If you're planning on using the stock handlebars for this application, the crossbar is extremely close to the stabilizer and in some cases makes contact, requiring a slight "bow" be made to the stock crossbar, or you can purchase 7221 bars that have a bowed crossbar, OR convert to oversize bars, both of which can be done here online.
**SPECIAL NOTE:
2017 on KXF 250's and 2016 on KXF 450's may require slight filing to casting seams on each side of frame to fit frame bracket.
