Here’s a “very clean, all original” XL with less than 4,000 miles.
The XL600R featured a 589cc, 45 horsepower engine good for a top speed of about 100 miles per hour. This bike has recently rebuilt carbs with new jets, gaskets, and O-rings. The valves were adjusted and the only thing this bike could use is apparently a new battery (plus new tires, it still has the original ones).
Find this XL600R for sale in Los Gatos, California here on South Bay Riders for $2,400.
