Great size for motorcycle tyres. I was concerned the length was short for a lever but they were more than enough. Anyone who has leverage problems is picking up too many tires. Work in smaller increments. Some reviews mention kinks and I can't imagine those kinks. You are strong enough. Of course, as long as you're not trying to stretch too many hoops at once. Blade strength was very good. Thin enough to get in and out of, but not sharp or pointy. I've worked with large irons and it was very difficult because the tips were too thick to clip in and out. They went in and hooked the bead very well without taking over the whistle. You need 2 of these and I can see where even the 3rd would be handy although not required.
