This is kinda long but ,by unfamiliar I mean any bike not 25 years old...Lol. So I'm pushing 50 and I've always preferred bikes from around the mid 80's and older. I grew up in the 70's/80's and thats what I really still prefer. Its hard for me to believe myself but im thinking of getting a newer bike. Hmm. By newer I mean something made in the last 8-10 yrs not "New" as that stuff is outta my range. Imtalking about $2000 or less. Where I need feedback is..is there a particular brand or year or size that was a know dud that I should stay away from?. Or maybe a bike that was great that I should look for? I've always been a Honda XR guy but Im looking at anything now. Lastly would be size. I am not gonna be a track ride,mostly trails and such. Are the 450's way heavier than the 250's. I want a comfortable easy to ride bike. Thanks for all replies.
