the thing with the sound is, once you get checked out, you are good for quite a while. my dad and brother both have ktm 200 excs (99) and came way in under the limit. when u pass, the give you a sticker and u put it on the bike, kinda like a green sticky. if you are looking for a bike for 750 bucks, you are gunna be looking at some mid 80s bikes, i would just save yourself in the end and put at LEAST 1500 into a bike. red stickies only come into play if u have a very new bike, 99 or newer i think, but correct me if i am wrong. with a red sticker you can only ride during half the year, the winter end of things. it is possible to get around red stickers via a number of ways, such as owning a 1925 ghetto bike, and just taking the green sticker off of that and putting it on the new bike. i have a 2001, and the guy who i got it from just said the dmv didnt say anything about it and gave him green. it is still in sketchy mode, so u will have to talk to people at dmv to get things right. but let me know when you get a bike, we will go tear it up fosho.
