The Unlimited Racing 855190 Pu 420 O-Ring Chain with 110 links is a premium quality motorcycle chain designed for high-performance applications. This chain is manufactured using C maps roller technology, ensuring optimal roller contact with the sprocket, resulting in improved power transmission and better efficiency. With a pitch size of 110 links per inch, it is ideal for use in various motorcycle models and applications requiring an 110 series chain.
The Pu 420 O-Ring Chain is made with high tensile strength materials for enhanced durability. Its outer plate is constructed with galvanized, nickel-plated rollers, while the inner plate is made of chrome-plated, heat-treated steel for improved wear resistance. The 1/2 x 5/16" cross-section links ensure a secure fit and proper engagement with the sprocket, delivering superior strength and stability.
One of the notable features of this Unlimited Racing chain is the use of O-rings. These o-rings help reduce lubrication loss, keeping the chain lubricated for longer periods and reducing the need for frequent oiling. They also serve to prevent dirt, dust, and debris from entering the roller gaps, ensuring cleaner, smoother operation for enhanced engine performance.
This chain has a rolling contact seal design, which features precision machined o-ring grooves to ensure proper sealing and maximized contact area between the o-rings and chain rollers. The proven sealing technology ensures an effective barrier against contaminants, while also facilitating easy installation and removal of the chain without damaging the o-rings.
