MotoGP to 1000cc in 2012

what makes me laugh Vtec is banned its such a great system i have a Vtec car and love the power it makes you have torque down low and just full on power up high and love the kick back feel you get when the Vtec opens up, Moto 2 has banned this dumb!


The engines will be based on original motox engines like the RS once was but then it will develop over time and I dont think holding onto 1 make brands sealed engines is a good idea I hate it, At this level especially GP its about the team and rider being able to all bring together one good package not everyone on the same engine no work aloud

It was. It's now about the MotoGP brand. Get used to it. They'll still be knife-edge mofos to ride.

MotoGP faces a real problem. Their ONLY star is Rossi. when he retires the racing better be damn close or people will switch off in droves. They will anyway, but if the racing is good, then it will lessen the impact of Rossi leaving. Their only other hope is if Simoncelli and Lorenzo can increase their fruitiness factor to the point where the general media notice.

Hmm, if bore size is 81 mm, maximum number of cylinders is 4, so stroke is ...... 48.5 mm, implying a bore/stroke ratio of 1.67, which I think is not all that high by modern standards.

Oh never mind, Kropotkin has said it all already

I think it's a good thing for the factories to develop...but I'd rather see them develop it on production based bikes...not out and out racers!

The owners of the rights to World Superbikes have already fired a legal shot across the bows of Dorna. Can't remember the exact wording but it was to the effect that any attempt to create a MotoGP formula involving "production" engines would be met with an immediate legal challenge. Superbikes, Suoersport, etc being the racing classes for production based machines.

That KTM RC4 looks a delightful little confection. A 450 single cylinder racing bike might sound odd at first but there was a time when single cylinder engines weren't just heard on trail rides.

To replace the 125 class with moto cross engined bikes of 250, or 450, or whatever, might make a good cost effective option. As long as they can avoid the use of that word "production":....

Interesting but it's hard to see how someone can claim the legal rights to any form of racing, production based or not. Unless it's a breach of an agreement between WSB and MotoGP organisers?

I'm sure the lawyers will be pleased to represent the various factions.
For a fee. The threat was discussed by the commentators during the running of one of this years SBK rounds.

The two MotoX engined KTM machines featured in BIKE were in all other respects pukka GP bikes. The 450 had been shoehorned into a 250 GP frame and running gear, the 250 into a 125 GP frame. They both looked the part. These bikes were apparently an exercise conducted at the request of the KTM CEO.

At least one overseas board has been discussing the bikes on the assumption that the RC4 was to be a road bike. There have previously been pictures of a sportbike using one of the bigger KTM singles. The examples BIKE rode were out & out racers though.

The Harris WCM Would be Legal:

As to why the Harris WCM was rejected in 2003 until the crankcases had been replaced with prototype cases, Ezpeleta argues that that call was made on the basis of the rules as they were written at that time, rules that have since been changed. It is his contention that the WCM as originally presented to scrutineers at the start of the 2003 season would be legal under the rules that will go into effect in 2012.

Ezpeleta has said that nothing in FIM rules or traditions requires an engine powering a prototype racing motorcycle to be a prototype.
