Chain:
Finding an X-Ring chain that fits the 2019+ Honda CRF450L / CRF450RL can be a little tricky. Even if you order the correct 520 size, many X-Ring chains will be a bit too wide and can rub on the engine case behind the front sprocket. We contacted D.I.D about this, and they recommended their 520 ERVT Racing Chain. These chains are slightly narrower than comparable X-Ring chains, and feature their low-friction D.I.D X-Ring for greater performance and longer wear. We use these chains on several of our project bikes, in addition to our two CRF450RL's.
Rear Sprocket:
For a rear sprocket, we're big fans of the Supersprox Stealth line of sprockets. The design and construction of these sprockets give you longer sprocket/chain life, without compromising weight. An all aluminum center section of the sprocket is 70% lighter than steel, while the outer part of the sprocket is made of steel and the teeth will last 4 times longer than aluminum. The Red anodized aluminum center with black steel outer section looks very trick on the CRF models!
Front Sprocket:
Finally, for a front sprocket we like the ones from Renthal. Their front sprockets are precision CNC-machined to extremely tight tolerances to give the ultimate combination of strength, light weight and durability.
