I bought this bike used and the previous owner had installed a power commander as well as Vance and Hines straight shots. During the summer, this is my daily driver. I am a mountain bike racer and take it to the venues so I'll frequently have 200-500 mile weekends. Laden down with my bike and all the necessary gear the bike handles amazing and aside from needing additional/alternate foot rests, the comfort, ergonomically speaking, is superb. I have never had a problem with the bike mechanically and look forward to many more trouble free miles. Performance wise, keeping in mind that I am 155 and will frequently be carrying up to 50-70 pounds worth of gear I am extremely happy with the power and efficiency. The front brake is adequate for all intents and purposes however the rear leaves me longing for a disc. ABS would also be a handy feature, however that would drive the cost up, which was a primary consideration in my purchasing decision. As far as comfort goes, I enjoy riding the bike when it is laden with gear however, when I ride solo I have to take care to not drink too much coffee or soda before I go out - the suspension w/ a 155 pound rider is a bladder buster. I would definitely appreciate a fair amount of rider adjustability beyond preload, including spring rate, compression and rebound damping. Bumps, even small ones will frequently jolt me off of my seat. Because of cost/availability of an air spring for the bike, I'll be evaluating different saddle options. I have not had any quality issues to date. I am very happy with the fit and finish of the bike. I appreciate that it has some chrome but not a lot and while I have a distaste for plastic, appreciate that it keeps the weight/expense down and is a contributing factor to the 50-52 mpg I currently achieve. Another missing feature is accessory power. I now use a GPS and powering it off of the bike is a challenge. It would certainly have been nice if this purchase wouldn't have to be made in the aftermarket. This would also be handy to power heated gloves/pants/jacket. Included with comfort is my comfort level with the low-beam headlights which are over-driven @ approximately 45mph. I'll likely be installing a light bar in the future for better visibility and to increase my comfort level when going out at night. Overall I am very happy with my purchase. This is my first bike and it has made me hate my car. It currently has 8000 miles and I hope to get at least 40K on it before I even consider a new ride. At roughly 7K a year I hope to have it for at least another 5-6 years before I begin to lust after a new model.
