At the weekend in Watlington, a WW2 scramble bike. Not motocross, the sort of scramble that got pilots to their Spitfires. The bike was an upright Raleigh with a 32cc petrol-drive two-strike engine driving the front wheel. Thre motor had an Italian sounding name but given the use, it presumably wasn't Italian. The whole thing was road legal, in that it was registered, taxed (presumably zero rated for age) and insured as a motorcycle.
