Engine
The XS400 featured a four-stroke, air-cooled, overhead-cam engine that is commonly called a "parallel twin". While the twin cylinders are indeed parallel, the two pistons are offset 180 degrees of crankshaft rotation -- this arrangement greatly reduces linear vibration at the cost of some axial vibration. The 392 cc (23.9 cu in) engine produced 36 bhp (27 kW) @ 8100 rpm.

“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.”
