Up for sale is a lightly used Cylinder Works 366cc big bore kit with mapped ECU for a 2016-2018 KTM 350 SX-F or XC-F. This was used on a healthy 2016 350 SX-F for less than 20 hours. The only item you will need is the matching big bore gasket kit from Cylinder Works. Tokyo Mods mapped the ECU to match the 366cc kit. Everything is in excellent working condition. The original crosshatching on the cylinder wall is still even and full. There are only some minor, normal vertical scores from the piston skirt. No scratches, pitting, cracks, or excess wear. The piston includes the ring, wrist pin, and cir clips. This assembly is ready to mount and ride! Look closely at the pictures. What you see is what you get!
