Cafe Racer - Sportbike (in Europe Bikers would ride from coffee house to coffee house)
Cage - A car, truck, or van. The sworn enemy of motorcyclists, more commonly known as automobiles. The name stems from being all cooped up inside a closed shell, with no contact with the outside air.
Cager - A person driving a car, truck, or van. Cage operator, or driver.
Can - Muffler (AUS)

Carb - Carburetor, Fuel Management System
Carburettor - The part of the bike that mixes air and fuel in correct proportions before it is entered into the engine cylinder(s).
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.
Carving - Refers to hard fast cornering on roads with many curves, stems from laying the bike down to a nearly horizontal position and "carving" a line through the roadlike a knife.
Catwalk - Riding a motorcycle on the rear wheel only, more commonly known as a "wheelie"
CBT - 'compulsory basic training' a one day training course which all newbies must complete before being allowed to ride on the road in the UK. (It also stands for 'Cognitive Behavior Therapy' which many car drivers could do with to improve the way they relate to bikers.)
Chain - The word chain usually refers to primary drive, in which sense it means the chain transferring power to the rear wheel. As opposed to the two alternatives, shaft or belt drive, the chain is a light-weight solution and does not cause lag in throttle response or elevation effects. On the other hand it is a solution that needs a lot of maintenance.
Chase Vehicle - Van or truck that follows a pack of riders on a run to assist or haul any bikes that might break down
Checkbook Biker - Same as "InstaBiker" Someone who goes down to the dealership and writes a check for a new bike and new gear.

Chickenwing - Honda Gold Wing
Chopper - A style of motorcycle that appears deceptionally 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.
Chrome-Slut - Those addicted to putting on more and more chrome, regardless of the functionality.
Chromosexual - That one biker who keeps adding more and more chrome, a chrome-overkill.

A patch with or simply the lettersMC will often accompany the club name. Treat these people with utmost respect.
Clubber - One who has club affiliation
