Hi guys! Have a 2 month old SR/F Premium and I'm thinking about putting a level 2 charger in my garage, accessing 220V will not be a problem. Now that these bikes have been around awhile I'm sure there are some preferred suppliers that you guys have discovered. There are tons of automotive J1772 compatible units on sites like Amazon for $200-$400, yet some of these say "not compatible with motorcycles? Educate me, please. Thanks
