Feast your eyes on the Revolution® engine and there's no mistaking its roots. This is authentic Harley-Davidson style through and through with an attention to detail you won't find from any other motorcycle company. Deep black cylinders and rocker covers complete the dark look, while the machined cooling fin tips on the cylinder heads give it a stripped down, raw metal finish. It's a jewel machined out of metal. Pure. Dripping with power. From the classic edge of the cooling fins to the clean lines of cases and covers—the Revolution® engine makes an ironclad statement to holding on to what's right and staying true to what satisfies the rider.
