Big Wheel: Yamaha XS650 Bobber by A&J Cycles

Yamaha XS650 Bobber

A metric bobber recalling the Big Wheel trikes of yesteryear…

The Yamaha XS650 remains one of the most versatile vintage motorcycles in the hands of custom builders. We regularly see the British-inspired Japanese twin transformed into a street tracker, scrambler, cafe racer, or some combination thereof. What’s more, the bike is also used as a platform for hard-tailed creations like this ’81 XS650 bobber, a personal project from Rob Salle of A&J Cycles — the New York workshop that created the Triumph Scrambler 1200 “XEcutioner” we featured last fall. Founded more than 20 years ago, the shop focused on turbocharged Hondas in the late 90s before shifting exclusively to motorcycles in the last decade.

Rob’s wife gave him this project as a wedding present, running but in need of a lot of work. Rob’s vision was clear:

“Just wanted to make a cool, clean bobber.”

One of the signature pieces of the build is the 23-inch front wheel from a 1980s Honda XL500, which gives the bike its nickname, “Big Wheel” — just like the low-riding tricycles of our youth. About the only tire available for that rare wheel size is the Bridgestone TrailWing, which gives the bike a knobby tire / dirt chopper look. With no front brake, Rob did a rear disc brake conversion with a Cognito Moto hub for better stopping power. He rewired the bike using a Black Box lighting control module from our friends at Purpose Built Moto and went with a Pamco electronic ignition. The electronics try and frame paint are by Dave of @Slagkustom, while the gorgeous paintwork is from Ronnie Melendez of Weights and Paints. While this isn’t our standard fare on BikeBound, we can’t help but love the lines and detail of this streamlined, squeaky-clean build.

Below, we get the full details on the build along with some gorgeous shots from Dave Ngo (@davengo) of MotoFellas NYC.

    Too much space under the seat !

  2. Any travel in the front forks before the internals hit a stop? Hate to see that tire hit the lower yoke.

  3. What frame is this?
