Go to the bike show taking place right now at the Cardinals stadium. You don't want to miss it; trust me.
I like the sprots bikes... I REALLY like the Ducati 695 Monster the naked bike. Other then that I do like the look of the CBR and the Kawasaki Ninja bikes. So far the Ducati is my favorit bike that I have seen. I just don't know what the difference is between all of the bikes and what is the positive and negative of the different makes. Or are they all just like a car, (no difference in how the ride feel is and the service cost is between a Ford Focus and a Chevy Cobalt) type thing.Kinda hard to answer this since you have not told us anything about what type of bikes you like. But if the Ducati is not your thing then maybe you should check out the V-star or Shadow line of bikes in the 650 to 750 range. Nice cruisers with power to stay with the bigger cruisers.
You may also want to look at Triumph's Speed Triple or Street Triple. Styling like the Monster, but with less maintenance.
Check out the Ducati boards, but I'm thinking the valve adjustment intervals were just increased to 7,500 miles. It was 15K on my Yamaha. Chain lube and adjusting are about every 3-400 miles, but that's a do-it-yourselfer.So are the maintanence cost on some brands of bikes much higher then the others? How often do i need to maintain them and what is the average cost? I know on cars the major maintanence is on 30k and 60k miles.
