A nice little old ridgid frame minibike that I restored a few years ago that's crazy fast on top end. Too fast for small kids really. I completely went throught the older 3.5 hp Briggs and Stratton engine that came with the bike and modified it quite a bit. The motor came out awesome and It's one of the fastest minibikes that I've ever driven and own. This is a later version of the Wren kit by Bird Engineering, renamed and sold by Sears. The only noticable change over the years was the neck bracing.
