Athena Hyper Race Cylinder Yamaha Zuma 2002-2011 70cc cylinder kit 12mm wrist pin

Athena Hyper Race 70cc cylinder kit Yamaha Zuma 2002-2011. 

This is the Athena HPR Racing 70cc cylinder kit. Like the Athena Sport 70cc cylinder kit the porting and quality is excellent making them very durable. The Hyper Racing line features a extreme port lay out and flat top piston for added power.

These kits are higher revving than the sport cylinders and will need a suitable exhaust like the Polini 4 Race, Yasuni C16, Stage6 R1200 to name a few.

Recommended carburetor 19-21mm

Minarelli Horizontal

12mm wrist pin 

Athena part number 081000/1
