Due to the California model that became so opulent with its top-end features, such as Brembo Series Oro braking system, steering damper, top-notch rims, and front suspension, but also with a high price, the maker introduced a poorer version to enhance the user base.
In 1999, the Italian bike maker introduced the no-frills Moto Guzzi California Jackal, a motorcycle suited for a wider range of riders, featuring basic features instead of high-end ones. In 2001, the bike became the California Stone and later was called just the Stone to be further differentiated on a marketing level.
In the aesthetic department, the bike had standard features, such as wire-spoke wheels, a dual exhaust system with a silencer on each side, twin rear shocks, a two-piece double seat, valanced fenders, a teardrop-shaped tank, and a round headlight with instruments mounted on top.
The bike was built around a double-cradle steel frame with a 45 mm Marzocchi telescopic fork and two 320 mm discs coupled to four-piston calipers handling the front wheel. In contrast, the rear wheel was controlled by twin shock absorbers and a 282 mm brake disc with a dual-piston caliper.
As for the power figures, the 2000 Moto Guzzi California Jackal had its soul brought to life by a 1,064cc four-stroke air-cooled V-twin engine mounted underneath the fuel tank, delivering 73 hp at 6,400 rpm and 94 Nm (69 lb-ft) torque at 5,000 rpm.
