Smart expertly kick-starts the SS, pulls the right-side shifter up for first and enters the track. The motorcycle is obscenely loud, even by early-'70s standards, and the combined thrashing of the gear-driven cams, the intense intake chuffing and the bark of the straight-through Conti mufflers is definitely plug-your-ears painful at close range. No wonder Maggie Smart, Paul's wife and the sister of the late, great Barry Sheene, had reminded him to wear his earplugs. Smart laps, well, smartly, on the Super Sport, but not quite at the same pace as on the racer. It's the brakes mostly. Italian Scarab front calipers-cheap knockoffs of the factory racer's Lockheeds-became standard equipment on production Super Sports and never offered the same performance or feel as the originals. Besides that, the Super Sport doesn't have the Imola-spec camshafts, bold cylinder-head development, straight-cut primary gears, efficient racing fairing or light weight of the factory bikes. Even so, its DNA remains intact.
