Corrado Cecchinelli On The Future Of MotoGP: Part 2 - The Hows And Whys Of Limiting Aerodynamics

By David Emmett | Sun, 05/Nov/2023 - 12:30

In part 1 of this interview with Corrado Cecchinelli, Dorna's Director of Technology, we talked about how his objective for the MotoGP rules package due to come in from the 2027 season was to improve the safety and increase the sustainability of MotoGP by looking at ways to limit performance without restricting the ability for engineers to explore innovative solutions too much, and to create an environment in which R&D in racing transfers more directly to road bikes.

The aim is to make the racing safer without forcing the tracks to make expensive, and sometimes impossible, safety upgrades, and to reduce the risk of crashing at excessively high speeds. The other important aim is to allow ordinary motorcyclists to benefit from the lessons learned by manufacturers in MotoGP.

Sepang MotoGP Test Photo Analysis: Aprilia's Wings, KTM's 3D Printing Advantage, And Yamaha Aero And Frame

By David Emmett | Fri, 10/Mar/2023 - 17:36

Aerodynamics was a main focus for most of the teams (and coincidentally, also the easiest thing to spot), and almost all the manufacturers rolled out some interesting parts. Aprilia have taken a leading role recently, picking up after Ducati and in some aspects, overtaking them. At Sepang, they rolled out a new front wing, pictured here (my phone photo) on Maverick Viñales' bike.

As you can see, the front wing now is now a triplane and not a biplane, with three wings instead of two. If you compare it with the photo of the standard front wing (below, picture by Cormac Ryan Meenan), you can see that the upper wing has been split in two to create something similar to the original, while an extra wing has been added below, curving up before reaching the fairing.

Sepang MotoGP Test Photo Analysis: Honda's 'Ground-Effect' Fairing - Was It Hiding Something More Significant?

By David Emmett | Mon, 06/Mar/2023 - 00:31

There was a great deal of excitement when this unusual prototype bike (my shoddy phone camera photo) was spotted in the Repsol Honda garage at the Sepang test. Was Honda the latest factory to try out a ground-effect fairing? The obvious answer was yes, but this misses the point entirely. This bike spoke volumes about what HRC was up to at Sepang. And it had very little to do with aerodynamics. Or at least, it had very little to do with ground effect.

The changes at HRC – former Suzuki engineer Ken Kawauchi replacing Takeo Yokoyama as Technical Director – have see Honda go back to basics. At Sepang, Honda sent Marc Marquez out to ride the Honda RC213V with just a plain fairing, no aerodynamic wings fitted at all. "The new technical manager arrived in HRC, and he wants to understand many things about the concept," Marquez explained. "I was not asking about why this, why that. I was just riding."

Look beyond the ground-effect fairing on the strange prototype, and this bike too looks more like HRC going back to basics. To understand what Honda are up to, let's go through a few photos and parts, one by one.

From Conflict To Collaboration: How The COVID-19 Crisis Reconciled The MSMA

By David Emmett | Tue, 12/May/2020 - 20:31

Once upon a time, the manufacturers reigned supreme in MotoGP. The MSMA – the Motorcycle Sports Manufacturers' Association – determined the shape of the premier class. In the early years after Dorna secured the rights to promote Grand Prix motorcycle racing, the MSMA negotiated a monopoly over the technical regulations in MotoGP.

The rules in MotoGP are made in committee, the Grand Prix Commission, containing representatives of the four parties with an interest in the sport: Dorna as promoter, the FIM as sanctioning body, IRTA representing the teams, and the MSMA on behalf of the manufacturers. While the sporting and other rules are voted on by majority, the MSMA controlled the technical rules.

In the early years of the MotoGP era Rule changes proposed unanimously by the MSMA were adopted automatically, and the MSMA retained a veto over rules put forward by the other members of the GPC. It was the MSMA who asked for the switch from two strokes to four strokes, and the MSMA who insisted on reducing the capacity from 990cc to 800cc in 2007, when concerns were raised over the speeds of the bigger bikes.

Qatar MotoGP Test Saturday Round Up: A Fast Yamaha, Ducati's Holeshot Squatter, And Aprilia Aggro

By David Emmett | Sun, 23/Feb/2020 - 01:21

If there is one thing that we learned from the Sepang test, it is that the field is even closer this year. In Malaysia, 18 riders finished within a second of one another. That pattern has continued at Qatar, Pol Espargaro in fourteenth just 0.987 second behind the fastest man, Alex Rins. As comparison, the KTM rider was the last rider within a second of the fastest man after the first day of this test in 2019, but then, there were just eight riders ahead of him, rather than thirteen. And there was a gap of nearly four tenths of a second between the riders in second and third last year. Not so in 2020.

But if the single lap times were close, the race pace was a lot less so. Maverick Viñales towered over the rest in terms of consistent pace, with only the Suzukis of Alex Rins and Joan Mir getting anywhere near the pace of the Monster Energy Yamaha rider. Viñales laid down a real benchmark, with ten of his 47 laps in the 1'54s, which is under the race lap record. That included a run of ten laps, seven of which were 1'54s, five of which were consecutive. That is a rather terrifying race pace for the Spaniard to lay down, just two weeks ahead of the first race.

Tom's Tech Treasures: A Look Back To The 2019 Valencia Test

By David Emmett | Wed, 05/Feb/2020 - 10:16


Honda RC213V 2020 prototype (Marc Marquez)
David Emmett: You can tell this bike belongs to Marc Márquez by looking at the rear brake disc. The ventilated disc is a sign that it gets heavy use, and needs a lot of cooling.
This was one of the prototypes used by Márquez at Valencia, but the chassis is a tell that this was just being used to test the new engine. The frame still has the engine mount spar above the clutch (the section the fairing is attached to, by the bolt just behind the R of Repsol). At Valencia and Jerez, Márquez tested a chassis without that bolt, giving the frame a little more flex.

HRC Bosses Kuwata & Wakabayashi Interview, Part 2: On Swingarm Spoilers, Jorge Lorenzo, And Winning It All

By Akira Nishimura | Tue, 04/Feb/2020 - 16:01

In part two of our exclusive interview with Tetsuhiro Kuwata, HRC general manager of Race Operations Management Division, and Shinya Wakabayashi, general manager of Technology Development Division, address the aerodynamic innovations introduced by Ducati at the Qatar MotoGP race in 2019, and the possible effects that can have. They also talked about the challenges of balancing the performance of Marc Márquez with trying to help Jorge Lorenzo to succeed. The HRC bosses also discussed the input Lorenzo had on the development process, and how it was affected by his decision to retire. That leads on to a discussion of what to expect for 2020, for Alex Márquez, alongside brother Marc in the Repsol Honda squad, and for Cal Crutchlow and Takaaki Nakagami in the LCR Honda team.

Q: At the season opener in Qatar, Ducati introduced a swingarm attachment, the so-called “spoon” or swingarm spoiler, and it caused controversy among the manufacturers. Anyway, the fact is that they are very smart in finding loopholes in the regulations. Does HRC read the rule book meticulously like them in order to find something which hasn't been specifically prohibited?

Kuwata: Maybe you can take an approach to check if your good idea infringes on the regulations. And you can also take another approach from the opposite direction, but it makes no sense if you don’t have any objective with that loophole. If you have ten ideas and read the rule book carefully to check how many of them are legal, it will be a persuasive approach. I am guessing maybe Ducati is taking this type of approach. Probably, loopholes don’t come first, but I don’t know.

Q: Does the attachment have an aerodynamic effect?

Kuwata: I guess so, that’s why everyone uses it.

2010 – 2019: MotoGP's Long Decade Of Change, And What It Means For The Future

By David Emmett | Thu, 09/Jan/2020 - 12:58

2020 sees the start of a new decade (convention has it that decades are zero-based, going from 0-9, so please, numerical pedants, just play along here), and if there is one thing we have learned from the period between 2010 and 2019, it is that a lot can change. Not just politically and socially, but in racing too. So now seems a good time to take a look back at the start of the previous decade, and ponder what lessons might be learned for the decade to come.

It is hard to remember just how tough a place MotoGP was in 2010. The world was still reeling from the impact of the Global Financial Crisis caused when the banking system collapsed at the end of 2008. That led to a shrinking grid, with Kawasaki pulling out at the end of 2008 (though the Japanese factory was forced to continue for one more season under the Hayate banner, with one rider, Marco Melandri), and emergency measures aimed at cutting costs.

The bikes entered in the 2010 MotoGP season

Tom's Tech Treasures: Yamaha's New Exhaust And Swingarm, Aprilia's Holeshot Device

By David Emmett | Tue, 01/Oct/2019 - 11:03


Rear wheel cover on the GP19 and carbon swingarm.
David Emmett: The full set of rear aerodynamics on the Ducati Desmosedici GP19, from the swingarm spoiler to the rear wheel covers. The rear wheel cover mounting points are clearly visible: at the rear of the chain tensioner, and at the front below the aluminum bracket with holes. The rear swingarm spoiler caused huge controversy at the start of the year, and now all manufacturers bar KTM have one.
Ducati used a loophole in the regulations to use the swingarm spoiler and wheel covers, but this loophole will be closed for 2020. For next season, all parts which are not part of the structural part of the motorcycle will be classified as part of the aero body, and so their designs will have to be homologated, with one update allowed during the season. So Ducati can start the season with one spoiler, and alter it once during the year.


Lighter front mudguard on the KTM RC16.
Peter Bom: Although it is a little bit difficult to see in this photo, the mudguard ends immediately after the double L of Bull. This leaves more of the front tire exposed, helping it to run a little cooler and prevent overheating. Some KTM riders have complained of this previously.
