The Yamaha SR250 is a single cylinder, air cooled motorcycle produced from 1980 to 1982 in the United States. Similar to its older brother the SR500, the SR250 is very much a commuter bike. With a top speed of only 72 miles per hour, and only 249cc of displacement, it's not a canyon carver by any means, but at 60+ miles per gallon, and with aircooled reliability, it's an excellent commuter bike.

ENGINE TUNE-UP SPECIFICATION AND ADJUSTMENTS: AT NORMAL OPERATING TEMPERATURE, PUT VEHICLE IN THE UPRIGHT POSITION, TRANSMISSION IN NEUTRAL, AND WARM UP ENGINE.
