The Wiseco Black Edition 103 CID 10.5:1 Piston Kit (part number K2792) is a replacement piston set built for V-twin engine builds that call for a 103 cubic inch displacement and a 10.5:1 compression ratio. It is designed for riders refreshing an older engine or putting together a new performance build who want more power output from the same displacement.
The kit's 10.5:1 compression ratio is positioned as a practical middle ground for many performance builds, giving a noticeable power increase without being overly aggressive for street use. The ring package uses a premium compression ring for a strong seal against combustion gases, a Napier second ring with taper face and underhook for oil control, and a 3mm oil ring with higher tension for lubrication management.
Wear and friction are addressed with two coatings. Armor X is applied to the piston crown to reduce wear and extend piston life, while ArmorGlide on the skirt minimizes friction and improves scuff resistance. Together these features are aimed at helping the engine run stronger for longer under high-performance demands. The kit weighs 2.4 lbs.
For off-road / closed-course race use only.
