It’s a 1973 1000cc four cylinder. It was built experimentally from Trident three-cylinder parts. It was good for more than 125mph but did not survive, it came just too late. It was also nicknamed the “Quadrant”.
I hear there are a few of these bikes around in europe that have been made by different people is there any where a person could have a motor made or buy one thankyou Russell Montgomery.
