There is this cool stuff called "humor"...it is when people tease each and say things that stretch reality in interst of humor or being funny. Sometimes it manifest itself in "sarcasim"...you have to be able to smell that though.
I think the teasing of Tallguy is not that his bike is clean in that picture, or that a person cleans their bike, but rather that people ride GS's and GSA's that never get used for thier intended purpose...both kinds of roads, paved AND dirt...hence the "dual sport" designation.....and those "dual sports" are not 1} Short drives to the strip mall and 2} competitive coffee drinking.
At least in my case, I am just teasing you. your bike is beautiful. Ride it how you wish. But remember, they do NEED to at least GET dirty once in a while so have something to clean.
