the 1800 is heavy and somewhat unweildy at lower/town speeds
but i have a feeling you're going to be looking at a 1300. i had one for a few years and loved it. actually really miss it. Very reliable bike, easy to work on, easy to ride after you get used to it and lots of power.
Googl3it can probably weigh in on possible problems to look for, but during the time i had mine i beat the snot out of it constantly bouncing off the rev limiter for thousands of miles with no issue.
