well it depends, by I agree with onesojourner for the most part. If your 15 yrs old and about 120 lbs then go for it, it will last a few season spend a lil money modded then move up if you like it. If your older and heavier and can also save up or take a loan out i would go for the sj. I bought a 440 at 14, dropped in a 550 at 15 rode that and spend a ton modding it until I was 18, now this spring I just picked up a 93 sj 650 and now that will be my new money pit and save the 550 for girlfriend and friends or possibly a backup.
