What is most important when building a custom motorcycle?

The key to building a custom motorcycle is to decide on how you will be using it (around town, cross-country trips, weekend camping, racing) and how you want it to look. Having a goal will make it easier to decide which parts you need for your build. Check our How to Build a Bobber article for more info on a custom build.

How to make my motorcycle faster?

Horsepower will make your motorcycle faster. This is often achieved by using a free-flowing air filter and exhaust system that is properly tuned. Other methods include increasing the engine displacement (with a big bore kit) and other engine modifications (custom camshafts, cylinder head work, etc).

What changes should I do to make my motorcycle more comfortable?

Setting up your motorcycle for riding comfort is time well spent. Pay particular attention to the style of seat, footpeg location and handlebars. Handlebar height (rise) and pullback (how far the handlebars come back toward the rider) are very important for comfort as well as handling of your motorcycle. A high quality seat is worth every penny on that long road trip!

Looking to enhance your motorcycle's aesthetics or boost its performance? At Lowbrow Customs, we've got you covered no matter your riding style. Whether you're mending a part or improving your motorbike's current configuration, our online store offers hundreds of universal or bespoke custom motorcycle parts and accessories that can revitalize your Harley, BSA, or Triumph.

WHAT MAKES CUSTOM MOTORCYCLE PARTS BETTER THAN COMPANY-MADE?

Motorcycles equipped with custom parts, such as Harley Davidson aftermarket components, can present distinct advantages over standard company-made parts. These specialized aftermarket options are tailored specifically for Harley, BSA, or Classic Triumph motorcycles, offering a suite of benefits that many riders find attractive.

Custom parts are often designed to enhance the performance of a motorcycle.
Riders can choose parts made from premium materials such as carbon fiber, titanium, or high-grade alloys, which can be lighter, stronger, or more aesthetically appealing than stock components.
Universal custom motorcycle parts often allow riders to personalize the appearance of their motorcycles, creating a distinctive look that reflects their individual style and preferences.
Depending on the brand and specific component, aftermarket motorcycle parts can sometimes be more cost-effective while still providing comparable or superior performance and quality.
Finding specific OEM parts for BSA, Harley Davidson Big Twin motorcycles or Vintage Triumph can sometimes be challenging, especially for older or less common models.

At Lowbrow Customs, our experienced team of motorcycle builders ensures you find the perfect custom part for a smooth ride and a unique look. With a comprehensive catalog of quality brands like Colony, Cycle Standard, British Standard and Biltwell, clear fitment data, and helpful reviews, we're your go-to online source for motorcycle parts.

Benefit from our hassle-free 90-day return policy and exceptional customer service, available via chat, phone, or email, to make your shopping experience unparalleled. Enjoy the ride with confidence!
