DID 520 DZ2 chain is a high performance racing chain designed specifically with local racers and off-road champions in mind. Designed to meet the demand of even the most gruelling tracks with SDH technology. The use of DID's patented SDH technology results in a longer lasting chain.  

Our front sprockets are CNC machined from high tensile steel and case hardened to resist wear. Some sprockets feature lightening holes on selected models, but only when durability will not be affected.

Renthal Ultralight Chain wheels are chosen by more Factory Motocross and Supercross teams than any other brand on the market. The rear chain wheels are CNC machined to offer the greatest concentricity and optimum tooth profile for increased life and durability. Through the CNC machining process, Renthal are able to create and extremely lightweight rear chain wheel which reduces revolving unsprung weight and increases the power transfer to the rear wheel.

Please note: The images provided are an example of what you will receive. The sprockets may differ slightly (depending on what model of bike you have) and the packaging may vary. A basic set of tools will be required and you may need to shorten the chain to the appropriate size.
