I think the bacon guy hit the nail on the head.
For years motorcyclists could be summed up into two large and outspoken culture groups. And the average joe didn't find either group appealing.
There was the harley 'biker' look with the gangland style riding colors. These guys are remembered by the Hells Angels fame. You had to prove that you were on Parole before lifting a chopper.
And then there was the 'crotch rocket' or 'hooligan group' with neon colored leathers. These guys are remembered for blasting by at twice the speed limit, and then stopping in a front wheel stand. You have to be under 25 to buy one and still have a girlfriend who's still in high school. And the girl only wear's tight tops and short shorts when riding on the back.
Also a seperate, yet a smaller group, were the 'giant bike' group which included the Aspencades and the full fairing Harleys. Those were regulated to retired folks. Only those with an AARP card could buy them. And those monsters are too large for the average joe to be interested in.
The DS bikes aren't so intimidating, and you can do everything with one. You can wear leathers or a levis jacket with a skull on the back, it doesn't matter. You still look like an average joe who doesn't know what the heck he's doing. There's no poseing required.
God bless the do anything DS bikes. Dorks like me can finally ride with all his camping gear, and be accepted as, well.... a dork on a dirtbike! We don't try to fit in. We're proud of not fitting in.
We call that adventure riding. 8)
