This site is dedicated to Performance  2 Stroke Motorcycles.  The links I have provided are some of the very best for obtaining info on certain aspects of 2 Stroke machines both road and racing.

This is my 1989 RGV  "J" model with Stage 1 kit.  I still have to finish the paint on the fairing and tidy up a few things.

Yeah I'm Surf'n and continually updating....
Road testing the RZ 250.....we had just stopped to do a quick repair....the right hand can on the RZ 250  had lost 2 bolts and was only held on by 1 bolt, just as well i had a couple of spare ones.  In a few minutes we were on our way.  It was a great ride, my brothers RZ went very well.  The RZ 250 is here to stay, it will not be sold.
The following images show the RZ 500 engine in various stages of assembly
