Most of the bikes I see are just before or after going up Old Tunnel, so, Nice neighborhood? I guess so but it is still Oakland.
Gixxers may outsell Ducatis in the rest of the country but I think you'd find different numbers in the Bay Area.
Down in Phoenix, I saw two 1098s in 5 years but gixxers were everywhere. Out here, it is a totally different story. Just like people in the Bay Area are vain enough that they spend more time in the gym than anywhere in the country, they also like to show off how sophisticated they are.
