S&S Updates Twin Cam Big Bore Kit

Power Playah

Listen, Twin Cam, we know, Harley kicked you to the curb last year for something younger. Yes, it would be hard for anyone to take. You two crazy kids had a long relationship. But you gotta keep putting yourself out there. You think you’re the first V-twin Harley’s been with? H-D got rid of the Evo when you were young and look how that turned out. Two decades later, it’s still around. You just need a little reinvention and you’ll be fine.
What? No, I do not think a toupee is a good idea. What you need is something like S&S’s 100-/110-inch big bore kit. It’s just undergone a total redesign with new materials and is better than ever. They went back to the drawing board on it and created a unique formula of ductile iron that decreases wear characteristics and allows S&S to increase contact between liner and fins for better heat transfer.
ss cycle big bore kitInspired by their Pro Stock Drag Race engines, the updated big bore kit utilizes a Ductile Cast Iron liner wrapped in cast aluminum for optimum thermal conductivity and performance. 1999-2006 Twin Cam 88 engines roll up to 100ci, and 2007-17 Dyna/Softail and 2007-16 Touring become 110ci monsters. No machining necessary and install can be done with engine still in the bike. Kit works well with stock cylinder heads, or let S&S CNC port those heads for even more power. At 10.5:1 compression it makes for a very streetable and dependable engine that also responds well to performance cams. Available only within the USA at this time.

ABOUT S&S Cycle®

What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George J. Smith had to build his own parts to make his motorcycle faster. Now the company he founded manufactures the most pretigious line of "go fast" v-twin engine parts in the world. The company was started in the basement of his home in Blue Island IL in 1958, and moved to Viola, WI in 1969. In 2004 an additional facility was opened in La Crosse, WI.
