A2 licence: The UK A2 licence allows riders aged 19 and above, to ride a motorcycle with no more than 47 bhp. This can be an A2 bike from the factory or a larger motorcycle restricted down as long as it’s no more than 94 horsepower in standard trim.
ABS: Anti-lock braking systems; a system designed to prevent the wheels locking under extreme braking preventing skidding.

Armour: Protective padding added to garments to help mitigate impacts.
Auto-blipper: What is an autoblipper? Well, put simply it’s a device used to match the engine revs to the road speed for use when changing down a gear. This allows downshifting without the use of the clutch lever, in opposite to a quickshifter.
Apex: The point closest to the middle of the corner.
Aquaplane: This is where the amount of water in front of a tyre builds up faster than the tyre tread can remove it. This water generates a layer of water, causing the tyre to lift off the floor, losing grip.

Chicken Strips: Edges of the tire which are unused. This varies between bikes and rider.
Chopper: a style of motorcycle, usually fitted with high handlebars and footplates.
Crash bobbin(s): protective objects bolted on to the motorcycle to prevent damage during a crash or drop.

Damping: Damping is the process of reducing the oscillation of the spring in a suspension unit when it compresses or rebounds.
Dyno: Dynamometer, used for measuring the performance of an engine or motorcycle. This takes a reading from either the wheel or flywheel. A wheel hp reading will be lower than an engine hp reading due to drivetrain losses.
Disc Brakes: A braking system that uses an external calliper that clamps friction material onto a fixed disc attached to the wheel.
Drum Brakes: a braking system that uses two internal friction shoes that expand into a drum fixed to the inside of the wheel. This system was replaced by the Disc brake.
Double D Ring: a helmet securing system that feeds through two D shaped metal rings.
Dry Clutch: A clutch commonly seen on race bikes. It has no oil inside the clutch and uses airflow to keep the friction plates cool and clean.
DID: a brand of chain for certain bikes. They are the primary brand of chain for many manufacturers.
ECU: an Engine Control Unit, the brain making the engine and other systems like ABS, Traction control and anti-wheelie work.
Euro 4: A motorcycle standard introduced in 2017 to reduce pollution and increase the safety of motorcycles. This is superceded by Euro 5 (see below).
Euro 5: Introduced in 2021it further increases the standards from euro 4 to improve safety and reduce emissions.
End can: an exhaust silencer.
Fairing: A plastic/composite shell placed over the frame and engine, mainly on sports bikes with the primary purpose to reduce drag.
Fettle: to fix, tinker, or play with.
Fork: Motorcycle forks are usually telescopic combining springs and dampers to smooth out the ride for the rider.

Geometry: the various angles which compose a motorcycle including rake, trail, and wheelbase length.
Gear ratio: the difference in size between the input and output gear cogs in the gearbox. These can affect the acceleration and top speed of the motorcycle.
Gore-Tex: a waterproof material applied to clothing. Commonly on textiles, boots, and gloves to ensure waterproof qualities.
Hardtail: A motorcycle with only front forks and a fixed rear end.
Hydroplane: when a thick layer of water builds up underneath a tire preventing traction. See aquaplane

(Go Faster) Juice: fuel
Knee Down: hanging off the bike, and scraping one’s knee on the tarmac as one takes a corner, allowing greater lean angles. It’s also pretty cool.
Lid: a helmet
Leathers: a protective suit made from various types of leather worn both on the road and on track. Other none-leather-based leathers are available.
