Whether it's a frame for a Norton Commando, a gas tank for a Triumph Bonneville, or a fairing for a BMW R90s, the right part can make all the difference when restoring a vintage British or European motorcycle. When it comes to British bikes, Lucas is the proverbial fifth Beatle, making headlamps, tail lights, and electrical parts for Nortons, Triumphs, BSAs, and Royal Enfields, often to the chagrin of the owners of those bikes. Thanks to more-predictable German engineering, weekend BMW mechanics have it a bit easier, while those who like to ride Ducatis and Moto Guzzis are obviously focused on style.
