Amazing how long that chain is. The swingarms seem to keep getting longer. Now if Yamaha can figure out the seamless transmission, we will have more parity.

I assume a "withdrawn" engine means an engine that is taken out of service due to a crash, mechanical problem or simply retired? I'd like to learn more about typical engine wear over race distances.

Here is an update to MotoGP engines after Qualifying 2 at Motegi. Data taken from official Dorna Engine Lists.Honda
Again, factory teams (Honda and Yamaha only) are limited to five engines for the season.

After Marc Marquez pulled off the track in FP3 on Saturday, you may have heard Livio Suppo from HRC say in response to Dylan Gray’s question about Marquez polling off track: “There was something wrong with the engine. The engine was working but with some strange thing… And because it was a new engine, Marc preferred to switch it off and come back to the garage to check.”

This turned out to be a non issue: Marquez and Pedrosa both started using their fifth engines in FP1 at Motegi. In spite of Marquez pulling off track in FP3, he used his new (fifth) engine in QP2. Pedrosa also used his fifth engine in QP2.

Bradl still has four engines in service with one withdrawn from allocation, and used engine #4 in QP2.

Bautista still has three engines in use with two withdrawn. He used engine #4 in QP1 and QP2.

Yamaha
Rossi still has five engines in service and used engine #3 in QP2.

Lorenzo has four engines running with one not yet in service. He used engine #4 in QP2.

Espargaro has four engines running with one not yet in service. He used engine #3 in QP2.

Smith has four engines running with one not yet in service. He used engine #3 in QP2.

Ducati
Ducati is allowed 12 engines instead of five and rider use is as follows.

Dovizioso’s sixth engine, #8, was withdrawn from allocation for the Japanese GP, so he began with three engines currently in use, with and still has three unopened.

Crutchlow’s fifth engine, #3, was withdrawn from allocation for the Japanese GP, so has two in use, and five unopened.

Hernandez has six engines in use and six unopened, having withdrawn none so far.

Iannone has had seven engines withdrawn, has four in use and one unopened.

Open Teams
Open teams also receive 12 engines this season.

Aleix Espargaro’s Forward Yamaha allocation shows four engines withdrawn, five opened, with three more waiting to be used.

His teammate, currently De Angelis, who inherited Colin Edwards’ allotment, shows five withdrawn, four in service and three unopened.

Hayden’s seventh engine, #7, was withdrawn for the Japanese GP. Engine #9 was sealed and brought into service, leaving two unopened.

Aoyama has lost eight so far, has two in service and two unopened.

Redding has withdrawn seven, has three in service and two unopened.

Abraham has withdrawn six, has three in use and three unopened.

The remaining riders’ allocations are as follows:
Barbera: five withdrawn, two in use, five unopened.
Di Meglio: five withdrawn, three in use, four unopened.
Laverty: seven withdrawn, four in use, one unopened.
Parkes: seven withdrawn, three in use, two unopened.
Petrucci: five withdrawn, three in use, four unopened.

Here is an update to MotoGP engines after Sunday Warm Up at Sepang. Data taken from official Dorna Engine Lists.


Honda
Again, factory teams (Honda and Yamaha only) are limited to five engines for the season.

Marquez used engines #4 and #5 over the weekend, racing engine #5. None has been withdrawn from allocation, though Marquez has not used engine #1 since Catalunya and #2 since Assen.

Pedrosa also used #4 and #5 from his allotment over the weekend, and also raced #5. He has not used engine #2 since Catalunya, and last used #1 at Indianapolis. He also no engines withdrawn from allocation.

Bradl still has four engines in service with one withdrawn from allocation, and used engine #5 for the race. Engine #2 was withdrawn at Assen, and he has not used #1 since Silverstone.

Bautista still has three engines in use with two withdrawn. He used engines #4 and #5 over the weekend, racing #5. Interestingly, Bautista has not used engine #1 since the race at Assen. While #1 has not been withdrawn from allocation, Bautista has been using #4 and #5 since Round 9 in Germany. That’s nine rounds on two engines.

Yamaha
Rossi still has five engines in service. Until Sunday he used #3 and #4. For Warm Up he used #4 and #5, then raced #5. Also with five engines in his allotment, he has not used #1 since FP2 at Indianapolis, and he has not used #2 since the race at Catalunya.

Lorenzo started using his fifth engine at Phillip Island. He used #3, #4 and #5 at Sepang, racing #5. The longest rest any of his engines has had is that of #1, which has not been used since Misano. He also has none removed from allocation.

Pol Espargaro saw his #1 engine withdrawn at Sepang, but he still has one engine yet to be used. He raced #3.

Smith has four engines running with one not yet in service. He raced engine #2.

Ducati
Ducati is allowed 12 engines instead of five and rider use is as follows.

Dovizioso now has six engines withdrawn and six in use. He hasn’t used #4 since Silverstone, and raced #12.

Crutchlow remains with five engines withdrawn from allocation. Having opened #9 for Warm up, he raced #8 and now has four in use with three unopened.

Hernandez has seven engines in use and five unopened, having withdrawn none so far. He raced #7. He has not used #1 since racing it at Assen, and he has not used #2 since Le mans.

Iannone opened #12 at Phillip Island for Warm up, and then raced it. For the first three sessions at Sepang he used #11 and #12 before withdrawing for the weekend. He now has seven withdrawn, five in use, none unopened.

Open Teams
Open teams also receive 12 engines this season.

Aleix Espargaro’s #10 engine was opened for FP1 at Sepang, and he raced that engine. He has four withdrawn, six in use, and two more waiting to be used.

His teammate, currently De Angelis, who inherited Colin Edwards’ allotment, shows five withdrawn, four in service and three unopened. He raced #9.

Hayden’s #9 engine was withdrawn after being used for Fp2, leaving seven withdrawn in total, two in use and two unopened. GP. Engine #9 was sealed and brought into service, leaving two unopened.

Aoyama has lost eight so far, has three in service and one unopened.

Redding has withdrawn seven, has four in service and one unopened.

Abraham has withdrawn six, has four in use and two unopened.

The remaining riders’ allocations are as follows:
Barbera: six withdrawn, two in use, four unopened.
Di Meglio: five withdrawn, four in use, three unopened.
Laverty: seven withdrawn, five in use.
Parkes: seven withdrawn, four in use, one unopened.
Petrucci: five withdrawn, four in use, three unopened.

Comparing engine usage in 2014
For those entering under the Factory Option banner (such as Repsol Honda Team and Movistar Yamaha MotoGP), the teams were subjected to new engine freeze regulations and the use of no more than five, sealed powerplants for the entirety of the season. On the other hand, Open entrants like Drive M7 Aspar were able to make use of up to 12 engines, which could be developed across the course of the campaign. Adding another variable into the mix, Ducati Team and Pramac Racing were granted special dispensation to run to Open regulations despite being Factory Option, having not won a race in fully dry conditions during the previous season.

Marc Marquez and Dani Pedrosa enjoyed a comfortable season, finishing the year on either their fourth or fifth engines which had progressed through barely half of their lifecycles; a remarkable feat bearing in mind that between them they racked up some 14,000 kilometres of running in practice sessions alone. Stressing how strict safety margins are to factor in any problems, neither LCR Honda MotoGP’s Stefan Bradl nor GO&FUN Honda Gresini’s Alvaro Bautista exceeded their five engine allocation despite each losing one engine from their allocation due to failures. For those racing Yamahas, engine life was certainly never a worry, with Jorge Lorenzo proving this with the fact that his fifth engine progressed through only a quarter of its working life.

Amongst the Open runners using the new Honda RCV1000R customer bike, Scott Redding (GO&FUN Honda Gresini) and Nicky Hayden (Drive M7 Aspar) went up to their 11th engine, while Hayden’s team-mate Hiroshi Aoyama was the only rider to use his maximum 12; this is perhaps reflected in the fact that the Japanese rider was the only representative on the grid to finish every one of the 18 Grands Prix this year, as well as having moved onto a 12th and final engine when he debuted the all-new 2015 customer Honda - the RC213V-RS - at the final event in Valencia. Top Open runner Aleix Espargaro (NGM Forward Racing) took only his ninth and tenth powerplants to the Ricardo Tormo circuit at Round 18; however, one of his engines had been damaged when he was hit by Stefan Bradl in Australia.

Things were arguably most complicated for the Ducati riders, as engines were swapped around as the different GP14, GP14.1 and GP14.2 models were raced during the season. Andrea Dovizioso exploited all twelve of the engines available to him, as did Andrea Iannone; old engines could not always be fitted when chassis were updated, as elements of the housing would need to be updated – contravening regulations. On the contrary, team-mate Cal Crutchlow received far fewer updates during the season and so would end the year on only his ninth powerplant.

Since MotoGP has such a big discrepancy in funding between teams (think HRC and PBM), this, along with different tire options and fuel capacities, is Dorna's attempt to level the playing field. Their attempts usually have no bearing on outcomes, though.

Lol, um, no, that would be the other Dave - CBR time. I love the sport, but I'm relatively new to MotoGP. It helps to have the video pass, though - I've been able to catch up on all the history since 92.

BTW, the off season Video Pass will be on sale for Black Friday for £.99. The sale starts Thursday and ends Friday night. If you haven't used the Video Pass, this is a cheap way to try it out.

While F1 rules and restrictions are incredibly severe, at least it makes for closer racing. The last few years of MotoGP have been fairly meh as money and robot riders are dictating the top 3 every single race.

Closer racing aside, weren't there only 3 winners in F1 this year? Rosberg, Hamilton, and Ricciardo, I believe. Racing is racing, and as long as there are no spending limits, no form of artificial handicap is going to matter. The best teams and riders are going to find ways around those handicaps. Unless you're Rossi on a Ducati - then the handicap of the bike itself can be too great.

We're never going to see all those guys racing against each other on the exact same bike - that can be seen as a good thing, or a bad thing, depending on your point of view, but Dorna is in the difficult position of trying to make money as well as field a competitive series.
