Going to look at a bike Sunday

The XS650 is a vibrating bastard. Remember...you'll save on gas, but how many miles do you have to ride at $X savings to justify paying for the bike? The thing to consider too:You'll get about 5-8K miles per rear tire (@$100-150 each) and buying chains sprockets (mileage may vary, figure $150 for both) and all that, including oil changes, valve adjustments, etc. plus you may or may not be willing to ride all year.

The XS is reliable, and most parts you'll need are still available (It's a popular bike among flat-trackers) but you gotta find out what the failure is, too. Could be a CDI ($~200) or something even more expensive. Fun to ride? I didn't care for it.
