I can't comment on the reliability, since I just got it, but I can tell you that I have ridden all brands and sizes of motorcycles since I was 14 yrs old...36 years ago, and this is the nicest handling cruiser I have ever ridden (handles like a sports bike). The 650cc has plenty of power, and I felt instantly comfortable, turns are a breeze. I take issue with others who say this is a "Beginner Bike". I am no beginner, I am an older rider with serious arthritic issues. Any excess weight on a bike is just something I don't need. I can back, park, turn, maneuver this S40 with no assistance. and cruise 75 mph. on the highway, effortlessly, and turns are no problem. It's just dang fun to ride!!!!! Seriously, I chose this bike over a Harley Dyna and am glad I did. My only complaint is the popping noise the big single piston engine makes upon down shifting. The sound may go away with time I'm told. It doesn't hurt anything, I'm assured, or I could change the exhaust. Suzuki really should take care of this problem. I called the dealership and found out it's very common, and not just with Suzuki, other makes do it, too. But I say, Suzuki! Fix it and make this The Perfect Bike!!
