My only suggestion when deciding on a F6B is to get the dealer to move it out of the showroom and into the parking lot then sit it it and maneuver back and forth using just your legs.
Then get off and push it around using your arms and legs going forward then backwards.
I love mine but it is a heavy pig to maneuver. The new 2018 does not have reverse unless you buy the full Wing Tourer.
You just have to remember not to park with your front wheel pointing downhill.
I got a great deal on a 2016 and have no regrets. The engine alone is worth the price admission.
