- Bike: Suzuki DR650 ADV
The Britten company was fairly advanced on building a single cylinder motor when John passed away. Recently I brought this up on another forum and one of the other members happened to have been working with John and had details and even pics of it.
The cylinder was slanted rearwards to reduce the overall physical size of the motor, something several manufacturers now do including BMW with their 310cc single motor and Yamaha with some of their MX motors.
The Britten single was 608.2 cc and produced ~72Hp @ 9500 rpm. These photo’s show the the motor on a test bed with the Britten single cylinder and head bolted to what I’m told was a modified twin cylinder bottom end.
