Avon,avon,avon....I like avon myself. When I first started building bike, my whole intention was that look your after. The name doesn't come to mind but I know what your describing. The "fat tire motorcycle look" is what I found with google.
I've done it with my Harley, its called "the dark side" where you run a rear tire up front in the opposite direction of rotation for "reasons".
Sounds weird, I know, but my experience so far has been a smooth ,stable,
zero death wobble ride ,with a badass look.
The look Iv'e got on the Max is definitly the fat tire out back(300) ,but I still would have to source the fat wheel/tire up front to bring it full circle.
Lookin at it, it sure would be cool if I did it, fat close fender too!
SHHhhhh! The mod monkey's stirring
