My son bought a 450 suzuki for $500 in NYC. (Mom won't let him have a sportbike there) He put on new tires, liberated the exhaust, K&N filters, narrowed and flipped the handle bars, then sent the seat to Sargent Seats in Florida.
For $1000 - 1100 it's a great little bike. It spanks my brother's 80 cube Harley.
