I bought a pitbull for dynas at Sturgis last year, it works perfectly. Lifts the bike from it's stand position without straps and is solid. For me the choice was simple. I probably have close to $25,000 (or more) invested in this bike. I looked at the Sears yellow jack, almost bought one...the pitbull is a better choice. The extra cost of the pitpull -v- the headaches I've saved. Oh, and the dyna jack works on my Road King too.
