How a Racing-Inspired Upgrade Transforms Your Harley Experience
The Rider’s Dilemma: Power vs. Practicality
Every Harley Twin Cam owner between 2007-2017 faces the same crossroads – the craving for raw, drag-racing power versus the practical constraints of daily riding. Most settle for aftermarket exhausts or basic tuners, never truly satisfying that hunger for performance. Others risk expensive engine rebuilds that compromise reliability.
The S&S 110″ Sidewinder Big Bore Kit shatters this compromise, delivering Pro Stock Drag Race DNA in a bolt-on package that maintains street reliability. Inspired by championship-winning engines, this kit represents the pinnacle of big bore technology – the largest cylinder bore possible without machining your stock crankcase.
“I tried three different performance kits before the Sidewinder. Nothing comes close to the instant torque and that deep, angry growl. It’s like my bike finally woke up.” – Mike R., Sturgis 2022

From Stock to Shock: The Sidewinder Transformation
The Before
Your Twin Cam sits in the garage – reliable, familiar, but lacking that primal Harley Davidson thunder. You’ve added pipes, maybe a tuner, but it’s still not that bike – the one that turns heads before it’s even started.
The Breaking Point
That moment when a stock M8 or worse, some Japanese liter bike, pulls away from you at a light. Or when your riding buddy’s built shovelhead out-rumbles your fuel-injected modern machine. The internet is full of complicated, expensive solutions requiring engine removal and weeks of downtime.
The Sidewinder Solution
A weekend in the garage with basic tools transforms your bike. No special machining, no case splitting – just pure, bolt-on displacement increase. That first startup reveals a deeper, angrier exhaust note. The first ride delivers neck-snapping torque that feels stolen from a factory race team.
