Nothing so far.
I still own my Kawasaki ZX10R, so it's not a "previous" motorcycle.
I purchased the Honda FSC600 Silver Wing after research and consulting with current owners. I have nothing but good things to say about the Silver Wing. I have purposely taken it into tight slow speed turns, as well as high speed turns. I've tested its top speed, acceleration, hard braking, and put its storage to the limit. It rides well in every situation.
My plan is to use it as a daily commuter by highway for minimum 160 miles/day. I haven't moved yet, so I'm testing everything about it now. I'm very happy with my purchase!
The Silver Wing is the third motorcycle I've owned. It's fun, easily maneuverable, and has plenty of storage.
I full throttled it from stop, and it does not lift off the ground.
The stock seat is comfortable. The ride is smooth at slow and high speeds.
The fuel reserve is near one gallon, and I got 135 miles of hard riding from a tank before the reserve, I'm still good for another 40 miles after that.
You can rest your feet flat or at an angle. Plenty comfortable.
I've had more people stop and question me about this bike more than any other. I've known people to own as many as 5 Silver Wings. Personally, I love it and I'll buy another one.
You've done an excellent job of identifying the FSC 600's virtues. I have owned mine since 2002, when Japan first began exporting them to the United States.
My first mechanized two wheeler was a Honda Elite CH80, which was a good bike to learn on. Very simple to operate and fun to ride, however not powerful enough to ride on major roadways. It's top speed was about 42mph, however, it was not a good idea to operate the bike at that speed for any length of time.
The CH 80 cruised nicely at about 35 mph.
I still own the Silverwing and would highly recommend it to someone who's grown tired of shifting gears on their motorcycle, or simply wants to move up from a scooter.
One caveat here: The Silverwing is a powerful motorcycle which is capable of more than 100mph, and must be taken very seriously. In the early days there were several posts on a Silverwing forum from riders who were small in stature, breaking bones when their FSC 600 got away from them.
It turned out to be more bike than they could handle.
Several bikers purchased FSC 600's for their wives thinking that they would be safe on the Silverwing, only to find that they got into trouble in a big hurry.
I am aware of a few people who were seriously injured when crashing their Silverwings into other vehicles. In fact, the 'Wing can be a handful in tight places like one's own driveway, when a bit too much throttle and insufficient grip on the handlebars can lead to taking a spill or crashing into a parked car.
Other than these caveats, the Silverwing has been a pleasure to own and operate, and has given this author a tremendous amount of enjoyment.
Highly recommended!
