Price of admission is hard to swallow, but very few if any air-cooled, two-valve Ducatis in the world crank out this kind of power. The $49,900 M4 is powered by an 1100cc engine producing 107 horsepower and 84 foot-pounds of peak torque (about 30 and 16 more than a stock 1100 EVO). If you’re spending that kind of coin, you may as well step up to the $69,900 One Shot and its 1200cc mill, which incorporates a billet stroker crank, Ti rods, Ti hardware and NCR-EVR slipper clutch. With 132 hp and 105 ft.-lb. of peak torque, it has a better power-to-weight ratio than the mighty BMW S1000RR.
