Motorcyclists have a language all their own. Some of it describes the motorcycle, some of it explains what happens on a group ride, and some of it comes from decades of motorcycle, racing and club culture.
If you've ever looked at an event flyer that says “Reg. 9:00 AM — KSU 10:30” and wondered what the hell everyone was talking about, you're in the right place.
This isn't intended to be the definitive dictionary of everything anyone has ever said around a motorcycle. It's a practical collection of the terms, abbreviations and slang you're likely to encounter while riding, attending motorcycle events, working on motorcycles or hanging around the motorcycle community.
Motorcycle slang varies by region, generation and community. Club terminology can vary from one organization to another. Context matters.
A term associated with outlaw motorcycle-club culture. Its commonly repeated history connects it with the idea that 99 percent of motorcyclists are law-abiding citizens, leaving the remaining one percent outside that description. Considerable folklore has accumulated around the term over the years.
Represents M, the 13th letter of the alphabet. What the M represents can vary by rider, club, region and era, so the meaning of a 13 patch shouldn't automatically be assumed.
A name used by motorcycle-rights organizations involved in rider advocacy, education, legislation and motorcycle events. Washington riders will frequently encounter ABATE of Washington and its local chapters.
A motorcycle designed for travel that may include pavement, gravel and unimproved roads. ADV motorcycles generally combine touring capability with some degree of off-pavement ability.
Tall handlebars that position the rider's hands substantially higher than conventional handlebars.
All The Gear, All The Time. A philosophy of wearing appropriate protective motorcycle gear every time you ride.
Biker slang for the passenger riding behind the motorcycle operator. Passenger, pillion and two-up are other terms you'll encounter.

A motorcycle gathering that includes a ceremonial blessing of riders and motorcycles, commonly held near the beginning of the riding season.
A motorcycle customized in a stripped-down style traditionally involving removal or shortening—“bobbing”—of bodywork and other equipment.
A cage is a car or other enclosed vehicle. A cager is the person driving it.
A mechanical device that mixes fuel and air for an engine. Carburetors were standard motorcycle equipment before electronic fuel injection became commonplace.
A system used to provide the richer fuel mixture needed for starting some cold carbureted engines. A true choke and an enrichment circuit accomplish this differently, although riders commonly call both a choke.
A substantially customized motorcycle, traditionally involving changes to the frame, front end, rake and overall proportions.
Not every customized motorcycle is a chopper, and not every chopper is a hardtail.
The primary insignia identifying a motorcycle club and its members. Depending upon the organization, colors may include a center patch, rockers, club initials, chapter identification and other patches.
A device that temporarily reduces cylinder compression so an engine can be turned over more easily. Particularly useful with large-displacement or high-compression engines. Compression releases may be manual or automatic.
The steering input used to initiate and control motorcycle lean at normal riding speeds. Pressure on the handlebar initiates lean in the desired direction.
Biker slang for an older driver piloting a large or cumbersome vehicle—often a motorhome, RV or vehicle towing a boat or trailer—slowly or poorly enough to obstruct traffic.
Frequently discovered immediately before the best section of twisties you've seen all day.

GPS Exchange Format. A common file format for sharing GPS routes, tracks and waypoints.
GMRW uses GPX files extensively with our Washington motorcycle Ride Maps.

A hand-operated gearshift lever positioned beside or behind the rider and operated by reaching down with one hand.
A jockey shifter is often paired with a foot-operated clutch on custom motorcycles, but the shifter and clutch are two separate things.

When MC appears as part of club colors or insignia, it may have organizational significance beyond simply describing a group of people who ride motorcycles.
Traditional American motorcycle slang generally referring to Japanese motorcycles and sometimes more broadly to non-American motorcycles.
Foot controls positioned approximately beneath the rider rather than substantially forward.
Much Love, Loyalty, Honor & Respect. A sign-off or expression used within parts of motorcycle/biker culture to convey brotherhood, loyalty, respect, and affection.
Traditional biker slang for a committed partner. Exact meaning and usage vary among riders and motorcycle communities.
A motorcycle primary-drive system operated without the conventional outer primary cover, leaving components such as the belt or chain and clutch assembly exposed.

A motorcycle show or gathering emphasizing appearance and display, often including judging or people's-choice awards.
A group-riding formation in which motorcycles travel one behind another rather than staggered.

It's frequently confused with a jockey shifter, but clutch operation and gear selection are separate systems.
A rapid and potentially violent oscillation of the motorcycle's handlebars and front end.
The expression is sometimes casually used for other motorcycle wobbles, although not every wobble is technically a tank slapper.
The tendency to stare at an obstacle, hazard or particular point and unintentionally steer toward it instead of looking through the desired path of travel.
A motorcycle-club patch arrangement generally consisting of a center patch with separate upper and lower rockers.
The significance of a three-piece design varies by organization and shouldn't automatically be inferred from appearance alone.

This particular collection of motorcycle terms gets mixed together constantly:
Jockey shift = how you select the gear.
Suicide clutch = how you operate the clutch.
Open primary = how the primary drive is enclosed—or isn't.
Kicker = manually turns the engine over for starting.
Compression release = makes the engine easier to turn over.
A motorcycle can have one, several or all of them.
Seeing an open primary tells you nothing about how the motorcycle shifts. Seeing a jockey shifter doesn't automatically mean it has a suicide clutch. And a compression release doesn't start the engine—it simply makes a high-compression engine easier to turn over.
Motorcycle-club terminology deserves some additional caution. Meanings and traditions can vary between clubs, chapters, regions and generations. Some expressions follow widespread patterns while others belong specifically to individual organizations.
A patch, acronym or piece of clothing also shouldn't automatically be interpreted as proof that someone is a member of a particular club.
A common motorcycle-club loyalty expression built around the name or initials of a particular club.
The basic construction is:
[Club] Forever — Forever [Club]
For example:
AFFA — Angels Forever, Forever Angels
BFFB — Bandidos Forever, Forever Bandidos
Other motorcycle clubs use the same FF construction with their own initials. The important thing is understanding the pattern rather than trying to memorize every possible combination.
A common motorcycle-club support expression meaning:
Support Your Local [Club]
The club's name or initials are incorporated into the abbreviation.
For example, SYLB can mean Support Your Local Bandidos, while other clubs use the same construction with their own identifying letters.
An SYL patch, sticker, shirt or other item expresses support for the organization named. It should not automatically be interpreted as proof that the wearer is a patched member of that club.
A patch, shirt, sticker or other insignia expressing support for a particular motorcycle club or organization.
A support patch does not necessarily indicate membership in the organization being supported.
In motorcycle-club usage, generally a member who isn't attached to a conventional geographic chapter or who belongs to a designated Nomad chapter.
Exact organization and meaning vary by club.
Language sometimes appearing on motorcycle-club event flyers indicating that attendance by other clubs is by invitation rather than generally open to every club or to the public.
These events may advertise a date, general area or other information publicly while distributing the exact location privately to invited clubs or participants. Consequently, a flyer without a street address isn't necessarily incomplete.
When “Clubs by Invite Only” appears alongside other restrictions such as “No Cops, No Lops,” it generally signals a private or controlled-attendance club event rather than an ordinary public motorcycle gathering.
An old-school phrase sometimes appearing on private motorcycle-club event flyers indicating restrictions on who is welcome at the event.
“No Cops” is straightforward. The precise expansion and use of “Lops” is less consistently documented in publicly available sources, and club terminology can vary. Rather than pretending there's one universally documented definition, GMRW treats the phrase according to its practical context: an attendance restriction associated with private club events.
It is often seen alongside wording such as “Clubs by Invite Only,” which further indicates that the event isn't intended as an ordinary open-to-the-public motorcycle gathering.
A few common pieces of flyer shorthand tell you quite a bit about an event.
Reg. 9:00 AM — KSU 10:00 AM means registration begins at 9:00 and the ride leaves at 10:00.
Rain or Shine means the organizers intend to hold the event despite ordinary changes in weather.
Clubs by Invite Only means exactly what it sounds like: other clubs attend by invitation.
And a combination such as “No Cops — No Lops — Clubs by Invite Only” should not be read like ordinary ride instructions. It is telling you that you're looking at a private or restricted club event, and the location or additional information may intentionally be distributed through private channels.
That's also why not every motorcycle flyer floating around Facebook belongs on a public motorcycle-events calendar.
Motorcycle language isn't standardized.
It developed over generations in garages, racetracks, motorcycle clubs, dealerships, bars, rallies, group rides and alongside broken motorcycles on the side of the road.
Some terms are nearly universal. Others are regional. Some belong primarily to a particular generation of riders. Club terminology can be organization-specific, and plenty of biker folklore has been repeated so many times that nobody remembers where the hell it started.
That's part of the culture.
The GMRW Rider Glossary isn't intended to settle every barroom argument ever conducted over a V-twin. It's here to help riders understand the terminology they're likely to encounter while riding motorcycles and participating in the Washington motorcycle community.
And when we discover another good one, we'll add it.
Kickstands Up. Don't Miss the Ride.
