Plymouth, Wisconsin based Revolution Performance unveiled is long awaited 124” M-8 bolt-on Big Bore Kit at the recent Drag Specialties Dealer Expo at Indianapolis.
Taking the stock 107” 2017-208 M-8 (2018 Softails as well as 17/18 Tourers) out to 124”, the company say the kit makes +25 percent more power and runs 30 to 40 degrees F cooler with no other modifications because the heat is dissipated much better than with the stock cast iron cylinders.
“True bolt-on power and reliability,” says Revolution’s product specialist Andrew Dellenbach.
The kit comes complete with new 4.250” all aluminum plated bore cylinders, new 4.250” flat-top forged pistons and new Cometic head/base gasket kit (0.030” head, 0.020” base).
The kit fits 2017-2018 107” Road King and Street Glide Specials; Road Glide Special and Ultra; Electra Glide; Ultra Classic; Ultra Limited (Low); Freewheeler and Tri-Glide Ultra, plus the 2018 Street Bob, Low Rider, Softail Slim, Fat Bob, Deluxe, Fat Boy, Heritage Classic and Breakout.
