If you are looking for the toughest most hard wearing sprockets for your KTM, the search stops here!

Ironman rear sprockets are made of heat treated, nickel/chrome plated, chrome-molly steel that is 2.5 times stronger than stainless steel; 3 times stronger than 7075 aluminum.

A Ironman rear sprocket typically weighs 18 ounces versus 14 ounces for the same name-branded 7075 aluminum. That's a 4 ounce difference. Now compare that to an average of 30 to 40 ounces for a typical stainless steel sprocket.

What kind of life can you expect from an Ironman Sprocket?

The following is very typical:

Below (right) is a worn, but very usable rear Ironman sprocket. This sprocket is just at the .025" wear limit. This sprocket has been run for over 1000 hours on a 2002 and 2003 KTM 525. It required two bikes, five O-ring chains, and 31 Dunlop 695 rear tires to wear it out by an expert 220-pound desert/enduro racer who practices and/or races 10 hours per week.

This is typical wear in western desert and mountain conditions. Mud accelerates wear, but these sprockets will still outlast an aluminum Renthal in mud conditions, by 10 to 30 times. From experience, the 1000 hours in the below instance would have easily consumed 30 expensive aluminum sprockets. As most serious riders know, a powerful 450 eats sprockets at about the same rate as rear tires. 30 sprockets at £34 each is over £1000. How much can you save per year with Ironman sprockets? It's probably not far from your yearly rear tire budget.

The sprocket below on the left is a Sprocket Specialists aluminum with hard anodizing. It has 16 hours of sand racing/practice on it.

Please ensure you are tensioning your chain properly when running Ironman sprockets. If your chain is too tight even Ironman sprockets will wear quickly (and more worryingly you are probably doing a lot of damage to your gearbox output shaft bearing). In short, make sure there is play in your chain with your bike fully loaded with you sat on it. It is not sufficient to have 20mm of chain play with your bike unloaded on its side stand...
