My take----handling problems real or imagined----not in front---this after 2 new SilverWings and lots of miles.....but related to rearward weight bias.....adding weight above and behind rear axle center(top box in most cases).
Most noticed at slow parking lot speeds or heavy traffic.
Not believing in too many mods---my Current Silverwing has GIVI adjustable shield/fork protectors/NEP throttle stop and GIVI passenger back rest. Been as far as Alaska and back---it rides well. Always thinking about next bike----but not much out there now that works any better than SilverWing----but BMW GT has better wind control.
Front end fine---this is a scooter, ridden as scooter it is fine. My take after 60 years of riding and over 75 new bikes is: long run, cheaper to get another bike. And at this point SilverWing is old design
