CB history

The first CB450 was introduced back in 1965, it was called the “Black Bomber” due to the fact they came in just one color, black, and the fact the CB450 was then the biggest bike Honda produced. It shook the motorcycle world with his over head camshafts, electric starter, torsion valve springs and an astonishing 43 Hp.

The first CB motorcycles came with the type CB450 K0. Later followed by the K1 in 1968 up to K7 which build year was 1974, this was the last year these lovely bikes were build. From the K1 up to the K7 the bikes came with 5 speed gear boxes.

Racing History

The potention of the CB450 was noticed by professional motorcycle racers and club racers. The CB450 was banned from club racing in England, they said a real bike should not have over head cams, wonder why. Nevertheless, it was just a matter of time until the CB450 was on the racing track.

In 1969 Graham Penny won the production 500 cc class on the Island of Man on a CB450. That same year Australian Terry Dennehy made name to beat Giacomo Agostini in the Finnish Grand Prix. In that same season Terry was leading the East German GP ahead of Agostini until the bike suffered a lack of fuel and Terry had to give up. Dennehy came from Australia to Europe to compete in the GP series, he traveled light from the other side of the world and planned to purchase a competitive bike in Europe, he only found worned out racing bikes and then decided to try the CB450. Terry was based in Italy where he met Othmar “Marly” Drixl, a Swiss frame builder. Drixl made the now famous Drixton frame in conjunction with Englishman Syd Lawton. That’s where the name Drixton is coming from, the combination Drix – ton.
