In 1966 Honda, after winning 5 championship titles in the World Grand Prix road racing series, decided to withdraw from the GP circuit. They wanted to head back to laboratory and work on a new weapon. Their new target, high performance consumer machines. Honda planned to turn every motorcycle rider into a GP motorcycle racer and they would do it with technology learned on the race track. For the next 2 years Honda worked on many ideas, and different bikes but, it wasn’t until February 1968 that Honda officially started to design and build the bike that would forever change motorcycles.
In 1968 production motorcycles didn’t come with disc brakes or a large displacement inline 4 cylinder engine with a overhead camshaft. These features only came on exotic gp race motorcycles. That changed in January 1969, Honda dropped the cb750 K0 and the motorcycle world was forever changed. If you had the small sum of $1495 you could buy a sport bike with disc brakes and a SOHC engine. Honda had effectively changed the game with the K0. Now anyone could go down to their local dealer and buy a state of the art motorcycle. This gave Honda a huge advantage over the competition. Triumph, Harley Davidson and in particular its British rivals all headed back to their design boards with some of them never to return to the market.
In 1969 Honda dropped an atomic bomb on the motorcycle industry. They made a machine that still to this day effects design, handling and styling. The 1969 and 1970 Cb750 K0 are some if not the most collectible motorcycles ever mass produced with some going for as high as $25000
