I spent the weekend ripping around in this fantastic machine. R1 powered home built.
There wasn't a sand dune steep enough in Glamis that this thing couldn't wail up.
It does not have reverse but that was never an issue . It is light and handles phenomenally well.
It is a dead stock, fuel injected R1 out of a wreck and is a perfect motor for this application.
Second and third gear are used for most attack mode situations and if you need more power, punch it and the thing just hooks up and rockets.
