stage6 STREETRACE air cooled cast iron minarelli vertical 70cc scooter kit. supposedly can produce between 8 and 11 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 5 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. The cylinder comes with a high quality 2-ring piston and a HC
cylinder head. Maintenance and adjustment are easy, and of course you
will find all necessary spare parts in our shop.
Performance characteristics are similar to the Sport Pro - powerful
take-offs and acceleration, with an engine speed of approx. 10,000 rpm,
with up to 8 - 11 hp, which is 1 - 3 hp more than comparable cylinders.
Of course, the cylinder can only unleash its full potential when
combined with the matching components, you will find some
recommendations below.

10mm wrist pin
