The wait is over for American enthusiasts, as the 850 Le Mans Mark III returns to the US market, boasting a smaller, more intense engine and a multitude of changes made to European versions. This longitudinally-mounted, 90° V-twin powerhouse, with its OHV pushrod and 2 valves per cylinder, delivers a unique riding experience that’s anything but conventional. The 850 Le Mans Mark III is not for those who crave the typical Japanese sport-bike formula – its switches, seating position, and handling are refreshingly idiosyncratic. This is a motorcycle that will delight those who thrive on the unique, offering a quality of power that’s both distinctive and exhilarating. The 850 Le Mans Mark III is back, and it’s ready to shake up the US sport-bike landscape.
