DID is the worlds best selling chain with a reputation for making superior race chain.

Valentino Rossi and Ricky Carmichael are two of the best riders currently competing at the highest level.

MotoGP bikes produce over 200 hp. A broken chain means a DNF to Rossi.

MX competition punishes chains in a tough harsh environment. A chain that stretches and de-rails puts Carmichael out of the race.  Naturally they want the best chain. They both put their trust in DID.

Closer to home many Australian championships are won with drive from DID.

Maxxis 2004 Australian MX Championship (Mr. Motocross) - Pro Open Darryll King - Pro Lite Cody Cooper.

Australian 2004 Superbike AND Supersport Champion Adam Fergusson. These guys know DID is best Motorcycle chain.

But what about 4-wheelers ?
Now there is DID 520ATV “X” Ring race chain for High Performance Sports Quads.

DID 520ATV chain is built to close tolerances using

• DID’s patented tough “Dai Hard” chromium carbide hardened pins give longest wear with highest impact strength
• Pins are quad-riveted for maximum side plate security
• Machined solid bushes
• Fatigue-fortified 2.2 mm high tensile alloy steel side plates.
• DID’s patented “X” rings create less friction than other manufacturers seals because at no point are they “squashed” as occurs with “O”Rings or other types of lipped-seals. DID “X” rings use torsional tension and not compression to seal the pin-bush pivot. That means a smaller loss of horse power to transmit the drive to the rear wheels.

With a tensile strength of 3,380 kgs and a wear-life factor 23.5 times that of a standard chain 520ATV handles high performance riding and gives superior service life.
