well i thought the same. i drove an 00 cat 300 solid rear and it had single coil so the same travel (scaled) as leafs and they stunk on the mud. i ran great tires. upgraded to an 05 400 with ifs & irs and witht he same 25's i gat 3-5" more travel and could go through mud so mush easier. i could stop and go slow and didnt have to worry about it cause the wheel would travel. and when you go through mud you go slow... unless you have no fenders and like shooting mud. so in my opinion. leafs stink....
