238788 Wiseco Piston Kit 883 1200 XL 10 1 020

Transform your 883 Evolution Sportster into a 1200cc powerhouse with this Wiseco Big Bore piston kit. By boring out your original 883 cylinders, you can install these high-strength forged pistons to gain a substantial increase in torque and top-end power. Wiseco's forged construction offers superior durability compared to factory pistons, making this an ideal upgrade for riders who demand total reliability. The kit is designed for a straightforward installation that works with stock 1200 gaskets and does not require any complex crank re-balancing or cylinder head work. Sold as a pair, the kit comes complete with Hastings piston rings, wrist pins, and circlips. For owners of 2009 and later Sportsters, remember that you will need to use earlier 2004–2008 style cylinders as the late-model versions lack the wall thickness for boring.
