As before, the 'Busa's ergos are roomy and accommodating for the 6-foot-plus crowd. Engine vibration is subdued below 4500 rpm, but it seeps through the bars, tank and pegs once you exceed an indicated 85 mph in sixth gear. Wind protection has been improved with an 18mm-taller windscreen that results in a remarkably low amount of turbulence. An upgraded KYB inverted-cartridge fork now has black Diamond-Like Coating on its 43mm stanchion tubes, providing more supple action and an improved freeway ride. Though the new 'Busa tips into corners at street-legal speeds with reasonable ease, it weighs-in at 585 pounds with its 5.5-gallon fuel tank topped up. That makes for an aerobic workout when hustling the bike along a twisty road at speed. Still, for $11,999, there may not be a quicker—or more thrilling—means of getting in shape.
