2004 Moto Guzzi Stone
Dedicated to all those who love the essence of things
with nothing superfluous, the Stone is a motorcycle
in the pure state. Trim clean lines, classic minimalist
design, the temperament of a genuine Moto Guzzi. A
unique personality and charisma, successfully combining
tradition and innovation. The concept is clear from
the engine, the unmistakable 90° V-Twin in its most
up-to-date version with environmentally friendly three-way
catalytic converter with Lambda sensor and silent
hydraulic tappets. Thanks to its handling and agility,
the Stone is particularly suited for about-town use.
The riding position is natural, with the classical
set-back handlebars and set-forward footpegs.
The high tensile steel frame is rigid and follows
the rider's intentions with consistently predictable
behaviour. The front suspension with robust 45 mm
inners is a guarantee of precise entry into bends
and, with the 130 mm travel, absorbs uneven road surfaces.
The double shock absorber adjustable in preload guarantees
stability and comfort, adapting the set-up of the
bike to load and route.
The shaft drive is also particularly suitable for
everyday use, even about town, as it is silent, has
no exposed parts and is thus cleaner, is ultra-reliable
and requires practically no maintenance. In short,
all characteristics which translate into top-class
travelling comfort in all conditions. A modern expression
of the Moto Guzzi spirit, the Stone is available in
three refined colours - Rosso Race, Nero Shadow and
Grigio Platino.
