this is an air cooled cast iron minarelli horizontal 70cc scooter kit. supposedly can produce between 10 and 13 bhp. pretty nice for an ac kit if yah ask me.
A powerful cast iron cylinder for everyday riding. The Streetrace
is a lower-priced version the popular Sport Pro aluminium cylinder.
Reliable and powerful, this is the perfect cylinder kit for everyday
use, with great torque and increased top speed for maximum riding
pleasure.
Transfer port layout with 6 ports plus 1 simple exhaust
port is basically identical to the more powerful 70cc Sport Pro kit, it
was slightly modified to meet the thermal requirements of a cast iron
cylinder.
47.6mm diameter bore
10mm wrist pin
includes everything in the photos.
