Introducing the next generation of Proven Performance for your 2017 & newer H-D Touring Models, the MK136 Engine.

This is the newest version of the complete crate engines S&S is known for, ready to install in your M8 Touring bike. We took our MK-Series Crankcases, married them to the 136in. cylinders and flywheels, and then fit High-flow cylinder heads with +1mm Valves and .605in. springs.

This is everything you need to have the largest, most powerful, and most reliable crate engine
