The measurement of cranking amperes a battery can deliver over a period of 30 seconds at 0°F (-18°C). Commonly used to rate automotive batteries, it is not usually used to rate motorcycle batteries. Motorcycle batteries are rated in Amp/hours (A/h), that is, how many hours can a fully charged battery supply one amp of current [...]

Also known as a condenser. An electrical component that is made up of two metal sheets separated by an insulator. It is designed to store an electrical charge. A popular “hop-up” in the racing and off-road community is to replace the battery in a motorcycle with a large capacitor. The capacitor stores enough electrical energy [...]

Hydraulic disc brake systems utilize brake calipers to hold and actuate the brake pads. The brake pads are held in place so that the brake disc is positioned between them. The caliper has one or more pistons which use hydraulic pressure to push the brake pads against the brake disc which in effect squeezes the [...]

Christini Technologies Inc. designs and builds an All Wheel Drive motorcycle. In their fully mechanical system (no hydraulics or electronics,) power is in fact sent to both wheels at different ratios making it all wheel drive. The front wheel free-wheels until the rear wheel slips. Drive ratios to the front are between 60% and 80%. [...]

The part of an engine where combustion of the air-fuel mixture takes place in the cylinder head. In two and four-stroke engines, and diesel motors, the combustion chamber refers to the space between the cylinder head and piston crown.

A one-piece engine cylinder made of cast iron with a precision machined cylinder bore. The porosity of cast iron retains oil for piston and ring lubrication, but it is very heavy. Many motorcycles have aluminum cylinders with cast iron sleeves to help reduce weight.
