Special race, special motorbike? Mechanic Thomas Viola explains a few tricks on Matteo Cavallo's bike for The Valli Bergamasche. The “Valli”, is returning to the FIM Enduro World championships after four years.
Today’s Enduro bikes are strong enough for the “Valli”. They do not dread the infinite obstacles they have to beat on a track which has become part of history.
Thomas Viola, CH Racing Sherco Factory Racing’s team mechanic, shows us Matteo Cavallo’s motorcycle. “The bike is very similar to the one we used in Greece”, he says as he is looking at the 250 SEF Factory CH Racing which will have to face three rather challenging days. “We always follow a standard procedure where we pay particular attention to the preparation of the tyres and mousse.”
Thomas claims that almost all drivers choose standard tyres. The rear ones tend to be softer so they can give more support for example on loose rocks, while the front tyres are always new, having been used for one day at the most. Both the fork and posterior suspension have not been modified since the Greek race. They are still the Kayaba serial ones whose springs have been altered.
Here in Italy we do not only have one of the hardest, if not the hardest racecourse of the championships, but something else that makes a difference: the licence plate. These motorcycles are for road use and, like any other circulating vehicles, they need a plate. “We managed to develop a specific support for the licence plate. It is quite elastic, but at the same time it makes the fender more resistant in order to avoid it being hindered in any way by the presence of the plate.”
Any other tricks? “We installed an additional protection to the link which works like a slide: its smooth surface lets the motorcycle glide over whatever might get caught in it, for example a stone.”
We move away from Matteo’s bike for a moment in order for Thomas to show us a protection, which many drivers have chosen for the silencer, on another bike: “Not everyone wants it, because it makes the motorcycle vibrate and heat up a lot and this bothers some drivers” …it could, however, be useful for the Valli’s "Schiaccia Marmitte".
No prototypes or particular secrets, only a few modifications and special parts: the bikes used by this year’s best Enduro racers are all more or less, if not completely, the same as standard motorcycles.
Fast and indestructible, just like their riders.
