Even powder coated they will still be spoke wheels. Check out RC Components. They make a lot of nice wheels to fit your 900 Classic LT. You could also save yourself a few bucks and buy a stock 900 Custom rear wheel from the parts for sale section of this forum from a fellow member since the rear wheel is mostly hid behind your saddlebags and pick a front wheel you like from RC Components. Then your spoke wheel issues are gone and you can run your tires tubeless as a bonus (no more pinched tubes).
