Just a pity that they are not entirely the same bike. The complete bike is a 78C the other bits are from a 78C, 79N (or) 80T that i can see. Tank and front wheel are not C although the frame, forks and swingarm are. Be interesting to see what size the rear barrell bolts are to understand if it is a C engine.
Are C model's all that desireable in Australia given that they cant be used in Pre78 as they arn't a follow on? As far as being an EVO bike they have to go up against a N or T model which is a much better machine. Would be a lot of coin to pull it over from the states for not much return i would think.
