I have a super sweet Shifter Kart or Outlaw Kart 2006 Trx450r Engine Kit. Superior to the CRF450 in both torque, HP and of course electric start. Comes with EVERYTHING for it to run! Complete engine, factory exhaust, wire harness and all electronics, radiator. There is less than 10 original hours on it. Add gas and go $1500.00 to verified forum members. 407-222-95..one..five.
