Collection: Husqvarna 401

The Husqvarna Svartpilen/Vitpilen 401 is a lightweight, agile machine that combines modern street performance with a playful, adventurous attitude. Its single-cylinder engine delivers punchy performance, while the minimalist chassis and upright ergonomics make it ideal for city streets, twisty backroads, and weekend explorations. At Kelpi Custom Moto, we provide upgrades that allow 401 owners to personalise their bikes, improving style, comfort, and everyday usability.

One of the most popular upgrades for the Svartpilen and Vitpilen 401s is a high-quality slip-on exhaust. Lighter than the stock system, a slip-on enhances throttle response and delivers a sharper, more defined exhaust note. It gives the bike a sportier sound and character while retaining reliability and road legality, making it a practical yet performance-focused modification.

Hand-crafted custom seat trims are another way to elevate the 401. Using premium materials and precision stitching, these seats improve long-distance comfort while adding a distinctive, bespoke look. The upgraded trim complements the Husqvarna’s minimalist styling and allows riders to create a bike that feels personal and well-finished.

Aftermarket handlebars and grips help refine the riding position and improve overall control. Adjusting the sweep, height, or shape of the handlebars allows riders to tailor ergonomics to their preferences, whether they prefer a slightly upright stance for relaxed city riding or a more aggressive position for spirited cornering. Premium grips provide better tactile feedback and comfort, enhancing the connection between rider and machine.

Bar-end mirrors are an ideal finishing touch for the Husqvarna 401. Their sleek, minimal design improves rear visibility while reducing vibration and maintaining the bike’s clean, modern aesthetic. They help the 401 feel more complete without detracting from its lightweight, aggressive character.

LED lighting upgrades, particularly indicators, are another simple yet effective way to modernise the 401. Brighter, crisper LEDs increase visibility for other road users and add a subtle contemporary edge to the bike’s look, complementing the compact, minimal styling that makes the Husqvarna 401 so distinctive.

All Kelpi Custom Moto components are E-marked and road-legal in most countries, giving riders confidence when upgrading their bikes. For country-specific regulations, our FAQs page provides guidance to ensure compliance before purchase.

Customising a Husqvarna 401 is about enhancing its playful character while making it feel truly your own. Thoughtful upgrades like a slip-on exhaust, hand-crafted seat trims, LED indicators, refined handlebars and grips, and bar-end mirrors improve performance, comfort, and style. Kelpi parts are designed for riders who value intelligent, high-quality modifications that elevate the 401 without compromising its lightweight, agile nature.
