On my 2 GasGas 300?s, I got 2961 miles and 3250 miles out of Ironman front sprockets trail riding in Oregon and Washington west of the Cascades. Admittedly, they were quite hooked when I replaced them. I should have replaced them earlier.
In comparison I got 648 & 879 miles out of the stock sprockets and 681 miles out of a Sprocket Specialists sprocket by the time they were significantly hooked.
Overall, I average 13-14 MPH riding technical woods trails with my sons and friends.
