A custom motorcycle with Maserati power was featured on RideApart two days ago. Created by Chris Barber of Crossbreed Cycles, as you can see in the photo, it uses the V6 engine that Maserati developed for the Citroën SM and which was also used in the Maserati Merak.
Chris chose the V6 engine for his custom bike because of the short length (13 inches front to rear) and features such as the cam chains running through the middle of the engine rather than the end, and the water and oil pumps being internal. As such, the compact, self-contained design of the engine makes it a particularly good choice for a motorcycle.
The motorcycle drivetrain had to be adapted to the Maserati engine by using a Baker Frankentranny, complete with a kick-start, an S&S clutch and custom primary drive chain. All of these components share oil from the engine sump. A Ducati ST2 alternator and rotor provide power and ignition.
