Used Mini Rok from Allison, new top have 3 days on it, very fast and good engine. $600
Other New Mini Rok from Europe, done by same builders from Parolin and Baby race and other teams. Very fast engine, all new top and bottom, have zero hours, new carb, new ignition, new coil, and lots of spares, paid 1200eur to rebuild and update. Prepared myself for rok cup but we not doing it, and looking to trade to swift. $900 comes with brand new pipe and 2 used pipes. Air box, engine mount, harness.
$1400 for both.
So nothing wrong with the motors just not doing any rok races.
