When I purchased Avon tires last year, I saw where motoprosports listed whitewalls as an option. I believe they have whitewalls in the size ba rims require. Look in the "accessories" section under post avon 4 tba. Grump posted the sizes and a site location. Metzeler also makes whitewalls. My take from reading past threads is that the Metzeler whitewall is wider on the "white" part than the Avon. Some people here have whitewalls, look in the photoposts. I believe they are mostly Metzelers. Whitewallers better chime in here!
IMHO Whitewalls can really set a bike off, provided it has the right accessories. On my bike however, whitewalls would have required I also glue a shag rug to the tank top & hang some fuzzy dice off the triple tree!!!!!!
Good luck
