The Alpha type chain by Tsubaki is smooth running with a minimum of power loss combined with the benefits of X-sealed inside lubrication that provides a longer chain lifespan. A great chain for hi-torque, hi-horsepower performance bikes. Available as Alpha XRS in plain steel and RQ2 with gold coloured outer links. Same chain, same quality.

The Sigma XRG 530 is the highest strength chain available from Tsubaki. While the steel coloured version keeps this name, the version with gold coloured outer plates changed it to RQ1. Quality and strength of course stay identic. The X-seals keep the factory-applied lube inside the bushings and minimize friction caused power loss. The choice for top horsepower bikes.

The Delta QRN 530 is a non-sealed high quality roller chain. The bushings between roller and rivet are made from sintered metal and oil impregnated (HSL), which in turn results in longer service spans. The side plates are nickel-plated for corrosion protection and good looks.
