First off, let me say that I am a mechanical moron!

And I have owned a Rebel and currently own an '03 Savage ... loved the Rebel ... very nice little Bike! Essentially bulletproof and easy to handle ... big plus is that it literally sips fuel!
Sold the Reb and bought the LS ... was looking for a small Rebel-like Bike with more punch ... and seeing as the CMX450 Rebel is no longer in production, the Savage fit that bill TOTALLY! I am completely 110% in love with my Savage!! And yes, I literally have to beat people away from it at local Bike Nite!
Now back to the "mechanical moron" part ... when I got into Bikes, I hardly knew which end of a wrench was which ... but figured, if I was gonna Ride and not pay thru the nose for every little bit of maintenance, then I'd better start learnin'!
So, depite generally being scared sh!tless of screwing stuff up, I took the bull by the horns (or Bike by the bars!), read as much as I could (this website is an awesome resource!) and bought Clymer manuals ... am still a mech. moron, but here's some of the stuff I've done so far (and if I can do it then anyone can believe me!);
Rebel - change oil & filter, adjust clutch, replace spark plugs and remove/reinstall battery, remove/reinstall front wheel, clean, adjust & lube drive chain.
Savage - change oil & filter, adjust clutch, remove/reinstall gas tank, remove/reinstall petc0ck, replace spark plug, replace front brake pads, remove/reinstall battery, adjust handlebars, jurry-rig repair to clutch lever housing which I busted when adjusting handlebars

... repair works great BTW!

All Bikes have their maintenance quirks no matter what you buy ... best of luck with your ultimate choice!
