This bike is brand new, garage kept and never ridden. It has all of the performance upgrades, programmable ECU, Tuner to change the maps in the ECU, restrictors removed from exhaust and intake, larger rear sprocket and new high dollar chain. 2015 had the new frame same as the YZ and has the upgrades to run like the YZ. This bike is in brand new condition and I mean same as it was when it was on the show room floor, you will not find a better deal anywhere ever.
