I have had no problems whatsoever with the bike as originally delivered. I have had some problems with certain after market items, but this isn't Suzuki's fault, is it?
Overall I think this is probably the best road motorcycle on the market for the asking price. You can ride it as a naked bike, with a small shield only, or load it with a large shield and bags for touring. In any configuration it will fill the bill smoothly and confidently. I love this bike!
I did, however, change several things on the bike almost immediately after purchasing it. This was not because of any inherent factory faults, but because of personal fit and fussiness considerations. I did, after all, know that these changes might be needed to suit my tastes before I even drove the bike off the dealer's lot.
I didn't like the forward foot position, so changed to very long-tailed floorboards so that my feet could be below my thighs... the traditional English position. Shift and brake pedals were not moved and this has worked out fine.
The handlebars seemed somewhat low to me (I'm short legged and long waisted) and this was confirmed later as I would get severe pains in my left shoulder after about half an hour's riding. This pain would not subside until I was stopped and afoot for a while. Not acceptable. Raise the bars? Not an easy task on an M50 so I sought out a lower seat. I found a heated one (big bonus there!) that lowered my butt 1 1/2 inches which solved the pain problem and greatly extended the comfortable riding season.
No complaint, just a tip, J.C. Whitney sells an $8 (ea) mirror extension and anti-vibration stud that works great. It provides a greater view (it's higher, after all) of the road behind you. Highly recommended item.
Viva M50!
What kind of aftermarket seat did you end up purchasing that satisfied your requirements for riding position?
