The weakest links in a high performance engine are the connecting rods and wrist pins.  Several companies have addressed the rod issue.

APE manufactures racing's strongest wrist pins. Machined from special tool steel bar stock, and utilizing a propriatary heat treatment.

APE is the only motorcycle aftermarket parts supplier that actually manufactures tool steel wrist pins in our own facility. We control the material used, the manufacturing process, the end quality.  

That's why APE tool steel wrist pins are used in the world's most powerful racing engines, from Larry "Spiderman" McBride's 248 mph top fueler, to the world's first 6.30 sec high gear only nitro Harley. Other APE performance milestones include the first 200, 210, 220, 230 and 240mph quarter mile runs. There has never been a record of a broken APE pin. Today's modified sport bikes are pushing 300 to 700 hp and this demands super strong components.

APE manufactures pins for all popular Wiseco, JE and CP pistons. These aftermarket pistons do not come with tool steel pins. They need to be ordered separately from APE.

We also make a replacement tool steel pin for the 08 Hayabusa. The factory reduced the oem pin diameter from 20 to 18 mm to accommodate the stroke increase. No need to worry about the smaller pin when building turbo / nitrous big power motors.
