Standard 3.937" bore in 107CI models
These pistons are developed for the Milwaukee Eight 107CI (1,745cc) 4.375" stroke engines as introduced on the 2017 Touring models and give a 11:1 compression ratio. Like all Wiseco pistons these are forged, but feature ArmorX piston coating and ArmorFit skirt coating for reduced wear and auto-adjustment to the cylinder wall. Kits include 2 pistons, matching ring set, chrome wrist pins and piston pin locks. The 117 and 124CI pistons require resleeving or Big Bore cylinders.
