The Appeal

Colin Seeley was a man used to being close to the ground. As a pre-eminent 70s sidecar racer it is perhaps no surprise that when he began work on a bespoke frame for the CB750, he focussed on lowering the centre of gravity, reducing weight and improving the handling.

He began work on his bike after honing his chassis skills with the Brabham F1 team. He chose the CB750 because it was one of the most popular sporting bikes of the time, helped by the phenomenal performance of its in-line four.

Just 300 CB750 ‘Seeley Specials’ were built, some as complete bikes and some sold as kits. All are highly sought after for that tempting blend of clever frame and Honda power. This 1980 example was one of the last built and must be one of the most interesting remaining.

It has been in the hands of the current keeper since the day it was first registered. In its 45 years, it has covered less than 40,000 miles and it has always been dry stored in a locked garage. It is a proper ‘timewarp’ bike that is in highly original, beautifully preserved and unrestored condition. Quite frankly, it is magnificent.

Recent work has included a full engine rebuild and general overhaul totalling £4,219. The result is a matching-numbers bike the like of which we suspect it will be very hard to replicate. All of which is another way of saying: don’t miss this opportunity.

The vendor says:

“Purchased in June 1980 at Ryes of Fulham in London. I am the only owner. Stored in a locked garage all its life.

“It is a pleasure to ride! A classic bike which loves the open road, plenty of power! Must be ridden to be appreciated!”
