2003 Moto Guzzi California Stone, NICE BIKE - The Moto Guzzi California Stone, a bike that takes bedrock simplicity to new heights. Featuring a new seat design and re-calibrated rear shocks with new springs for better comfort. Tough 30 mm diameter handlebars with precision controls. A new gearbox with more precise shifting. And the classic 90 V-twin still has the most torque in its class. Four new colors give new meaning to the phrase, 'earth tones.' California Stone: the bare essentials never looked so good, or handled so well.
