Vortex X10 ECU Yamaha YZ450 can be flashed for YZ250F
Going cheap! Save yourself the best part of $1000. One of the best additions to any bike - greatly improves response and delivery of power. 10 adjustable map settings. Used on my 2016 YZ450F (16-17) but can be flashed for YZ250F too. Will send at buyer's expense (likely to be $15 or less)
