If you are worried about maintenance costs, can read a repair manual, and know lefty-loosy from righty-tighty, I would seriously reccomend a Sportster just from my own experience with it. I blew a head gasket earlier this spring and ended up pulling everything off the engine down to the crankcase to replace all of the top end gaskets (the bike
is 20 years old). I took my time, kept everything clean and organized, and spend some time polishing the cases while I had the engine stripped- still took me less than 8hrs total time to do the job, about $60 in gaskets, and about $7 for a 12-pt 1/2" socket to remove the head bolts.
There are probably more factory and aftermarket parts available for sportsters than any other bike in existance.
Cons:
- Not a beginner bike despite the fact that Harley markets them as such- they are top heavy and take a bit more 'getting used to' than something similar like a Vulcan or Shadow.
-Some of them like mine, have a small tank (2.2gal) so only have a range of about 100 miles.
-have factory seats that aren't comfortable for long rides- I pretty much just ride mine from work to back (~35 mile each way) which isn't a problem, been on longer rides where after 60-75 miles you realy want to get off and stretch and give your tailbone a break. An aftermarket seat is the cure to this problem.
-Its a 'girls' bike- according to all of the harley marketing and various other assclowns who have never ridden one.
Pros:
-Plenty of power- really good accelleration at any speed, but not enough to wheelie or get out of control. Passing on the freeway is a breeze.
-They just look right- IMHO, a sportster is exactly what a motorcycle should look like.
-Very easy to work on. There are varying degrees of difficulty depending on how deep you dig into the motor/transmission, but there isn't anything that can't be done in your own garage with tools bought from Sears.
-Almost unlimited number of parts available and lots of information on the web. With carburated version (pre-2004), its very easy to change to better breathing exhaust/air cleaner and retune the carb by adjusting the idle mixture and/or rejetting (a complete carb noob like myself was able to do this easily).
That bbeing said, I would buy another Sportster, but I also really like the Honda VFR my buddy rides, I would buy one of those too in a heartbeat.
