The MK136 is the latest in the line of complete replacement engines for your Harley-Davidson and S&S Cycle’s first for 2017 and later models.
The MK136 features the MK crankcase and its precision-machined oil scraper, patented dual-spray piston cooling jets and retention plate. It marries that to a set of 136-inch cylinders; forged pistons; and brand-new, high-flow cylinder heads featuring 0.605-inch lift springs, 0.30-inch longer valves, and oversized intake and exhaust valves, topped off with exclusive breather boxes. This massive displacement is sure to create an equally massive increase in horsepower, all while retaining stock engine height, so it will fit into your 2017 and newer touring frames.
To find more information and detailed specs, check out the S&S website or get them for yourself from your favorite local dealer today.
