I saw a water cooled Triumph with a 2300 CC in line motor a few ago. Looks as if they’ve finally got past the verticle twin mentality.
Norton has a new V-4 bike, based on an italian design.
Triumph makes a bike called the Rocket. It looks very bad a$$, but I don’t need that much power. Afraid I’d kill myself.
