Exactweld was a motorcycle produced from 1984 to 1987 by Guy Pearson and John Baldwin, at East Grinstead, Sussex.
Pearson and Baldwin wanted a good machine for the grand prix circuit and so produced this highly innovative motorcycle.
It had a 250cc water-cooled, tandem-twin, two-stroke engine with the cylinders inclined forward at 45 degrees. The compact unit had disc valves, on one or both sides of the crankcase, electronic ignition and a six-speed gearbox.
The novel chassis used the engine assembly to connect the front and rear suspension systems and had telescopic, pivoted forks in a sheet-alloy fabrication that bolted to the cylinder heads and carried the radiator. At the rear, the fork pivoted in a casting bolted to the back of the gearbox and was controlled by a single horizontal unit.
Although the machine was powerful and ran well, it took a lot of time and effort to produce and development was hard to carry out. They were eventually swamped by the Japanese market.
