Under The Hood
The new engine is, as you'd expect, a 90-degree V-twin, but it's lighter, smoother and cleaner than previous incarnations. This 1100cc version of Guzzi's familiar 90-degree transverse arrangement is said to produce around 88 hp, but the ingegnere of Mandello del Lario have imbued it with other improvements as well. For one, the alternator is no longer in front of the crankshaft-it's now nestled in the groove between the cylinders, making the engine shorter and more compact and improving weight distribution. In fact the whole engine bay has gone on a diet; the connecting rods are lighter to reduce mass, the piston rings are thinner and the pistons have shorter skirts and improved profiles. The metal cylinder head gaskets are new too, designed to improve heat transmission and to ensure that pressure from cylinder head studs remains even. Finally, the rocker covers are fresh, and play a big part in the visual appeal of the Griso's profile. All this is married to Guzzi's new single-sided swingarm (first seen on the Breva 1100) via a rejiggered six-speed gearbox.
