A Diversity Antenna system has two, or more, antenna which are mounted on a vehicle. The system will select which antenna to take the radio or other device, signal (AM, FM, WiFi, satellite, microwaves, mobile phones), from depending on which one is receiving the clearest signal – also known as best Signal to Noise Ration (SNR). Users should experience less ... Read More »

Prior to the 70s, most vehicles had the engine in front to drive the rear wheels. The drive shaft was the rotating coupling with universal joints that connected the rear of the transmission (usually under the car around the driver’s seat) to the differential assembly at the back of the car. Now with independent suspension and front wheel drive, there ... Read More »

The distribution of air pushing down on a race car. The more downforce, the faster it goes. Read More »

Drag relates to the aerodynamics of the car and affects speed, performance and miles per gallon. The higher the number (the coefficient), slower the car’s performance. The lower the number, the better the car will perform. Read More »

On the BMW F650, the dummy lights are the green light that signifies the bike is in neutral, the blue light that lets you know your high beam is on, the turn signal light and the oil light. Read More »

In 5th gear, the drive shaft is directly engaged to the engine. In all other gears, the power is transmitted from the engine to the gears and then to the drive shaft. With a direct drive powertrain there is no loss of power between the engine and 5th gear thus providing more efficiency. Read More »

Contain two brake shoes inside a drum. As the cable is pulled (by squeezing a lever or stepping on the brake pedal), the shoes are forced to the outside of the drum causing friction that stops the bike. The clutch lever, located on the left handlebar, is squeezed whenever the clutch needs to be disengaged. Easing the clutch lever out ... Read More »

Controls the rebound force of the spring after it has been compressed. A certain amount of force compresses a spring — the spring wants to rebound to its original state with the same amount of force. Damping acts as an opposing force to slow the rebound movement. Read More »

An internal combustion engine in which air is compressed to a temperature sufficiently high to ignite fuel injected into the cylinder where the combustion actuates a piston. Read More »
