Yamaha MT-10

Ultra-lightweight, compact, 998 cc, DOHC, 16-valve (4-valves / cyl.), liquid-cooled, in-line four-cylinder engine with “crossplane” style crankshaft. The MT-10 engine is EU-4 emissions compliant (European Union emission standards … this is a very clean engine!)

The key components of this cutting edge engine design are the “crossplane” crankshaft and an uneven firing order. Both of these features are used on Yamaha’s championship winning R1. The MT-10’s crossplane crankshaft locates the center two rods at a 90 degree plane from the outer cylinders. Instead of the crank pins aligned on the same plane (a straight line drawn through the center of the crankshaft), they align on 2 planes in the form of a cross… or “crossplane”. Working in conjunction with the crossplane crank is an uneven firing order. This MT-10 engine fires 1,3,2,4 cylinders and the firing intervals are uneven at 270 / 180/ 90 / 180 degrees. What all this means to the rider is the most linear torque possible with amazing throttle control.
