I just picked up an XL cover from Costco Canada. $50 plus tax. They are sold online by Gears Canada. More expensive there but the fit on my R3T is almost perfect. Even has a flannel lining for the windshield and a strap behind the front wheel to tension it. Just an FYI.
Thanks for the suggestions guys. I need to cover to be a snug fit for an R3R. It wont have a touring screen or sissy bar, just a flyscreen so I don't want a too big cover and have it flapping about in a storm
I use a CycleShell, and let em tell you if you have to keep your bike outside this is the way to go. It is a pricey option but worth every cent to me...
