Replacement OEM Yamaha parts.
The Stage6 Sport Pro 70cc aluminium cylinder is a good and affordable cylinder that has been popular with many tuners - and now Stage6, with their new Sport Pro MKII, are taking it one step further. A completely new design incl. new transfer ports cater for 2 hp more, which with the right components results in 14-17 hp right out of the box. The appearance is based on the pentagonal shape of the R/T cylinders. 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. We are sure that this cylinder will set new standards in the tuning scene.
