Mark Series 348cc ohv flat twin || 340Ib || 65mpg || 75mph || 1949-51

These smart little twins are hard to find for sale and rarely seen on the road. The engineering is remarkably innovative, with their own take on suspension at both ends, using torsion bars in the forks and in the lower frame tubes. The drive to the rear is by chain, despite the BMW-style flat twin layout. Fine handling for their day, they can be a little fragile in the power dept. The engines are sweet, smooth, and gentle. The initial T35 model had a few teething troubles. The Mk3 Sports is the acknowledged one to have. 80-Plus and 90-Plus sporting versions are faster and boast better brakes.
