Of course it counts, but it only counts to those few who actually look at the series. If you ask average Joe Bloggs on Mr Average bike in the street if he knew that a Guzzi won at Daytona he'd say either, "what, they got a Cali to get round that track in one piece?!" or "what's a Guzzi?!"
"but how many people are looking to but $20,000 bikes?"
With the current exchange rate, that's only £10,000, given that the Rosso Corsa was about £9,500 new...
The best analogy I've heard so far is that Ducati are like Ferrari and Guzzi are like Maserati: Ducati are the Hyper-sports machines, and Guzzi are (should be) the 'classic' sports bikes that are good on everyday roads. We're not asking for 180bhp at the rear wheel, we're asking for an old school sports bike that looks the part, like the MGS, makes over 100bhp at the rear wheel and can handle well. Essentially the what the Buell is to Harley...
Just my thoughts...
