At the heart of the Moto Guzzi 850 Le Mans Mark II lies a potent 90-degree V-twin engine, its longitudinal configuration perfectly suited to the bike’s sleek, sport-oriented lines. Firing on a traditional OHV pushrod setup, each cylinder is fed by a pair of valves, carefully tuned to extract maximum power from its 850cc displacement.
This potent powerplant delivers a rich, throaty soundtrack that perfectly complements the bike’s aggressive styling, while its torquey, V-twin character ensures the Le Mans Mark II is as adept at carving up twisty mountain roads as it is at devouring long, sweeping highways.
As you delve into the saddle, the Guzzi’s engine comes alive, its smooth, linear power delivery making it a true delight to ride, as the bike’s agile handling and responsive steering invite you to push its limits even further.
