For over 150HP applications. Gold colored chain. Comes with hollow rivet link for easy installation with industry standard tools. The X-ring is a very thin ''O-ring'' with an X shape which offers a drag reduction on rollers and side plates. Reduction in drag is such that efficiency is almost increased to the same level as a regular roller chain; with the longevity of a regular O-ring. This is the quality Tsubaki chain which combines superior strength and performance with the longevity well known to O-ring type chains. Average tensile strength 45.1 kN.- Gold colored link plates - Low friction ''X-ring'' seal ring- For over 150 HP bikes. Note: These chains come with a pin link (rivet style) master link. A clip style connecting link (506143 RQ1) must be ordered separately if desired.

The Delta QRN Self Lube chain is nickel plated. Rated up to at least 50 horsepower. This is the self lubrication version of the Tsubaki Gamma. Bushings are impregnated with special oil. When riding the lubricant is slowly released to minimize friction and reduce wear and maintenance. Comes standard with a clip style connecting link. Average tensile strength 31.4 kN.
