New Moto Guzzi Stelvio

Passport

It should be called Stelvio, like the winding pass road in the Italian Alps, and it should be based on the concept of the BMW R 1200 GS. Sounds like the latest Guzzi project could give the word passport an entirely different meaning.

Despite a long continuity in the technical field, Moto Guzzi is always like-
which is good for a surprise. When news about the S.telvio, which should be located between the BMW R 1200 GS and Ducati Multistrada and should succeed the heavy quota, many thought the motorcycle would be shown at the Milan fair in November. But as early as the middle of the year, the Italian manufacturer was temporarily distancing itself from the Stelvio project. And in autumn instead presented a 940 named Custom and a Griso with a 1200 four-valve engine ?? both novelties that had not previously appeared in any bold speculation.

Instead, the Stelvio comes into play again when the most basic information about the two new engines is hardly available. With the clear announcement that it will be presented in autumn 2007 and that it will be built from March 2008. In two versions. On the one hand ?? a circle closes here ?? with the 940 two-valve valve. As Guzzi press spokesman Daniele Torresan reported to the MOTORRAD correspondent in Italy, Eva Breutel, this is the Norge engine, which has an unchanged bore of 95 millimeters, but a significantly shortened stroke (66 instead of 81.2 millimeters), exactly 936 cm3 reached. Thanks to the short stroke, the V2 has a particularly lively characteristic, produces around 75 hp and could replace all 850s in the Guzzi model range in the future.

The most promising candidate for the motorization of the large Stelvio is the four-valve 1200, which should produce 110 hp at a hefty 9500 rpm. The renowned Guzzi tuner Jens Hofmann, after all his experiences with the old 1000cc four-valve engines, still has certain doubts that this speed level can actually be maintained in large-scale production.
He is impressed by the modified arrangement of the timing chains, which now run behind the cylinders in the direction of travel. “The chain shafts no longer take away the cooling air from the cylinders as they did in the past,” says Hofmann and predicts better thermal stability in the exhaust area, which is subject to high levels of heat.

Another possibility would be to use Norge’s 93 hp 1200 two-valve engine as a drive for the Stelvio and to reserve the four-valve engine in an exclusive, significantly sportier version with 17-inch cast or forged wheels. That has not yet been decided, said Moto Guzzi spokesman Torresan. The computer retouches by Robert O’Brian shown here are obviously inspired by this hottest of all the Stelvio variants under discussion, which also comes close to the original approach. But the currently prevailing model policy direction is aimed more towards the R 1200 GS. So a more enduro-like and touring version with 19-inch front and 17-inch rear wheels in wire-spoke design.

The reason for this runs in the family. The Piaggio group of companies, which includes Moto Guzzi, Derbi and the scooter manufacturers Vespa and Piaggio as well as Aprilia. And this brand, which is clearly responsible for sports and high-tech in the entire group, will obviously bring a fast-paced fun bike in the foreseeable future, which the Stelvio shouldn’t get in the way. A more conservative design fits better with the image of the traditional manufacturer.
