Product Details

The Wiseco K1314 is a complete forged piston kit designed for Yamaha FJ1100 and FJ1200 motorcycles. Wiseco's pistons are forged from high-silicon, low-expansion aluminum alloy, delivering superior strength, reduced reciprocating weight, improved heat transfer, and extended service life compared to cast alternatives.

Key Features:

  • Forged Aluminum Construction: High-silicon, low-expansion aluminum alloy provides exceptional durability and thermal efficiency under demanding conditions
  • Diamond-Turned CNC Finish: Precision CNC machining ensures a perfect bore fit with zero size variation, allowing confident installation in cast iron, chrome, Nikasil, and boron composite cylinder bores
  • Oversize Availability: Wiseco's oversize piston range extends the service life of worn cylinders; chrome, Nikasil, and boron composite cylinders can be re-sleeved to accept Wiseco oversize dimensions
  • Complete Kit: Includes forged piston(s), piston rings, wrist pin(s), and circlips — everything needed for a full piston replacement
  • OEM-Compatible Design: Engineered to meet or exceed original equipment specifications for reliable, long-lasting performance

The Wiseco K1314 piston kit is an ideal choice for engine rebuilds, bore restorations, or performance upgrades on the Yamaha FJ1100 and FJ1200. Wiseco's decades of motorsports engineering experience ensure this kit delivers the precision and reliability demanded by both competitive racers and recreational riders.

Great price and I like being able to pay through Amazon.

YES

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Loved being able to validate and pay via amazon!

Best price found quick shipping couldn't be easier will buy again.

Easy straightforward site setup.

great ! except i signed up for 20% discount and wasn't applied. that sucks.
