Heard a word mid-race and lost the plot? Look it up here. Every term, flag and bit of tech — explained in one plain sentence, with what to actually watch for on screen.
Brake discs and pads made of carbon — lighter and more powerful than steel, but they only work properly when very hot, roughly 200 to 800°C.
What to watch for
Riders squeezing the brakes on the warm-up lap to build heat in the discs before the start.
A gadget that squats the bike down at the start for a harder launch off the line, then releases.
Why it matters
It lowers the bike's suspension at the start to stop wheelies and maximise launch speed.
In-between tyres for a damp track. MotoGP dropped them after 2016, so riders choose between slicks and rain tyres.
Why it matters
With no in-between tyre, the drying-track gamble is when to pit and swap to the bike on slicks.
A system that lowers the bike on corner exit and straights for better drive and lower drag.
Why it matters
It drops the bike low on corner exit for more drive and less drag down the straight.
Completely smooth dry-weather tyres — no tread, so the maximum amount of rubber touches the track for grip.
What to watch for
Perfectly bald tyres on a dry track; any grooves mean it's a rain tyre.
The pocket of calmer air directly behind another bike. Sitting in it means less wind resistance — so you can carry more speed for free.
What to watch for
A trailing rider tucking in tight down the straight, then darting out sideways to pass.
The pivoting arm that connects the rear wheel to the bike and lets the suspension move.
What to watch for
The long arm running from the frame to the rear wheel, flexing over kerbs and bumps.
The fastest a bike goes on a lap, reached at the end of the longest straight — over 360 km/h at the quickest circuits.
Why it matters
Extra straight-line speed makes passing easier, but races are still usually won and lost in the corners.
The gradual loss of grip as a tyre wears and overheats through a race.
Why it matters
Late-race lap times climb and riders start sliding — managing 'deg' often decides the winner.
Grooved tyres that channel water away so the bike can grip a wet track.
What to watch for
Deep grooves flinging up spray — the tell-tale sign the track is properly wet.
Small wings on the bodywork that create downforce to keep the front wheel down and improve stability.
What to watch for
Fins and wing shapes on the front fairing, especially either side of the bike's nose.
A violent crash where the sliding rear tyre suddenly grips again and flicks the rider up and over the top of the bike.
What to watch for
The rear tyre violently kicking upward mid-corner, throwing the rider clear of the bike.
How far the bike is tipped from vertical through a corner — MotoGP riders pass 60°.
What to watch for
Elbow and knee sliders scraping along the tarmac in the fast, sweeping corners.
Deliberately hiding your true pace in practice so rivals underestimate you.
What to watch for
A quick rider mysteriously down the timesheets, hiding their true pace until it matters.
The innermost point of a corner — the tightest part of the turn that a rider aims to clip to carry the most speed onto the next straight.
What to watch for
Riders brushing the inside kerb at the middle of a bend, just before the bike stands up and fires out.
A quick sequence of tight, alternating corners (left-right or right-left), often built to slow the bikes down.
What to watch for
Riders braking hard and flicking the bike from one side to the other — a favourite spot for a late pass.
The strip of track that dries first as rubber and warmth build up, giving the most grip.
What to watch for
A darker, cleaner ribbon snaking around the circuit — riders hunting grip glue themselves to it.
A very tight, slow corner that almost doubles back on itself.
What to watch for
Hard braking into a near U-turn, then riders pick the bike up and fire out — a classic overtaking spot.
The fastest path through a corner — usually wide on the way in, clipping the apex, then wide again on the way out.
What to watch for
Riders tracing almost the same path lap after lap — until a rival dives inside it to pass.
A race where the weather changes and riders pit to switch bikes without the race stopping.
Why it matters
The whole order can reshuffle in seconds as riders gamble on exactly when to switch bikes.
Getting to the first corner in the lead off the start line.
What to watch for
The rider who nails the launch and pops out first at turn one — not always the pole-sitter.
Moving before the lights go out at the start — it earns a penalty.
Why it matters
Move before the lights go out and a penalty is coming — watch for the long lap that follows.
A penalty that sends a rider through a longer detour off the racing line, typically costing two to four seconds.
Why it matters
You'll see a rider peel off onto a painted loop and rejoin a place or two further back.
The fenced-off working area behind the pits where teams, hospitality and motorhomes are based.
What to watch for
The maze of team trucks and hospitality units behind the garages, buzzing between sessions.
A controlled area where the top bikes are held after the session for checks, with no team work allowed.
Why it matters
No spanners allowed — bikes are locked away for scrutineering after the flag.
A hand-held board teams hang out at the track wall to signal gaps and messages to their rider.
What to watch for
A crew member leaning over the wall with a board of numbers as their rider flashes past.
The crew chief, mechanics and engineers who prepare, set up and repair a rider's bikes in the garage.
What to watch for
Mechanics swarming over the bike between sessions while the crew chief talks set-up with the rider.
The slow lane beside the track where teams work on the bikes and riders enter and exit.
What to watch for
Riders slowing right down and peeling into the garages alongside the main straight.
In MotoGP, coming into the pit lane mid-race to swap to a second bike — usually because the weather has changed.
Why it matters
There are no routine stops for fuel or tyres, so a pit stop almost always means rain has arrived or the track is drying.
First place on the starting grid, earned by the fastest qualifying lap.
Why it matters
Starting from the cleanest, shortest line into turn one is a genuine head start.
Sessions before qualifying where riders set up the bike; the top ten in Friday afternoon's Practice go straight to Q2.
Why it matters
Finish outside the top ten in Friday's Practice and you face the Q1 shootout — every lap counts.
The timed sessions that set the starting order, split into Q1 and Q2 for the front rows.
What to watch for
Single fast laps on fresh tyres, riders hunting a tow — the grid order takes shape.
A car that follows the riders on the warm-up lap and the whole first lap, ready to help after a crash — unlike in F1, it never leads the race.
What to watch for
The car with roof lights tucked in behind the pack on lap one — after that, the racing is left to the riders.
A short Saturday race over half the distance, awarding points to the top nine finishers.
Why it matters
Half the laps and no pit stops — it's flat out from the lights, with championship points on the line.
The title for teams: the points of a team's two riders are added together after every Sprint and Grand Prix.
Why it matters
Two steady points-scorers can beat a team built around one star — and points from a stand-in rider count too.
A rider employed by a manufacturer to develop the bike away from race weekends, who sometimes races as a wildcard or a replacement.
Why it matters
The rules limit how much the race riders can test, so new parts are often proven by the test rider first.
The painted edges of the track; running beyond them can cancel a lap time or earn a warning.
Why it matters
Run wide over the green paint and a lap time or position can be scrubbed.
The lap to the grid before the start, used to heat the tyres and brakes.
What to watch for
Riders weaving hard and grabbing the brakes on the lap to the grid to heat everything up.
Two yellow flags waved together: the hazard is partly or wholly blocking the track — slow down, no overtaking.
What to watch for
Two yellows waved together mean the obstacle is on the track itself, not beside it — expect something in the path.
A flag that stops the session immediately, usually for a crash or weather.
Why it matters
Everyone returns to the pits and the race may be restarted or its result shortened.
A flag signalling that riders may swap to a second bike — usually as rain arrives.
What to watch for
A white flag at the marshal posts as rain arrives — the cue riders can swap bikes.
A warning of danger ahead — slow down and do not overtake in that zone.
What to watch for
Marshals waving a yellow flag trackside, usually near a crash or a stranded bike.
