C (Motorcycle designation suffix) = Custom (Honda Shadow VT600C)
C.C.I.S. – Cranial Colon Impact Syndrome is a self explanatory term coined by a friend of mine a few years ago for those afflicted and deserving of such praise or attention.
Cafe Chop – Converting a stock motorcycle into a cafe racer is known as doing a cafe chop on a bike.
Cafe Racer – 1. Motorcycles modified to resemble racing motorcycles from the 1950’s and 1960’s. They are called cafe racers because their owner supposedly raced from cafe to cafe in London, where the bikes first appeard in the 1960’s. 2. Sportbike (in Europe Bikers would ride from coffee house to coffee house) designed for style or going fast on twisty roads.

Carma – Like traditional Karma but occurs when cagers do stupid things to bikers. The energy is much more fierce and vengeful and will infect a cager’s ride with radiator leaks, blowouts, bad gas, thrown rods, and overall bad radio reception. These phenomena will only occur when the cager is more than a mile in distance from the biker as to avoid any motorcycle catastrophes. Also works in positive ways when cagers allow a biker plenty of room and are aware of their presence and respect their right to the road. AM reception is unusually clear and the cage experiences a 35% increase in gas mileage.

Charge depleting – A mode of operation used by plug-in hybrid electric vehicles (PHEV), during which electrical energy from the battery powers the vehicle, so that the overall energy stored in the battery is being consumed. At any given moment, the battery may be increasing or decreasing its charge. The battery in hybrid electric vehicles may be charged from regenerative braking and the internal combustion engine (ICE).
Charge sustaining – A mode of operation used by plug-in hybrid electric vehicles (PHEV) to sustain overall battery state of charge. At a given moment, the battery may be increasing or decreasing its charge. The battery in hybrid vehicles may be charged from regenerative braking and the internal combustion engine (ICE). However, in charge sustaining mode, the ICE supplies all the propulsion power of the vehicle. With the aid of the electric drive train, it can operate more efficiently than a conventional vehicle in this mode.

Chopper – 1. A style of motorcycle that appears deceptively light, has a greater angle on the front end than usually seen, and radical styling. The word originates from the post WW2 era when former GIs were looking for performance mods, there was no aftermarket back then and once all engine mods were out of the way the bike’s weight needed to be reduced… Owners began to remove unnecessary components and eventually began to cut away (or “chop”) sections of the bike and frame. Used to be called “bobbing” but the word “chop” became the more popular phrase. 2. A radical customized bike with extended and raked front end, from which all unnecessary parts have been stripped. The early choppers weren’t raked, so the front end was high making it necessary to reduce the size of the front wheel. They are very stable in a straight line, but not to agile in turns. 3. Term originated from owners removing, or “chopping,” features from the motorcycle and adding their own customized detailing. Now refers to a motorcycle with heavily raked front forks, “high-rise handlebars and an increased angle of frame to fork head”. 4. Once described as a custom motorcycle that had all superfluous parts “chopped” off in order to make the bike faster, a chopper today is a type of custom bike that usually has an extended fork, no rear suspension and high handlebars.
