As stated, any 7/8 bar will bolt right up to your KX. If your at all picky, finding the bend your comfortable with can be a mind-racking experience. Consider this: your height, the taller you are...the taller the bar (and if you're a stand-up or sit-down rider, that weighs in there too) rise: amount the end of the bar is sweeping up or down, and sweep: weather the end of the bar goes away from you or towards you. Even at a dealer that has a big stock, you really won't get a feel till they're mounted up. The Yamaha/MC/Reed bend is very popular. If the KX bend is a copy of the stock bars (most likely) I always found they had too much sweep (blisters on the thumbs) I probably made it worse huh?
