that bike is real, is Brett's bike, in Sydney, 81 Jota engine, is one of the Serbs we imported when we did the mass 19 Laverda import all from Serbia into QLD
Brett did that paint job himself, pretty cool, he rode that bike to our last race meeting at Morgan Park
Is a very late Series 2 engine, #812*, one of the last 10 x Series 2 engines ever built
