Understanding MotoGP: The Classes, the Technology, and What the Broadcast Doesn't Explain
MotoGP broadcasts assume a level of technical knowledge that casual viewers rarely have. The gaps — why the rider's knee drags, what the winglets do, why the bike squats on acceleration before the turn — are real, and filling them makes watching the sport substantially more rewarding. This covers the essential structure and technology.
The four classes
MotoGP events run four classes in sequence across the weekend. Understanding the distinctions is the first step to following the sport.
MotoGP is the premier class, running prototype machines built specifically for racing. There is no production equivalent to a MotoGP prototype; every element is purpose-built or specifically manufactured. The engines are 1000cc four- stroke units with a maximum of four cylinders, producing approximately 290 horsepower at peak — though this figure is deliberately imprecise, as manufacturers do not publish power outputs and the figure changes with software settings. The bikes weigh approximately 157 kg including the rider.
Moto2 runs a single-specification chassis (Kalex has dominated the Moto2 frame market for over a decade) with a single-specification Triumph 765cc three- cylinder engine. Moto2 is where MotoGP careers are made; the class's competitive structure means every ride is contested by riders who could transition to MotoGP within one to two seasons. Watch the Moto2 grid and you are watching the next decade of MotoGP careers.
Moto3 runs 250cc single-cylinder engines in full factory-developed chassis, producing approximately 50 horsepower in machines that weigh under 150 kg. The power-to-weight ratio produces unique racing: Moto3 races are drafting exercises, with enormous packs running together to the final corner because the slipstream advantage is so significant that breaking away early is almost always counterproductive. Individual Moto3 laps can involve 30 riders within one second of each other.
MotoE runs full-electric prototype motorcycles and was introduced in 2019. The class is currently limited by battery weight and capacity; lap times are significantly slower than Moto3 despite the full-electric torque advantage. MotoE serves as a development programme for electric motorcycle technology rather than as a competitive class with independent significance; its future on the calendar is subject to technology development.
Tyres: Michelin since 2016
Michelin became the sole MotoGP tyre supplier in 2016, replacing Bridgestone. Each rider receives an allocation of front and rear tyres per weekend, from which they select their race tyres on Saturday evening and specify to the tyre technicians. Unlike Formula 1, where compounds are designated by Pirelli, MotoGP riders and crew chiefs have significant flexibility in their tyre selection from the allocation provided.
The tyre warmers visible on the grid before the start are electric heating blankets that bring the tyre carcass to working temperature before the formation lap and start. MotoGP uses high-temperature tyre warmers extensively; without them, a cold tyre would provide insufficient grip at the moment of highest stress — the opening lap in race traffic. The debate over tyre warmers has been ongoing within the championship for several years: proposals to ban them in the name of reducing cost and increasing grid variance have met resistance from safety-focused riders who argue that a cold tyre on the formation lap presents genuine injury risk.
Winglets: the aero debate
Winglets — small aerodynamic appendages attached to the front fairing of MotoGP machines — became widespread from 2016 following Ducati's introduction of devices that reduced front-end lift under hard acceleration. The FIA and MSMA (manufacturers' association) subsequently introduced regulations defining permitted winglet dimensions and placement. The current winglet packages on MotoGP machines are sophisticated multi-element devices that contribute to aerodynamic downforce front and rear, cooling airflow management, and stability under braking.
The winglet debate centres on the increasing aerodynamic complexity that requires substantial development resource and potentially reduces the accessibility of competitive motorcycle racing. For spectators, winglets are visible on the front fairing of the bike as horizontal flat extensions; their effect is not visible but contributes to the stability that allows modern lean angles and speeds.
Ride-height devices: holeshot and rearsets
The holeshot device, widely adopted from 2019 onward, is a mechanical mechanism that lowers the rear of the motorcycle at the start, pre-loading the suspension to reduce wheelie tendency and maximise traction from the line. It is activated manually by the rider and releases automatically when braking or chassis loading exceeds a threshold. The rearset device — a similar system for the rear suspension — serves the same anti-wheelie function for exit of slow corners.
These devices have been controversial: critics argue they represent a shift toward mechanical complexity that replaces rider skill in managing wheelspin; proponents argue they are a natural extension of the engineering development that has always characterised the class. The practical effect is that the margin gained at the start line — previously determined partly by raw rider skill and partly by mechanical setup — is now more consistently determined by the device's function.
Lean angles
The lean angles achievable by a modern MotoGP machine at the limit are routinely above 65 degrees from vertical — in some cornering phases, above 68 degrees. At these angles, the tyre contact patch is on the extreme shoulder of the tyre, the knee slider is making contact with the tarmac, and the elbow occasionally does too. The physical sensation for the rider involves sustained lateral loading that produces fatigue over a race distance; the upper-body and core conditioning of MotoGP riders is trained specifically for this.
The lean angle data published by circuits during MotoGP weekends — shown on broadcast overlays as the bike silhouette tilts in the corner diagram — provides a real-time view of how each rider uses the available tyre contact.
Grid procedure
MotoGP uses a 40-minute warm-up window on Sunday morning (on sprint weekends this has been modified); the race grid assembly procedure then follows. Riders enter the grid in grid order, tyres are warmed, and the five red lights sequence counts down the start. The formation lap — one full lap of the circuit to warm tyres and brakes from the already-warmed state — precedes the lights sequence. Teams may send engineers to the grid for the grid assembly period before clearing the circuit when the formation lap commences.
Factory and satellite teams
MotoGP teams operate on two tiers. Factory (works) teams — Ducati Lenovo, Repsol Honda, Monster Energy Yamaha, Aprilia Racing, and the Gresini Ducati programme — receive the most current motorcycle specification, full factory technical support, and their riders receive first priority on development parts. Satellite teams — Pramac Ducati, Trackhouse Aprilia, Tech3 KTM, and others — receive motorcycles on a one-generation delay (or the current specification by agreement) and operate with reduced factory engineer support.
The distinction has blurred in the Ducati era: Pramac and Gresini have at various times run current-spec machinery ahead of some factory riders in the championship. The satellite structure allows manufacturers to expand their grid presence beyond two factory entries while managing development resource.
The rider transfer market
MotoGP contracts typically run on two-year cycles with options. The transfer window operates informally from mid-season, with rider announcements accelerating after the summer break. Unlike Formula 1, where team loyalty and multi-year contracts are the norm at the front, MotoGP's rider market is more fluid: the motorcycle's character can suit or not suit a specific rider's style in ways that are difficult to predict before the season, creating genuine mid-contract pressure and end-of-season reshuffles.
