Press Release: We love power, raw unadulterated thumping, makes your heart skip a beat kind of power and that’s the very stuff S&S Cycle does best. This obsession with Hp and Torque is further proven out by their latest efforts for the Milwaukee Eight® powered Harley-Davidson® models. Their bolt in 124 Cubic Inch (that’s over 2000cc for you metric folks) Big Bore Kit is just this side of being a monster.
Taking the stock 107CI engine from a respectable 92Hp to a tire melting 125+Hp (and that’s with stock heads and throttle body!), we can’t wait to roll the throttle on one of these things! Maybe you’re a touring guy running two up and realize torque is what really matters? How about 135 ft lbs of pure twisting force (a 22% increase over stock!) that will transform your next, throttle onto the highway move into an authoritative launch. The S&S Big Bore kit is also available for the 114CI models, pushes them to a solid 128CI and both versions come in at 11.1 Compression.
