading, with good photos too."
