Worked well on a CRF 50 rear wheel. This will mark your rim, the power ribs on the bars themselves will also mark your rim. I used a 3/8 fuel hose with a slit down the middle on one side to protect the rim a bit. Tip: Lots of lube, I used very soapy water. Tire fails, inch by inch. Tip: Be prepared to work up a sweat.
