If you are one of the many proud owners of a Harley-Davidson’s Milwaukee Eight Engine, and you’ve been wanting something to boost your power, your wait is over. S&S Cycles just introduced its new 131 cubic inch stroker kit, suitable for all your M8 power-enhancing needs. Just in time for Xmas as a gift for yourself or for that special someone in your life that has an M8 engine, plus we here at AMERiders will give you a few more gift ideas as well.
You know that saying “there’s no replacement for displacement?” It applies to all types of internal combustion engines, fitted on both cars or motorcycles, and has been the driving force behind many stunning machines over the years. Generally, these engines come in three displacement options, namely 107, 114, and 117 ci.

In the motorcycle world, this just happens to be Harley’s Milwaukee Eight engine 131“the biggest, most powerful street-compliant engine Harley-Davidson has ever created,” but this one is offered as a crate solution. is one of the most famous powerplants. Part of the big twin family that has been around for eight decades, it was introduced in 2016 with a total of eight valves – four for each cylinder – hence the name.
Those looking to get more cubic inches and more power have several solutions at their disposal. The latest comes from S&S and is designed for Milwaukee Eights fitted on bikes from 2017 to the present day.
As you’d expect, the displacement increase also amps up both horsepower and torque. How much difference does it make? What’s in the kit? New design forged pistons are paired up with S&S’s 4.25-inch cylinders, along with piston rings and .045-inch multi-layered steel head gaskets. You also get a 131 cam cover badge if you want to show your work—or you can leave it off to keep it stealth. “We build our big bore kits and cranks to much tighter tolerances and with higher quality materials than the factory parts,” project manager Grant Hilligass said.
Comprising upgrades like a new-design forged piston and 4.25-inch cylinders, the kit can take engines all the way to 131 ci (2.1 liters), but only when paired with the company’s stroker crank – we’re told the upgrade works with stock crankcases as well. According to S&S, the stock engine height remains after the kit is fitted, and so do the original serial numbers.
There are three variants of the kit available, namely Wrinkle Black with highlighted fins, Wrinkle Black with non-highlighted fins, and Black Granite with highlighted fins.
Regardless of the version, the price is $1,299.95, but that increases to $1,529.95 when opting for the stroker crank as well. Still, that should be peanuts given what the hardware offers, according to S&S product manager Grant Hilligass.
“We build our big bore kits and cranks to much tighter tolerances and with higher quality materials than the factory parts,” he states.
