Motorcycle

A motorcycle is a single-track, engine-powered, two-wheeled motor vehicle. Its ability to negotiate difficult terrain and provide quick movement of personnel has made it a valuable tool for military use.

Usage
In 1964, EVA rode a Russian-made replica of a German BMW R75 motorcycle (sans the sidecar). It was extraordinarily powerful and she was highly competant with it. According to rumors, the Soviets confiscated an entire production facility for the BMW R75 (including all the completed models) after winning World War II, which explained their presence in the Soviet Union. Later, EVA had it fitted with a sidecar, allowing Naked Snake to act as a gunner as the two fled Groznyj Grad, while being chased by the Shagohod (piloted by Volgin) and GRU soldiers riding their own German BMW R75 motorcycles (with sidecars) and Ocelot with his own German BMW R75 motorcycle as well. After the Shagohod's destruction, Snake and EVA were again pursued by mounted soldiers. After succesfully escaping, Snake and EVA's motorcycle was revealed to be leaking fuel, as the tank had been hit by gunshot during the chase. The distraction caused their motorcycle to crash, with Snake receiving minor injuries, and EVA becoming impaled on a nearby tree branch, though her wounds were not fatal.

In 1970, Naked Snake (Big Boss) recounts several times his and EVA's motorcycle ride back in 1964 while being tortured by Cunningham and Gene.

Peace Walker Incident
Main Article

In 1974, Big Boss (Naked Snake) used a motorcycle (likely a Triumph Bonneville, a known motorcycle made during the 1970s as it featured a twin pea-shooter exhaust, fuel tank decorations, and parallel twin engineto) arrive at Barranquilla Coast, Colombia to oversee and train with the Militaires Sans Frontieres.

In 2014, Big Mama and Old Snake rode on a Triumph Bonneville, while some of the Paradise Lost members used black Triumph Speed Triple 1050s during Liquid Ocelot's assault in Eastern Europe. Big Mama's Bonneville was a post-2001 remake produced in Hinckley, with various add-ons from Triumphs "Sixty-8" line of accessories. After evading the Raven Sword PMC, Snake and Big Mama's motorcycle crashed outside a building, with Snake disoriented and Big Mama impaled by a steel rod.
