The History

Former sidecar Grand Prix racer Colin Seeley acquired rights to the Matchless G50 and AJS 7R singles in the late 1960s and developed both the engine and a new chassis, producing the Seeley G50 Racer.

 

Initially the engines were supplied by AMC, however AMC quickly announced that they were ceasing production of the powerplants. This presented the fledgling Seeley operation with a serious problem with regard to the supply of powerplants for the promising machines. Colin's decision to purchase the AMC racing department and manufacture his own engines was both bold and farsighted and at a time when the British motorcycle industry was imploding, would add an illustrious chapter to it's history completely at odds with industry generally.

 

With the supply of engines now secured the Seeley concern entered a golden period with their machines selling well. Production was soon concentrated on the G50 powered example, one of which took Dave Croxford to victory in the 1968 British Championship, a feat he repeated the following season. 1968 had also seen John Cooper secure a victory in the North West 200 whilst 1969 saw Seeley G50's taking 3rd,4th and 5th in the Senior TT and John Blanchard repeating John Cooper's success at the North West 200.

 

Seeley then started fitting the more powerful Norton Commando engine to challange the Rob North's which at that time was the tops,  successes  followed  and the Seeley Commando was a sure winner.
