head with RAM(for ram air system) think it's a twin 380 the 3 cylinder was 550 GT 380 380 et 550 furent toutes deux des "trois pattes". Pas la GT 250 bicylindre, produite un temps avec le refroidisseur "Ram-Air System"... Et au vu des échappements, c'est un twin, pas un triple...
THis is certainly a GT250 ( a twin) very popular bike in UK at this time, as 250s could be ridden by learners on L plates . GT380/550/750 all had three cylinders
