une sonorite incroyable! Guy Coulon's 300cc 6 cylinder motorcycle

Starting with two CBR250 engines, he machined his own cylinders and crankcase, machined a crankshaft from solid alloy and even designed his own gearbox.


He's the crew chief on the Tech3 Motogp team, and has the shop resources of a race team at his disposal.
