i have them, you use the KTM SX 450 03 as they look better and are narrower and have a front brake hose guide included, black 5480800701030, white 5480800701020 you can get yellow in aftermarket from a company called racetech part TBKTMGH0300 nearly all plastic companies do black and of course orange, or if you want blue you need to go to the husaberg part 8000800700068 its a bigger plate and touches the tank on full lock this bigger plate in yellow 8000800700080. I trimmed the edges off the plate when i fitted them.
i use the KTM 450 SX in black, they suit 2003 to 2006 SX range, 07 changed the front guard and plate to suit but they will still fit, if you run a fender brace you need to trim the bottom of all these MX plates to fit.
Average price is $45 aud
