Swiss Street Tracker: Yamaha XS650 by Heritage and Sons

Yamaha XS650 Street Tracker

The Yamaha XS650 managed to combine the character and charisma of the British twins with something those bikes had rarely offered:  oil-tight reliability. What’s more, the XS was technically advanced for its day, boasting unit construction and a horizontally split crankcase.  Today, the XS650 remains one of the world’s most beloved vintage motorcycles, and it’s also a prime candidate for street tracker builds — after all, none other than King Kenny himself piloted an XS650-powered tracker in his day.

Enter Serge Lindemann, the behind custom garage Swiss Cruiser, who recently partnered with Dany Kunz of Switzerland’s Ace Cafe in Lucerne to found a new brand, Heritage and Sons, building and restoring vintage cars and motorcycles. This 1981 XS was one of their first projects, built as a street tracker with many handmade, one-off parts and a speed-block livery that harks back to King Kenny’s dirt track days.

We spoke with Noël Saugy, founder of, who’s responsible for the photos and sales of Serge’s bikes. Read on for more details on the build!
