Wiseco EV Sportster® 3-13/16” Bore Pistons

Forged pistons specifically designed for use with XL & Buell 883/1200 engines converting to 3-13/16” bore. 15-degree dome configuration designed to match our CNC ’04-up XL or ’91-’03 Thunderstorm® heads with fully machined combustion chambers. Lightweight, slipper design weighs similarly to a stock 3-1/2” piston, eliminating the need for re-balancing work in 88” conversions. Three different dome configurations (no dish, shallow dish and deep dish) allow the builder to match the best piston for the application.
