Still, this is one of Guzzi's two best engines, alongside the California 1400's. It shudders and thuds and twists the bike under you as you blip the throttle. (These are good things, trust us on this.) Get the utterly numb, single-plate clutch engaged and the Griso pulls strongly right from the bottom, through a lean spot at 3,500 rpm, and then fearlessly again to the 8,500-rpm redline, making great if slightly restrained sounds the entire time. A pleasing low-frequency thrum turns to a tingle past 6,000 rpm, but the Griso is geared tall enough and is so amply endowed with torque that you may never have reason to experience it.
