The Revolution X is a 749cc four-stroke engine that is configured as a liquid-cooled 60-degree V-Twin with chain-driven single overhead camshafts (on per cylinder) operating four valves each. The RevX also gets roller rockers with screw adjusters, keeping with the current trend of friction reduction. A lot of work on this engine was done by AVL, but this construction format is actually very similar to the V-Rod which came in 2001 bearing a huge Porsche influence as Harley's first liquid-cooled engine and motorcycle.

Harley has moved away from tradition with the RevX engine. For example, the 60-degree included angle of the V -- 45 is the traditional angle -- was used to lower the height of the wet sump engine. This helped to create the low seat height. It also lowers the center of gravity which makes the handling better and low speed feel more secure and stable, all critical elements for new riders to be able to find confidence in their machines.
Above the crankcase are two separate aluminum cylinders with iron cylinder liners. In fact, the sole difference between the 500cc and 750cc versions of the Revolution X is the bore. The 749cc uses a 85mm bore while the 500 uses a 69mm bore. Both have a 66m stroke. Both engines have the same 8000rpm redline with the 750's peak power likely to be just under 55PS at about 7500rpm. Torque is claimed to be 65Nm at 4000rpm, which promises quick acceleration as well as the typical rideability that Harleys are famous for.

The Revolution X will be built in India and currently the Indian 500cc plan is on the back burner. The Street 500 is being built at the Harley plant in Kansas City for domestic consumption in the USA. Harley India will export the Street to three European countries initially with exports to SE Asia are soon to come.
