The appeal of a street tracker is simple: Basically a flat-track racer with lights, there is no more honest a motorcycle, just two wheels, an engine and barely enough essentials to squeak past a DMV inspection. Yamaha's venerable XS650 is a popular choice for street-tracker conversions – entirely fitting as the XS was a force on AMA dirt tracks during the 1970s, piloted by riders such as Kenny Roberts, Gene Romero, Don Castro and Chuck Palmgren.

Characterized by its fans as a "better Bonneville," the Yamaha 650cc motor unabashedly borrowed its layout from British parallel-twins, but improved upon the concept with oil-tight cases, electric starting and more. "Yamaha in its XS650 did upgrade the parallel-twin concept by adopting SOHC in place of pushrods and rockers, and by properly supporting the crankshaft with four main bearings – two of them between the cylinders," wrote Kevin Cameron in a Cycle World retrospective. "The more power Britain squeezed from its traditional twins, the more their flexy two-bearing 360-degree cranks became jump-ropes at peak rpm."
This Yamaha tracker is anchored by a stock XS650 roadster frame and running gear. A Trackmaster-replica gas tank and combination seat/tailsection impart the requisite look and appear to be from Omars Fiberglass, one of the prime suppliers of street-tracker parts. Shouldered alloy 19in. rims shod with blocky-tread tires also add to the transformation. Finally, a race-inspired exhaust system was fitted, its twin aluminum canisters mounted high on the left side.
