The gold finish provides a polished look to the drivetrain while the aluminum sprocket reduces unsprung mass, which is beneficial on rough terrain and during jumps. This kit is suitable for high-displacement motocross bikes — notably the KTM 450 EXC-F (including Six Days) — and is designed for standard installation with a 520 pitch. It is advisable to check the number of links and the sprocket/sprocket ratio during installation to ensure precise tension adjustment and uniform wear.
