I use them in emergencies because they are very light and allow me to carry two tools less. I used them to change tires on my WR250R. The front passed without incident. The rear tire needed more torque to get the tire off the rim than I was comfortable applying with the short lever. BUT, I had no problem getting the bead off the tire and that's all you have to do to replace the tube anyway. So for emergency roadside camera repairs, these levers are perfect. If you really need to take the tire off the wheel I would use a longer steel lever. Since I believe the purpose of this item is to fix the trail, I didn't scold her for it. They are very light, strong enough and packed very well. Caution: Aluminum scratches easily. I keep them wrapped in a microfiber cloth to prevent other tools from scratching the sharp edges.
