D.I.D 520DZ2 Gold Chain & Sprocket Kit - 13T/49T For KTM 250 SX 2005-2015

About This Product

KTM 250 SX owners, this D.I.D chain and sprocket kit is exactly what you need for reliable performance on the track! The gold 520DZ2 non-O-ring chain looks fantastic and is built to last - with a projected wear life that's twice as long as the previous 520DZ model and four times longer than standard chains. The 13-tooth front and 49-tooth rear sprocket combination gives you that +1 tooth over stock for slightly different gearing that many riders prefer. The SDH pin treatment creates an extremely hard chromium carbide layer while maintaining a soft inner core, resulting in outstanding impact strength and shock absorption. I installed this kit on my 2012 KTM 250 SX, and the difference in durability is noticeable immediately. The high-carbon steel rear sprocket is heat-treated for maximum longevity, and the chrome moly countershaft sprocket provides superior strength. The gold color holds up well against dirt and debris without fading quickly. Installation was straightforward, and the chain length of 118 links fit perfectly. After several rides, everything is wearing evenly with no signs of premature stretching or sprocket wear. Whether you're replacing worn components or upgrading for better performance, this D.I.D kit delivers professional quality that stands up to hard motocross use. The value is excellent too - buying the chain and sprockets separately would cost significantly more. Definitely recommend for any KTM 250 SX rider wanting reliable, high-performance drive components that can handle serious track abuse!
