Moto2 vs. Supersport: Significant investment, modest performance advantage

The Moto2 and Supersport categories take different technical approaches. Whilst in Moto2, chassis developed specifically for racing are combined with a standardised engine derived from the Triumph production engine, the motorcycles in the Supersport World Championship are based much more closely on production machines available to the public. In terms of technical complexity and the associated costs, the categories differ significantly. On the racetrack, however, the difference is surprisingly small.

One rider who can judge this first-hand is Albert Arenas. The 2020 Moto3 World Champion competed in the Moto2 World Championship for five years before switching to the Supersport World Championship last winter. There, the Spaniard quickly got to grips with his new Yamaha machine and went into the summer break with an 82-point lead over ZX-Moto rider Valentin Debise.

After many years on Moto2 machines, Arenas was particularly surprised by just how small the differences are compared to the more production-based technology. “Of course, you can describe them as production-based or as prototypes, but at the end of the day they’re motorbikes – and they’re really powerful,” explained the 29-year-old.

Although in Moto2 the chassis in particular is designed without compromise for track use, whilst a Supersport motorbike is based on a production model, the performance figures are comparatively close. The performance advantage of the significantly more complex Moto2 machine is smaller than the differing technical concepts and costs might suggest.

Topic of the week: Aprilia comeback? The truth is: Aprilia never went away!

Four weeks ago, Aprilia headed into the summer break from Germany with a badly injured Marco Bezzecchi. The response came from the heart of British motor racing: ‘Together we are strong!’

Arenas also noted after his switch: “The motorbikes are very similar. You’d be surprised if you could try both.” For the Spaniard, it is the rider’s skills rather than the different designs that are decisive. “In the end, it’s all about the speed you can achieve and the feel you get when riding.”

How the high rigidity of the Moto2 bike makes itself felt

Arenas sees the biggest difference in the chassis and its stiffness. The Moto2 design, developed specifically for racing, really comes into its own, particularly in fast corners. “The difference is greatest in fast corners because the motorbike isn’t as stiff and stable as a Moto2,” explained the World Championship leader.

This is precisely where it becomes apparent that the Moto2 chassis can be developed without the design constraints of a road motorbike. With a supersport machine, key characteristics of the production model are retained despite extensive modifications. However, Arenas emphasised: “Otherwise, they’re really very, very similar.”

The ergonomics also contribute to the different riding feel. “If you were to alter the fuel tank and the riding position slightly, it would be even more similar,” explained the Spaniard. Arenas pointed out that some manufacturers have already developed their Supersport bikes more in the direction of a dedicated racing machine, using more modern solutions for the fuel tank, swingarm and other components.

Triumph, of all manufacturers, provides an interesting technical link between the two categories. The British manufacturer fields the Street Triple 765 RS in the Supersport World Championship. Its three-cylinder engine also forms the basis for the Moto2 standard engine. The technical conditions, however, differ. “I think the power is more heavily regulated here. We have lower revs,” noted Arenas, referring to the Supersport World Championship.

This results in a remarkable balance between technical and financial investment on the one hand, and actual performance on the other. Moto2 offers greater design freedom, particularly when it comes to the chassis, and is considerably more expensive.

Nevertheless, the Supersport machines – which are much closer to production models – manage to come astonishingly close to the performance of the middle Grand Prix class on the racetrack.

In any case, Arenas finds little to complain about on his new machine. “The bike works incredibly well and is a joy to ride,” enthused the Spaniard. “I just concentrate on riding and enjoy the races, the battles and the competition.”
