Like others here, due to age and health, I decided to downsize from my 2006 Royal Star Tour Deluxe to a Royal Enfield Super Meteor 650. Loosing over 300# is welcomed but I'm not thrilled about loosing the drive shaft for a chain. While this new bike is only rated for 47HP, many reviewers say that it has no problem cruising at 75mph. And smoothly too.
Being an air/oil cooled parallel twin with screw and locknut valve adjusters, maintenance should be a breeze. Time will tell. It does come with a three-year, unlimited mile warranty.
Still being winter here in the Denver area, I haven't ridden it much, but the few miles I have, have been enjoyable.
