Chainsawmotorcycle Model

The Dolmette motorcycle uses the power of 24 on-board chainsaw engines to create one heckuva promotional item –

The heart of the combined power plant is the central drive belt casing of aluminium construction. As well as encasing the eleven belts used to couple up the individual engines, it also houses the exhaust ducts for the cooling air. Twelve engines are mounted in two rows of six on either side of the drive belt casing. Each engine is held in place by means of two threaded studs that normally serve to secure the guide bar to the chainsaw power head. The individual motors are coupled together in sets of three by means of a double-sided drive belt, making up eight modules in all. The individual engines are not rigidly connected; instead they deliver their torque through the centrifugal clutch that is a standard feature of every chainsaw.

While certainly visually impressive, it seems this beast didn’t fair so well in a demo race where the pit crew didn’t have time to start four of the engines – Dolmette Technical Facts [via Hacked Gadgets]
