Things that make me go ohh #13: Kawasaki AR50.
If I had to use one word to sum up the Kawasaki AR50 it would be 'spindly'.
There are knitting needles out there that are fatter than those forks. The whole bike is dinky but it packed a punch, the best bit was all of the parts from the AR80 engine could be grafted on by any teenager who had access to a socket set. There was also the 93cc big bore option, that coupled with the AR80 gearbox made for a really nifty fifty.
