Moto GP is the equivalent to Formula 1 for motorbikes.From 2012 Moto GP switches back to 1000 cc bikes from the previous 800 cc racing bikes.The Moto GP bikes are purpose built and are not road legal so they are not offered for public sale.However super bikes from manufacturers Honda,Yamaha,Ducati try to incorporate some of the Moto GP technology for an affordable price for general public.The perfect Moto GP replica bike is the Ducati Desmosedici RR.So switching of Moto GP back to 1000 cc class could ensure some special motorcycles and the technology can be incorporated into the 1000 cc super bike counter part from the manufacturers. The rules for the new 2012 Moto GP feature a lots of changes in the rules after switching to the 1000 cc.The Governing bodies of Moto GP Fédération Internationale de Motocyclisme(FIM),IRTA (International Road-Racing Teams Association),Dorna along with the MSMA (Motorcycle Sports Manufacturers’ Association) which takes care of constructors in the Moto GP forms a Grand prix commission sets the rules for Moto GP race.According to the Grand Prix commission the changes to the 2012 edition of Moto GP are as follows
Starting with an overview of the Motor bikes used in Moto GP.
Moto GP bikes design differ from manufacturer to manufacturer and there are four Manufacturers in Moto GP they are Honda,Ducati,Yamaha and Suzuki these manufacturers combined with CRT (claiming rule team) will supply engines to the teams in Moto GP and they build a custom body for the engine.And some teams use the Bikes manufactured by the manufacturer and make some changes to the bike according to their needs like changing compression ratio,clutch system etc based on their analysing of previous performance data.The Moto GP bikes does not have headlight,horn,side stand they use paddock stand.Ducati has a road legal replica of their Moto GP bike Ducati Desmosedici and it is the Ducati Desmosedici RR
The four Moto GP manufacturer factory team bikes used in 2011 Moto GP along with the best riders on the bikes in 2011 season are mentioned below.
The engine is restricted to 1000 cc four stroke but the manufacturers have the choice of choosing the type of cylinder configuration for their bikes or like V-twin or V-4 or inline-4 but the maximum cylinders must not exceed four as more cylinder means more power for the same displacement so the rule of maximum four cylinders was imposed.The bikes have DOHC (Dual Over Head Camshafts) and 4 valves per cylinder.The bikes has a single water pump and the Moto GP bike engine revs up to 18000 rpm.The bikes use unleaded 100 octane fuel and the fuel delivery is by fuel injection.The maximum allowed power output is 240 bhp and the engine must be naturally aspirating engine (No turbo charged or super charged engines are allowed).The bike can attain a top speed of 349 km/h.A team can use only six engines for each contracted rider for one season.If they cross the limit for the engines the rider gets a 10 sec penalty when starting from the pit stop.The fuel tank is limited to 21 litres of fuel.
From 2008 Bridgestone was the sole tyre supplier for Moto GP.The compounds used in MotoGP are combinations of synthetic material and naturally sourced rubber which is vulcanised and transformed into latex. A typical race tyre comprises rubber, high tech plastic fibres, resins and minerals, combined to produce the highest level of performance.These tyres are not suited for road use as they worn out very easily because they are made for maximum grip on the race track.The choice for choosing the tyres is available to the rider and the team and they choose the compounds based on the track conditions,weather conditions and input from the rider and previous experiences and however the number of tyres and compounds used by a rider is restricted.during a wet race special wet tyres are used and these tyres worn out quickly if the track dried out.
The bikes use Carbon disc brakes.The application of carbon disc brakes to road bikes is very uncommon as very high temperatures are required for the carbon disc brakes to function.And also carbon disc brakes are very expensive a single set of carbon brakes can be at a cost of several thousand euros.The manufacturers of Moto GP disc brakes are Brembo and Nisssin.But if the weather is wet steel disc brakes are used as in wet condition it is impossible to attain the high temperatures required for the carbon disc brakes to function.There is no restriction of number of brakes available per season.
At the Track:
Now coming to the track rules there are many places on a track where the regulations vary they will be described elaborately.
A workshop or garage in which each team prepares for the practices, qualifying sessions and races. Pit-boxes contain monitoring equipment, tools, spare parts, tyres, replacement bikes and of course several busy team members.The team members analyse the corner speeds distance from other riders and lap times and number of laps completed etc. When the bike comes to the pit boxes they are filled with fuel and they check for air pressures in the tyres and also replace the tyres if the tyre is worn out.They check for fluids in the bike.And ensures that the bike is in condition when it leaves the pit-boxes in the least possible amount of time.It is like a servicing done to a normal road bike where one would check for tyre air pressures and check the fluids in the bike and check whether everything is going on smoothly but it is done too fast on the race circuit as time is the most important factor in Moto GP as the difference between the winner and the runner up is only a very slight margin.One more important thing done in the pit-boxes is discussing the strategy for the remaining laps by the rider with the team members.The maximum number of team personnel per rider in the working area in front of the pits is limited to eight for MotoGP.The back doors of the pit-boxes lead to the paddock where the teams’ supply trucks are stationed, while the front of the pit-boxes leads directly onto pit lane.
The pit lane links the pit-boxes to the track itself and is close to the start/finish straight, from which it is separated by the pit wall.The pit lane is very crucial for riders to leave and return to their pit-boxes.For safety reasons riders are not permitted to travel at more than 60 miles per hour in this area of the circuit and the traffic is only one way in the pit lane .Any rider who exceeds the pit lane speed limit during a race will be penalised with a ride through and in the case of a second infraction of this speed limit, the black flag signifying disqualification will be shown to the rider with the riders number that means he must stop at the pits at the end of current lap and cannot restart.The pit lane is overlooked by the media and also by race control facilities and usually by a main grandstand.The riders exit from the end of pit lane and lap the track in order to get back to their starting positions.As we already mentioned above if the team crosses the six engine limit they have to start the race from pit lane 10 seconds after the race have started.In 2011 Moto GP legend Valentino Rossi had started the race with a 10 sec penalty at the Aragon Grand prix for crossing the six engine limit.
Team members can cross the pit lane from their garages to stand next to the pit wall, in order to pass on messages to the riders using their pit boards. As the riders come along the start/finish straight they look for their team members, who via the pit board can relay messages such as time differences between riders, numbers of laps completed, lap times or instructions to return to the pits during practice and qualifying and also in the case of a ride through penalty and disqualification if the rider does not observe the ride through penalty or disqualification respectively.To prevent over crowding only six crew members from each team are permitted on the pit wall at any given time during the race.
Adjacent to the pit lane and overlooked by the media facilities, race control and the main grandstand is the start/finish straight, where races commence and conclude. On the start/finish straight a grid is marked out for the riders instructing them where they will start the race. Of course there is also a finishing line marshalled by a race official, who displays the chequered flag as the riders finish the race.
This is a enclosed area located in the pit lane where the podium finishers (first three) in each race are guided after the action concludes on track. Here selected media are given first access to the riders – mainly for live television interviews – immediately after they have secured their podium finishes.They will be awarded with the prize for winning the Grand prix.
The paddock is located behind the main circuit complex adjacent to the pits and is the storage and work area for the majority of people who are involved in Grands Prix. As such it normally hosts:
- – The teams’ service trucks which contain various type of equipment’s and spare parts along with spare bikes are carried.These trucks contain all the equipment required in a Pit box/garage.
- – Media trucks containing offices and live broadcasting units with editing studios for the attending media
- – Hospitality units (teams, organisers and sponsors have hospitality facilities in which staff and guests can relax and dine at each Grand Prix)
- – Motorhomes this is the place where the riders rest,sleep and prepare for races
- – Administration offices of Dorna & IRTA where the administration and organizing of each Grand Prix is co-ordinated.
- – Tyre suppliers’ fitting areas.As one tyre supplier rule is followed Bridgestone is the sole supplier of tyres for Moto GP they have their supply trucks and work spaces where they prepare the compounds for each of the Moto GP teams based on the team specifications.
- -Although each circuit has its own permanent medical facility Clinica Mobile the official Moto GP mobile hospital is always present in the paddock.
