Engine Specs

• The 95 Yamaha Big Bear 350 uses a single overhead cam engine, in which the 3.3 inch bore cylinders are all connected to one raised cam-shaft. These cylinders have a full stroke of approximately 2.5 inches --- the distance the pistons travel within the cylinders. The Big Bear has a four-stoke engine, which means fuel is inducted into the pistons on the first stroke, compressed on the second, ignited on the third and exhausted on the forth. The cylinders have a combined fuel capacity of 349cc. This is known as the displacement. A Mikuni BTM32SH carburetor delivers the fuel to the cylinders.
  
  

Drive Specs

• The 95 Big Bear is chain driven, which means it uses a chain to communicate the engine's torque to the back wheels, rather than a shaft or belt. It has five forward gears and one reverse. There is a double wishbone suspension at the front, which allows an engineer to fine tune the suspension and optimize the wheel motion, and a swingarm suspension at the back. The swingarm is equipped with a mono-shock, which means there is only one shock absorber connecting the rear swingarm to the chassis. This allows easier braking and handling.
