Ironman Rear Sprocket RM 250 (86-08) DR/DRZ 350,400 (90-08) , RMX 250 (89-01)



  • High quality heat-treated special chrome-moly steel is 2.5 times stronger than steel and 3 times stronger than 7075 alloy.
  • 250,000 psi material in a protective nickel finish.
  • "Closed Truss" design on rear sprockets more evenly distributes stresses in the rare event of a missing sprocket bolt. This decreases stress levels everywhere, allowing for an overall decrease in weight. Weighs just a few ounces more than your typical alloy sprocket.
  • Countershaft (front) sprockets are made of shock-resistant die steel, much stronger than "case hardened" steel.
  • Ironman sprockets come with a 1-Year manufacturer guarantee against wear! That's right! We're so confident your Ironman Sprocket will outlast anything you've ridden before, Ironman guarantees it against wear for a full year!
