MotoGP Rules Updated: Fuel Limits, Concussion Tests, Etc

Google+ Pinterest LinkedIn Tumblr

The meeting of the Grand Prix Commission, held on Tuesday in Madrid, made a number of minor changes to the rules for all three Grand Prix classes, as well as a couple of more significant revisions.

The biggest changes concerned the setting of the maximum fuel allocation from 2016 at 22 liters, and the adoption of the SCAT3 test for concussion for riders after a crash. But perhaps the most significant outcome of the meeting of the GPC is not what was decided, but what was not.

Of the various minor rule changes, a few are worthy of comment. The first is the reduction of the time penalty at the start for a rider exceeding the engine allocation in any given year.

From 2015, anyone using an extra engine will start the race from pit lane 5 seconds after the green light is displayed after the official start (once all riders on the grid have passed pit lane exit), rather than 10 seconds.

This will have little direct impact on the outcome of any races, but should make it easier for riders using an extra engine to get close to the backmarkers, and perhaps score a point or two.

In the Moto2 class, tire pressure sensors will now be compulsory, to ensure that tire pressures are kept within the range set by the single tire supplier.

This is to enforce a rule brought in at the end of last year, when various Moto2 teams were found to be running dangerously low rear tire pressures in an attempt to improve rear edge grip and feel from the tire.

Making tire pressure sensors compulsory suggests that some teams had been flouting the mandatory tire pressure ranges, banking on not being caught.

In MotoGP, a maximum price has been set for a brake package, with €70,000 now the maximum brake suppliers can charge for a full season of dry weather racing (or €60,000 without brake calipers).

Unfortunately, the decision appears to leave some worrying loopholes open, with prices being set for dry weather packages only, and offering the possibility of ordering a package without calipers.

The last set of rules published in November mention that components will be subject to homologation and price controls. It is not clear whether this is still the case or not, and only once the full 2015 rule set is published will we find out.

The two most significant changes were the adoption of the SCAT3 concussion testand setting the fuel limit from 2016 at 22 liters. The adoption of a formal test for concussion is an important step forward for both rider safety, and for consistency of medical rulings.

There is a common complaint among riders that the decisions on whether a rider is fit to race can vary greatly between medical officers at race tracks, with some proving exceptionally lenient, while others are far stricter. The issue of concussion is a particularly difficult one in motorcycle racing.

If decision making is impaired due to a concussion which has gone undiagnosed, it could have very serious, and possibly even fatal consequences for both the rider concerned and others on the track in their vicinity. The SCAT3 test is a start, though it is far from perfect.

Some types of injury are particularly prevalent in motorcycle racing, and can create extra problems in assessing concussion via SCAT tests.

The regulations make no mention of baseline testing – a test performed prior to the season to establish the typical responses to SCAT assessment questions from each individual rider – which could be of assistance in ascertaining the extent of concussion.

However, baseline testing may not be needed, as the aim of using SCAT3 is to rule a rider unfit, not to test whether they are fit to race again after having been forced to sit out events.

Setting the fuel limit at 22 liters for 2016, when MotoGP becomes a single class again and spec electronics are adopted for all MotoGP machines, is just about expected.

The current Open bikes, as well as Ducati, all run between 21 and 23 liters, depending on the track concerned. Honda had been pushing for a lower limit, but the other factories were keen to keep more fuel. With spec electronics, 22 liters is a realistic amount to use.

More significant than agreement on the fuel limit is the lack of agreement elsewhere. Agreement on the number of engines per season, and the minimum weights for MotoGP bikes have both been pushed back to February.

It was widely feared in Dorna and IRTA that such a move could happen, as the longer such decisions are delayed, the less time there is to make the changes needed to prepare for next season.

That, in turn, could be used by some factories to make a case for making no changes to the rules, leaving the maximum engines at five per season. Though that may save costs for existing factories, it would make it virtually impossible for new factories to join MotoGP, and to be competitive.

A significant omission from the proposed rules is the lack of a rev limit. This now looks unlikely to happen until the next full overhaul of the regulations in 2021. A rev limit would be a significant tool in reducing top speeds, but the factories – especially Honda and Ducati – were vehemently opposed.

The new regulations also provide evidence that Dorna feel they are fighting a rearguard action against the factories. The banning of “additional devices” between the ECU and actuators is one loophole which has been actively pursued with spec electronics packages in Moto2 and Moto3, and could have caused major problems in MotoGP.

The best-known example was the special quickshifter strategy adopted by several Moto2 teams in 2012, most notably by Marc Marquez. That required adding an extra component in the quickshifter circuit, to improve acceleration and shorten the duration of the ignition cut.

Adding extra components between ECU and actuators such as throttle butterflies, injectors or ignition could offer better control than the spec electronics allow, and undermine the push to standard electronics.

It is, however, typical of the arms race which continues between rule makers and teams. Factories and teams are always on the lookout for an advantage, and seeking the gaps left by the rulebook.

As the rulebook expands, so the opportunity to exploit such loopholes expands with it. Like tax law, the thicker the rulebook, the more opportunities there are to work around it, to which the usual response is to add yet more rules.

Below is the full text of the press release on new regulations:


FIM Road Racing World Championship Grand Prix
Decision of the Grand Prix Commission

The Grand Prix Commission, composed of Messrs. Carmelo Ezpeleta (Dorna, Chairman), Ignacio Verneda (FIM CEO), Herve Poncharal (IRTA) and Takanao Tsubouchi (MSMA) in the presence of Javier Alonso (Dorna) and Mike Trimby (IRTA, Secretary of the meeting), in a meeting held on 16 December in Madrid (ESP), made the following decisions:

Sporting Regulations

Effective 2015

Changes to the Sporting Regulations mainly involved incorporating into the Grand Prix regulations protocols and procedures that had already been defined and implemented during the 2014 season. These matters included:

The procedure to be adopted when there is a change in climatic conditions after the riders have reached the grid after their sighting lap.

Changes to the defined position of the pit lane exit and the introduction of a line painted on the track which must not be crossed by riders exiting pit lane.

Procedures and bike positioning for change of bikes in MotoGP class flag to flag races.

New regulations approved were:

  • Consequent on the pit lane exit changes, when serving a penalty for excess engine use, riders starting the race from pit lane will start five seconds after the display of the green light at pit lane exit, rather than the current ten seconds.
  • Small changes to the regulations concerning warning flags were made to bring these into line with regulations in other FIM Championships.

Technical Regulations

Effective 2015

Moto2 Class

The use of tyre pressure sensors, measuring the pressure of a slick rear tyre, is compulsory. This will enable the Technical Director to enforce existing regulations that require riders to use the pressures approved by the official supplier.

MotoGP Class

The maximum prices that may be charged for the supply of brake packages normally sufficient for a complete front wheel, dry weather season, were confirmed. The full package, including discs, pads, calipers and master cylinders, may cost no more than €70,000. Teams may choose to have a package that does not include calipers and the maximum price for this is €60,000.

It was already announced that Factory teams in the MotoGP class must move to using unified software with effect from 01 July 2015. It has now been confirmed that different teams, using machines from the same Factory, may use different versions of the unified software.

All Classes

It is already a regulation that the lower portion of bodywork must have the capacity to catch oil or coolants in the event of an engine failure. It has now been agreed that the minimum capacity of these reservoirs must be 5 litres for Moto2 and MotoGP class machines and 3.5 litres for Moto3 class machines. The procedure for measuring capacity was also confirmed.

In the Moto3, Moto2 and MotoGP Open classes it is not permitted to use additional devices to modify the signal sent from the Championship supplied ECU to the actuators.

Effective 2016

Discussions continue in the Grand Prix Commission about the Technical Regulations for the MotoGP class from 2016. It is anticipated that matters like the number of engines to be available for the season and the minimum weights of machines will be finalised and announced early in February 2015. In the meantime the maximum fuel capacity for 2016 has been confirmed as 22 litres.

Disciplinary Regulations

Effective 2015

It was decided that it is no longer necessary to hold a hearing between Race Direction and the rider before imposing a minor penalty. Minor penalties are defined as the imposition of up to three penalty points, a fine of up to €1,000 or a grid penalty of up to three places. Naturally, riders retain the right to appeal against any such penalty in which case a hearing would be convened.

Medical Code

Effective 2015

It was agreed to incorporate into the regulations the new version of SCAT3. This is the Sport Concussion Assessment Tool which is already used by a large number of sporting bodies to evaluate injured athletes for concussion.

A regularly updated version of the FIM Grand Prix Regulations which contains the detailed text of the regulation changes may be viewed shortly on the FIM’s website.
