Take a run of the mill CB750, remove all the bad bits and replace them with good bits and what do you have? A Seeley, most likely.
Colin Seeley was a British champion sidecar racer with an idea. Put a British frame on a Japanese motorcycle and have the best of both worlds. Between 1975 and 1978 he built 300 of them.
The frame is a duplex tube cradle that is hand matched and welded. The frame is 25 pounds lighter than the Honda and is considerably stronger. The motor is a stock CB750, and the front forks are also from Honda. The brakes are from Lockeed, the wheels from Lester and the rear suspension from Girling. Body work is completely from Seeley.
Fit and finish on the Seeley is wonderful. There are lots of ‘one off’ pieces. The Lester wheels had to be machined to match up with the Honda hubs, and other pieces had to be designed and built to bring the various systems together.
This particular bike has a full fairing as opposed to a simple fly screen. The ad says “lots of history” although I couldn’t find it. It’s still a Seeley and if you want more information or need it for your collection you can find it right here on Cycle Trader in North Mankato, Minnesota for $13,995.
