MotoGP rules changes for 2011
Time for a change? MotoGP digital tracking systems and qualifying/practice session times altered along with Moto2 and 125GP rulesLast minute changes to the MotoGP, Moto2 and 125GP rules have been enacted by the GP Commission, including modifications to GPS usage and Saturday practice and qualifying.
The GPS changes aren't likely to have a huge impact on data logging and remote chassis changes on the fly, but Dorna has stipulated that all premier class MotoGP teams use Dorna-supplied GPS systems.
Currently most teams spend big bucks on electronics, telemetry and tracking systems, which can help teams by plotting where the bike is on the track and adjusting engine and suspension systems to suit various corners and the like, and the new rule is designed to reduce the cost of racing in MotoGP.
Ultimately the GPS rule is not likely to have a huge impact on the current order, and the top teams will probably remain at the top.
Other changes to the rules include practice and qualifying sessions being raised from 45 minutes to 60 minutes in the premier MotoGP class. The Moto 2 and 125GP classes remain the same, with 45 minute sessions.
There's also changes to the grid positions and generators are now allowed for tyre warming before races. See below for the official spiel:
1
Two days for each class.
- MotoGP: 4 sessions of 60 minutes.
- Moto2: 4 sessions of 45 minutes.
- 125cc: 2 sessions of 45 minutes (morning) and 2 sessions of 30 minutes (afternoon).
2. Grid position for each class: 3 riders per row.
3. Generator for tyre warmers are permitted on the grid for the 3 classes.
4. In MotoGP, only the GPS provided by Dorna is permitted.
Rules are also being implemented for the Moto3 class that will replace 125GP in 2012, with all ECU's for the 250cc single-cylinder engines to be supplied by one company. Essentially all bikes will use the same ECU, in an effort to keep racing tight.
More light has been shed on the particulars of the 250cc engine too, with rev ceilings of up to 14,500rpm allowed. If such engines find their way into production 250cc engines... See below for the full details:
