Just viewed the catalogue, most Vincents I have seen in one sale for a long while although this may drive the prices down a wee bit.
Regarding the Honda Dream,although a nicely engineered machine they allways strike me as being far off a CR110 Replica as the engine/gearbox construction differs somewhat.Although they gave the max revs of the Cr110 as 13500 they needed to be reved much higher than this if you wanted to win anything and it was not uncommon to see the needle stuck on 16000rpm without any adverse effect on the engine.It was one of the most reliable bikes I ever raced although I modified the drive side bearing on mine as the original caused crankshaft failure.
