For 2021 the chassis has been modified in its rigidity and balance, designed to reach the maximum compatibility between turning and stability. The twin-spar aluminum chassis is immensely light and yet provides the ideal stiffness and strength characteristics required to contain and deliver more than 180kw from the RC213V’s engine to the rear tyre. As well as strength, the chassis features the right amount of carefully designed flexibility to enhance tyre grip.
HRC has adopted 4 cylinder “V” engine with 1,000 capacity to RC213V which can exploit the maximum power while remaining durable enough for the entirety of a season. HRC has reviewed all the details of the new engine, making it lighter, more power and rider-friendly characteristics. For 2021, engine development over the winter has been dramatically reduced and effectively freezing the engines to 2020 specification.
For 2021 the RC213V is fitted with Ohlins suspension front and rear. Providing the essential link between wheel and chassis, the suspension’s job is to keep the tyre in contact with the ground and producing maximum grip as the machine hits the thousands of bumps and ripples encountered on every lap. It’s a crucial link in the performance chain and for this reason both Repsol Honda riders have a dedicated Ohlins technician assigned to him. Working closely together, HRC and Ohlins are continually looking to make improvements.
The lightweight carbon-fibre bodywork plays an important role in making the RC213V as aerodynamic as possible. The 2021 RC213V has a modified fairing to reach the maximum performance balancing acceleration, handling and braking through the management of airflow. In recent years, aerodynamic ‘winglets’ have played an increasingly important role in MotoGP and are some of the most visible changes between each season.
MotoGP tyres are supplied exclusively by Michelin. Each round presents a new challenge for the tyre supplier due to the track layouts and surface of the circuit.
Carbon fiber front brakes are provided by Brembo. These carbon brakes produce incredible stopping power, in term creating some fantastic images of riders entering a corner on just the front wheel as they push to the limit. Wet conditions see some riders continue to use the carbon brakes while other opt to use steel brake disks which can operate at a lower temperature. Yutaka supply these steel brake disks for the RC213V. In both wet and dry conditions, external covers and cooling ducts are sometimes added to help regulate the temperature of the brakes.
