Got my new 550 yesterday,and rode 230 miles,mix of city and highway.Previously rode all Burgmans and the BMW C400X.
Here are my first impressions
Positives:
Great engine,lots of torque,great acceleration.
Superb brakes,both rear and front.
Stable at highway speeds.Rode at 85 for a stretch,and could have easily gone to 90-100 without a problem.Heavy enough that you don't get strong buffeting when being passed by a semi rig.
Great lcd panel,all info easily readable,and easy to cycle through different menus.
Good fit and finish.
Nice stock exhaust sound!
Easy to maneuver in town
Negatives:
Seating position is so-so.I'm 5'7 and found myself having to lean into the handlebars,with resulting neck pain after riding for a while.With my height and inseam no flat footing at stops.Manageable tiptoeing.
Wish the butt bumper was taller with more support and with more adjustment points.
Windshield is a joke.Very bad buffeting on my helmet at highway speeds.Will look for an aftermarket option.
3 gallon gas tank on a scooter this large!Didn't get a good reading on m/g,but be prepared for frequent gas stops.
The main switch that controls the gas tank,seat opening,lock and unlock is really complicated.Read the manual several times and still haven't got he hang of it.
There's an app for the scooter,that allows you to send info from your phone to the front panel.Haven't tried it yet.
Top box will be essential for long trips.Under seat capacity is limited.
Overall I find it to be good value for money,so far.Not a cheap scooter,but so far beats the big Burgman,or BMW.
