General Comments:
The Suzuki V-Strom is the motorcycle for those who actually like to ride motorcycles rather than just keep them in the garage. Many claim that the bike is not sexy and not exciting enough. I would somewhat agree with the former, but definitely not with the latter. The motor is bulletproof and powerful enough for anything that any sane person would like to do. It does well on the highway (especially with an exchanged 16 T front sprocket) and has ample pulling power from low RPM. While the fairing may not be sexy, it is absolutely useful and well thought out. The V-Strom is a long-term love affair.
There are ample aftermarket options that anyone can use to customize and personalize the bike. Add a set of panniers (The Givi line offers excellent options) and your possibilities broaden from day rides and overnights to year long expeditions. I've found the bike no worse on fire and rougher dirt roads here in Colorado than any other street-oriented bike, but this one can be trail ready with a few of the before mentioned options, especially a skid plate. Anything that the V-Strom cannot do, and you are probably looking at dirt-oriented bikes such as the KLR or motocross.
If you want a motorcycle that is usable, generous, problem-free, and will serve you for many years, I can highly recommend the V-Strom.
