Eurogang EP: 4
A parallel twin that looks more Japanese than British (from what I can see anyway), the pipes don't look right for XS 650, this leaves XS500, Z750B or a few Honda 250/350/450's. Any other shots? No other shots. But then there's this Gus Kuhn Commando? Signal Orange was a 1971 colour, Tangerine was an option in '74. Commando production racers (and replicas) were nearly always Yellow. Laverda SFC? I'd forgotten about those (never seen a real one), I'd considered Montjuic but they were 78-79 onwards, I think you've nailed it, they're all orange .

Beautiful, a mate had a proper Slater Bros' Jota, the rumble & roar from that could pop the bulbs on streetlamps as it went past
