Hi the 400 zed looks a little rough for the starting price !. Still not an easy bike to find. The 73 has the best motor - bolt flange exhaust gives more umph than a 74-75lip flange . The cornering is great- but straight line stability is not as good as a red frame 74...the rear kicks and hops a bit when you really get going ove the rough . This bike still has mudcatchers which I would replace for racing . The pics are to dark to see what its really like ? The mullholland rear shocks wer never much chop either .
With some work this will be a very competitive bike wheels, GMC pipe , new tyres , shocks ...ignition and the list may grow when its taken to bits ...... Drakey just sold one to GB for much less and it was race ready ...with history ...I have a 75 falta 400that will be ready for sale later this year .
It will be perfect for around 5k nos gen alloy tank rebuilt engine , replated and painted, GMC pipe etc to give you some idea ...
