I think this might be sticky worthy, Ive personally read this like 3 times over, it is awsome.
Read this BEFORE buying a bike, it will save you alot of headaches AND money!
kinda late edit:
REMEMBER: if you are going to buy the bike from a dealer, they might try really hard to get you to buy a bigger bike (engine size) becuase the more expensive bike, the more money they make on it (they make a % of price). If they try that, they are NOT CONSERNED with your saftey, and vote with your wallet and buy from somewhere else! Let them go out of buisness!
