Product Details

The Wiseco K1748 is a forged piston kit designed for Harley-Davidson 1200cc Sportster and Buell XB12 engines, delivering a 10.5:1 compression ratio for improved throttle response and performance. Each piston is precision-manufactured to exacting tolerances, making this kit a reliable upgrade for both street riders and performance enthusiasts.

Key Features:

  • High-Silicon, Low-Expansion Forged Aluminum — Wiseco's proprietary alloy provides superior strength over cast pistons while reducing overall weight and improving heat transfer for longer engine life.
  • Diamond-Turned CNC Finish — Computer-controlled turning centers ensure a perfect surface finish with zero size variation, allowing confident installation in cast iron, chrome, Nikasil, and boron composite cylinder bores.
  • 10.5:1 Compression Ratio — Raises compression over stock for enhanced power output and improved combustion efficiency on 1200cc Sportster and Buell XB12 platforms.
  • Oversize Availability — Wiseco's wide range of oversized pistons extends the service life of worn cylinders. Compatible with resleeved chrome, Nikasil, and boron composite cylinders.
  • OEM Part Number: K1748

Wiseco's state-of-the-art manufacturing facility has made them a trusted name among performance builders and recreational riders alike. The K1748 piston kit upholds that legacy with precision engineering built specifically for Harley-Davidson and Buell V-Twin applications.
