Pirelli in MotoGP: ‘Every time the tyre manufacturer changes, the bikes change so much’

MotoGP

In a little more than a year and a half MotoGP will undergo its biggest tech shake-up since 2002, with the motorcycles fully redesigned for new rules and new tyres. So, will they use modified WSBK tyres? When will Pirelli testing start and will the change fix MotoGP’s-tyre pressure problem? We asked Pirelli’s main man for the answers

Last week MotoGP dropped a bombshell: from 2027 the championship will switch from Michelin tyres to Pirelli, coinciding with a reduction in engine capacity from 1000cc to 850cc, reduced downforce aerodynamics and the banning of holeshot and ride-height devices.

This represents by far the biggest technical shake-up since the advent of all four-stroke MotoGP in the early 2000s. In the past, major rules rewrites have never coincided with a change of tyre spec, which arguably has more effect on motorcycle design than anything else.

Thus MotoGP’s status quo could be turned upside down two years from now, depending on which manufacturers adapt best to the new regulations and tyres.

Some fans might agree that the championship is more than ready for a change in the status quo.

Pirelli’s move suggests the Milan company has decided it wants to be in the limelight with the premier class, not only in the shadows with Moto2 and Moto3, which it took over last year.

Now Pirelli and MotoGP’s five manufacturers have a race on their hands to get ready for the switch, which will take place immediately after next year’s final grand prix.

The long-time World Superbike tyre supplier has already started working on creating its first MotoGP tyres, which will be significantly different from its WSBK tyres, which are 125/70-17 fronts on 3.5in rims and 200/65-17 rears on 6in rims. Michelin’s current MotoGP slicks are 120/60-17 fronts on 4in rims and 200/69-17 rears on 6.25in rims.

Finally, might the tyre switch be the final incentive that convinces reigning WSBK champions BMW to move to MotoGP?

 


Mat Oxley: Last year you told me you can’t use production-based tyres in MotoGP, which is your concept in all your other championships, so you weren’t interested in the premier class at that time. What changed your mind?

Giorgio Barbier, Pirelli racing manager: We have shown we can do a good job in Moto2 and Moto3, using standard tyres, using the manufacturing process of our normal production tires, so now we can work at the different concept of MotoGP tyres.

What can we do for the future of MotoGP? We can simplify matters to try and give better quality products, equal for everyone, which is what we’ve done in all the other championships. Sure, MotoGP bikes are different, they are prototypes, so they will need special attention from our side, but we think it will be possible to do this job using the machinery processes we already have.

Your tyres deflect (squish) more than most to create a bigger footprint and more grip – how will that work with MotoGP bikes, with carbon brakes, aerodynamic downforce and so on?

There are some features of MotoGP bikes that won’t change, even with the new rules. What you mentioned, for instance. At the same time I expect the manufacturers will be able to change the reaction of their bikes quite well [to our tyres], using the chassis, suspension and engine controls.

It’s a fact that every time the tyre manufacturer changes, the bikes change so much and go forward with the tyres. All the manufacturers know the characteristics of our tyres. I don’t think their character will change at the start, but for sure we will have to work and we will find a compromise with the manufacturers.

I think all the MotoGP manufacturers will need to compete in WSBK for the next year and a half to have proper knowledge of your tyres!

It’s funny, because, especially with all the MotoGP and Moto2 riders that have joined World Superbike and World Supersport in recent years, they sometimes tell me, ‘This carcass we tested might be good for MotoGP’. Especially Alvaro [Bautista] – the last time we were in Australia [February’s Phillip Island WSBK round] he told me the specs we brought this time could be very good for MotoGP. Okay, we’ll see!

Since MotoGP went to spec tyres in 2009, with Bridgestone, then Michelin from 2016, there’s always been an imbalance in the bikes – they had to be biased to the Bridgestone front and then to the Michelin rear, so will your tyres be more balanced?

We are still finalising many things within our contract with Dorna, but the most important thing is to start working as soon as possible with Dorna, the MSMA [the manufacturers’ association], with the FIM [the governing body] and the manufacturers to understand when we will be able to start testing.

Two years is nothing, because riders and teams have to do the race season and the standard tests with the French manufacturer. And so they have to find the time and a way to let us test. This is a matter of rules which they must fix together, so we are just waiting in order to start our work.

Can you avoid MotoGP’s front tyre over-pressure problem, caused by super-hot motorcycles racing in packs, plus the heat from carbon discs and the stress from downforce aero?

For sure, that’s something that’s a characteristic of this kind of bike, the braking, the aerodynamics and so on. MotoGP front pressure will be something interesting for us – we’d like to approach this from the point of view of our own casing.

We will start with the current MotoGP rim sizes, to stay with what the teams know, then we will make new tyre sizes and see what we can do. It’s a matter of experience.

When did you start talking to Dorna about the MotoGP project?

We started talking when they got World Superbike! [In 2012 Dorna was gifted WSBK by MotoGP owners Bridgepoint, which had bought Swiss sports marketing company Infront Sports for its football contracts. By chance, Infront also owned WSBK].

“It’s a good thing to have a single supplier for all Dorna’s championships”

Speaking frankly, we started our MotoGP project in 2021, with the MiniGP series, with Ana Ezpeleta [Dorna CEO Carmelo Ezpeleta’s daughter]. In this way we first approached the world of Dorna, the Spanish world of Dorna. This was good for us because we started working with kids riding little bikes, making new ten and 12-inch tyres. We showed Dorna that we can invent new tyres from one day to another. Then we went ahead with the Road to MotoGP talent cups, JuniorGP and Moto2 and Moto3.

We produced good tyres that were faster, so Dorna started to look at us in a different way from the past and probably that gave us the possibility to join this project.

When did you start talking specifically about being the spec supplier for the MotoGP class?

One day I will write a book!

I know some journalists have spoken to Michelin MotoGP boss Piero Taramasso since the Pirelli/MotoGP announcement and he’s said the reason for this change is because Dorna wants the same tyre supplier across all its championships, which didn’t interest Michelin. But when I was at last month’s Sepang tests a Michelin spokesperson told me they were considering getting out of MotoGP partly due to the controversy surrounding Jorge Martin’s crash.

This kind of thing can happen. It’s not so nice to be this situation, for a tyre company or for a team, but the result was that the world champion was out of the opening races, which is bad.

In my opinion it’s important that Dorna understood that it’s a good thing to have a single supplier for all its championships. We have shown we can do this, from Formula 1 to World Superbike and the other classes.

We are able to do all of this, so this gave the promoter the option to talk with just one tyre partner, to have one big sponsor from this point of view and to give an image boost for the tyre manufacturer.

These are the things that might’ve changed Dorna’s mentality. In any case, I suppose they understood that from Pirelli’s work in MiniGP, JuniorGP, Moto2 and Moto3 that we can do these things, so now they are trying MotoGP with us as well.

MotoGP has a problem with high corner speeds, which are threatening its greatest tracks – Mugello, Phillip Island and Brno – so did this subject feature in your negotiations with Dorna? Basically, that MotoGP can’t keep chasing faster and faster lap times?

Not precisely from this point of view. We’ve had a lot of this kind of talk over the years in Superbike, where we play different roles and give them different solutions. For example, when the super pole race was born – around ten laps and 50 kilometres – we helped by giving special tyres – the SCQ – to make the show better and help the riders enjoy these races.

But this hasn’t happened with MotoGP’s sprint race. Who made choice, the [tyre] manufacturer or Dorna? I don’t know, but we will talk about this with Dorna. For sure, we’d like to bring something different, we’d like to have a better show for everyone, because this is part of our job – to help the promoter and the riders to have something better.

I understand all of this, we are all playing this together and we have some plans. I think this is the way we will follow in MotoGP, aiming for good performance but not pushing too much on performance

Dorna and IRTA used to pay Dunlop for its Moto2 and Moto3 tyres, which were given to teams for free, while Michelin gave its tyres for free. Is this how it will work with Pirelli?

This is a matter of contract, so I cannot comment.

Pirelli has a lot of championships to service – so how many race tyres will you produce each year?

When we started making tyres for World Superbike in 2004 [Pirelli was motorcycle racing’s first spec-tyre supplier, five years before MotoGP] we went from making a few hundred tyres, using special machinery and processes in a special department, to moving all the production to Germany, where we have standard production lines.

In the beginning this was a big restraint for us and for our engineers, but in the end we can say it’s the best move we could’ve made because now we are able to produce hundreds of thousands of slick tyres, which means we can control the process and the quality to make an affordable product.

You are in a kind of monopoly situation now, supplying tyres for all Dorna’s championships, so how can Dorna be sure you won’t take advantage?

It’s important that the promoter understands that having a tyre manufacturer as a partner is important, not only because you get a sponsor, but also because it helps you manage the championship in a certain way. So you have to trust in the tyre manufacturer and work with them in order to improve the championship.

This is what we’d like to have in MotoGP, as we have in World Superbikes – to be part of the show. It’s not a matter of power; it’s a matter of partnership.

When do you want to start testing and which riders will test the tyres? Presumably factory MotoGP test riders? And will you start with WSBK tyres and then go from there?

We would like to start as soon as possible. Now we are preparing tyre sizes for the [current] MotoGP rim sizes, so we can’t start with superbike tyres, which aren’t suitable for MotoGP bikes anyway, so we will put all our knowledge into this and then we will be ready to test.

Of course, we can’t ask the riders that are playing for the championship to be part of the first tests, so these tests will be with test riders, using MotoGP bikes. The question now is when will the 2027 bikes be ready and what can we do now? Because we need to start this season and not wait for 2026.

MotoGP test riders are going to be busy!

There are some manufacturers with concessions and others without, so some manufacturers will test more than others. And then we have to consider this: will some of the manufacturers still have concessions or will they all be on the same level? These are decisions that Dorna must take, then we will go ahead.

So you will obviously have to start with 1000cc bike?

Why not? But we cannot take this decision, so we have to wait.
