The Stage6 Sport Pro 70cc aluminium cylinder has always been an affordable yet very high (European made) quality cylinder kit which has long been popular with in scooter tuning.
Now Stage6, with their new Sport Pro MKII, are taking it one step further!
This MKII version of the Sport Pro is a completely new design and includes new transfer ports design which gives a 2 hp increase over the earlier kits.
With the right components this kit can make 15-17 hp straight out of the box.

Cosmetically this kit resembles the pentagonal shape of the R/T cylinders and the head is a one-piece construction with cast scavenging passages for better heat transfer.
The piston used is a replica of the R/T version, with domed crown and 0.8mm ring to increase performance and improve thermal stability.

Note: The temperature sensor used should not be longer than 18mm (incl. thread)- check dimensions!

Use with BR9ES spark plug.
