Twin Eye Project

Dit keer een nieuw projekt (Twin Eye Project – TEP). Het bouwen van een motorfiets op basis van een TONTI frame met behulp van 3 ingredienten.  

  • Handvaardigheid; zoveel mogelijk onderdelen in RVS maken zodat er een poetsvriendelijke motorfiets ontstaat. 
  • Gebruiksvriendelijk; in zowel zitpositie als bagagemogelijkheid en passend bij de vorm van de motor. 
  • Eigen gezicht; door onderdelen toe te passen die weinig voorkomen bij andere motoren. 

Aangezien dit een project is dat voortschrijdende inzichten tijdens de bouw oplevert, geeft Nesville aan dat het geruime tijd zal duren voordat deze Twin Eye klaar is, maar voor de nieuwsgierigen onder ons, hier toch enkele eerste foto’s geplaatst.

EICMA: Moto Guzzi Stelvio

With the much-anticipated Stelvio powered by an impressive “quattrovalvole” engine, Moto Guzzi offers its response to the challenge in the road-going maxi-enduro sector. This new machine is characterised by innovative technical and stylistic solutions that place it firmly in the lead in this category.

Moto Guzzi has carried out a full scale development project and reconfigured the “Quattrovalvole” engine. The exhaust system was renewed, then to tuned to “balance” with the new injection and intake set- ups. These modifications kept the power output in excess of 100 CV, but, at the same time, allowed smoother, more controlled delivery at low and medium revs. The engine also plays an important role as a stress bearing component in the new frame. This high tensile steel tubular twin cradle has been strengthened at the steering head and at the four engine mounting points.
The machine now boasts a slimmer, more tapered profile. Moto Guzzi’s maxi-enduro is one of the most compact machines in the sector and introduces numerous technical solutions and new items of equipment.
These include tubeless spoked wheels, anodised finishings, upside-down 50 mm forks with support brackets for radial caliper brakes and the magnificent satinised aluminium exhaust silencer.

Riders can now enjoy a adjustable saddle, adjustable windscreen and stow small objects in a new compartment alongside the tank. This compartment can be unlocked from a button on the handlebars.
As far as looks go, the front view of the Stelvio makes it stand out immediately from other Maxi Enduros. Two powerful round headlamps that are embedded in the nosecone dominate the front that tapers gracefully back to blend perfectly with the lines of the tank. The Stelvio will be available from the end of the year in white and red and black colour schemes. A version with ABS will also be available.

The new Moto Guzzi Stelvio completes the range renovation programme that, in little over 24 months, has seen this legendary marque regain all its past splendour.
What was missing and what the public were impatiently waiting for now is now available in the form of a complete motorcycle. This is the Italian answer to the demand for a multi-purpose maxi-enduro machine that can adapt to all conditions and restore the pleasure of riding.

A machine with these characteristics could not have been a descendant of previous models but was created as part of a totally new project. It is the direct result of a long and painstaking research and development programme that involved countless riders of all types and widely differing conditions of use. Moto Guzzi undertook this challenge with one particular key element already decided upon: the new “Quattrovalvole” engine.
Docile and powerful at low and medium revs, this twin-cylinder, single raised cam transverse unit is housed in a slender tubular frame that appears so fundamental as to make even specialists in off-roading look again.

Riders will appreciate the absorption characteristics of the 50 mm upside-down forks and the traction offered by the combined action of the rear single swingarm and the progressive rear suspension system, not to mention the superb CA.R.C (reactive shaft drive) final drive. If the fact that the Stelvio is very much at its ease on deceptive surfaces with little adhesion is down to the superb frame design, its decreased weight and smooth power delivery; its vocation as a tourer is highlighted in the many little details that were specifically included to make daily use sheer pleasure. The windscreen and saddle can be adjusted, side bags come as standard and the pillion passenger’s part of the saddle is more than comfortable in both size and shape.
A small storage compartment that can be unlocked from the handlebars has been positioned between the screen and tank.It is the little details that make all the difference and make riding this machine such a pleasure.

With over 100 CV on tap, the machine offers superb performance while the sound it makes says it all. It goes without saying that safety is at the forefront with powerful radial brake calipers housing twin parallel pistons. Besides this Moto Guzzi Maxi-Enduro’s performance and technology, there is another element that sets it apart from the competition: its beauty. The Moto Guzzi Stelvio captivates with its front end looks and slender profile. The aggressive Guzzi red or sophisticated white colour schemes catch the eye and are set off by the anodised tubeless spoked wheels.
