Description

The Wiseco K1641 Piston Kit delivers the reliability and precision your Evolution Big Twin demands, whether you're rebuilding a tired top-end or overboring for increased displacement. High-silicon aluminum construction provides the thermal stability and strength needed for consistent performance across demanding riding conditions.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
