What good is Go if you don’t have Whoa? The brake system is one of the most important group of components on a motorcycle for obvious reasons. Twin Power takes American V-Twin brakes seriously. We offer the finest precision ground Spanish made stainless steel rotors in both floating and solid mounted styles in several designs. Our brake pads are available in X-Stop Sintered and Organic compounds for sure stopping. Finish off your braking system our D.O.T. brake line kits, universal series lines, and wide array of banjo bolts, junctions, and adaptor fittings. Everything you need to plumb up any braking system from stock to full on custom.




The American V-Twin Drivetrain is a lot more complex than it initially appears. Everything between the engine and the rear wheel makes up this critical group of components. This includes the primary group comprised of: the primary housing, compensating sprocket or compensator eliminator, primary chain, primary chain adjuster clutch shell, clutch hub, and clutch pack. Power is transferred into the transmission next and finally the rear wheel via pulleys and belts or sprockets and chains. All of these happenings are aided by the clutch release system including the throw out bearing, pushrod, ramp or hydraulic release. Twin Power will keep ya’ going down the road, not on the side of it!

Proper fuel and air control is essential to a crisp running American V-Twin. When it comes to carburetors, we offer a wide array of tuning components including jets, recalibration kits, needles, and more.

Twin Power is dedicated to using the best materials for all of its products, including its line of lubricants designed specifically for American V-Twin engines, all of which are made in the USA. Twin Power oil is not just another repackaged oil, but specifically developed for its application. An oil for an Air Cooled American V-Twin has unique needs. The oil must have extreme heat resistance, resistance to extreme pressure and resistance to heat cycles. This requires a completely different base stock than, say, a liquid-cooled metric engine. The additive package chosen is also unique, including anti-friction additives, extreme pressure additives, anti-shear additives, viscosity improvers and dispersants and inhibitors to control combustion by-products. Hours of laboratory testing are required to validate the finished product to make sure it’s better than the competition. The same parameters are used in the development of all our lubricants, including transmission oil, primary oil and suspension fluids.


Twin Power oil filters are specifically designed for your American V-Twin and packed with features at a great price. Optional built in nut allows easy wrench removal. Twin Cam filters utilize a 10 micron material and an anti-drain valve, while earlier models use a 20 micron material without anti drain valve. They are also available with magnet and in black or chrome.


Let’s face it; there’s nothing sexy about inner tubes, and you never give them a second thought till one lets you down. Twin Power inner tubes are molded from heavy duty extra thick natural rubber with heavy duty valve stems. They are reinforced and available in a wide range of sizes with either metal or rubber stems in straight or offset configurations. You wouldn’t buy cheap condoms, why skimp on your inner tubes? It’s just not worth the risk!
