Tsubaki 525 XRG Sigma X-ring chain, 108 links

The XRG is a gold color chain. The X-ring is a very thin 'o-ring' with an X shape which offers a drag reduction on rollers and side plates. The 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 and fit to handle at least 200 horsepower. 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. Note: These chains come with a pin link (rivet style) master link. A clip style connecting link must be ordered separately if desired. Fits: > Aprilia: 00-03 1000 RSV Mille R; 03-05 1000 RSV Mille Tuono
