MotoGP engines are the heart of the sport, driving both performance and innovation. For new fans, understanding engine capacities, configurations, regulations, and development is crucial. Here’s a simplified breakdown of what makes MotoGP engines so special.

What Engines Are Used in MotoGP?

MotoGP engines are unique, as they are purposefully designed for racing. They can reach speeds of up to 349 km/h (217 mph) and are not available for public purchase, even after retirement.

Key Specifications:

• Maximum displacement: 1000cc
• Cylinders: Four
• Bore size: Maximum 81mm
• Transmission: 6 gears only
• Turbocharging: Not allowed

Engine Configurations: Inline-Four vs. V4

Teams can choose between two engine configurations, each with unique advantages:

1. Inline-Four Engines:
   • Longer crankshaft provides stability and better cornering performance.
   • Favored for high cornering speeds using U-shaped racing lines.
2. V4 Engines:
   • Shorter crankshaft allows higher RPMs and greater straight-line speed.
   • Uses V-shaped racing lines and often dominates on straights.

On the Track:
In 2024, only Yamaha used inline-four engines, while all other manufacturers have adopted V4 configurations.

Manufacturers and Engine Development

Manufacturers develop engines for their factory teams and supply satellite teams. The key manufacturers for 2024 are:

• Ducati
• KTM
• Aprilia
• Honda
• Yamaha

Factory Teams must use the same engine for both riders, while satellite teams can use different engine specifications. Each season, teams are allowed 7 engines per rider, increasing to 8 if the calendar includes 21 or more races.

The Cost of MotoGP Engines

MotoGP engines are among the most expensive parts of the bike. Costs include:

• Single engine: Up to $287,000 USD
• Entire bike: Between $1–4 million USD

Teams typically require 7–10 engines per rider for racing and testing, making engine development a significant financial investment.

Regulations and Engine Monitoring

MotoGP enforces strict regulations to ensure fairness and control costs. Key rules include:

• Engine parts are stored in tamper-proof cases for inspection throughout the season.
• Manufacturers are ranked (A, B, C, or D) based on performance, which affects engine allowances and development rights.

Managing Engine Usage

A MotoGP engine must last approximately 1700 km, covering 12,000 km per season. Teams create an engine plan to allocate engines strategically:

• High-load tracks (e.g., Malaysia, Qatar): Use new engines for maximum performance.
• Lower-load tracks (e.g., Sachsenring): Use older engines with high mileage.

Adjusting RPM limits allows teams to extend engine life or extract more power when needed, balancing performance and durability.

Concession Points and Rankings

MotoGP uses a concession system to balance competition:

• Manufacturers earn points based on performance and are ranked from A to D.
• Rankings determine benefits like engine allowances, testing privileges, and aerodynamic updates.

For Example:

• Rank A (Ducati): Fewer allowances, stricter development limits.
• Rank D (Yamaha and Honda): More freedom to develop and test engines.
