Moto2 engines to be based on CBR600RR

Dailies -


Honda_Moto2_engine.jpgThe engines Honda will supply to the 250GP-replacing Moto2 class will be based on that of the current CBR600RR. Despite their humble basis, the motors will produce over 150bhp and will be capped to a 16,500rpm redline. Honda has apparently been developing this engine for over two years, we’d guess since it first informed Dorna that it should replace two-strokes with four-stroke inline-fours.
Dorna will purchase each engine from Honda, then sell them on to the
individual teams. The idea there is that Honda won’t know which team is
getting which engine, so can’t drop a few bolts in the cylinders or

The engines will use a wet clutch, strangely won’t use a cassette
gearbox, come with a spec ECU and airbox and have a service life of at
least 2000km. That last thing means that teams will only need three
engines per bike, per season notwithstanding accidents. Noise levels
will be capped at 115dB.

Dorna is even in talks with Repsol to discuss the Spanish oil company
providing a spec fuel and there’s rumor of a MotoGP-like single tire

The cutoff for teams to register for the 2010 Moto2 season is this
Friday. In the near future all participating teams will receive CAD
drawings of the engines so they can develop their own chassis around
it. Honestly, every time we hear something new about Moto2 we just get
more depressed.

    I don’t follow the lower GP classes very closely–but if they’re based off of 250cc 2 strokes, isn’t the implication that they’re not new-tech test platforms? This seems to suggest that the class is a training ground for the top flight. So what is the problem with mandating contemporary engine technology? I suppose it is the death of a certain kind of racing, but I don’t think that any consternation over the loss sportmanship and skill is founded.

    i have to admit, even thou i’m a big fan of the GP class, but WSBK is simply more exciting to watch for a couple of seasons now.

  • aoelus

    Can’t get all weepy over the death of the 250cc class, tho I do regret Aprilia losing out on the biz, I assume they could have used it. Checking the teams web pages they all run the stock Aprilia
    racer, completo. Now the chassis will HAVE to be prototypes so gear heads can salivate over all the ingenious innovations. hehheh.

  • Scott

    WSS is the most exciting racing at the moment.
    GP needs to get rid of the electronics & bring back the slides & highsides.

  • blankfocus

    The 250cc class has definitely just become a pure feeder system for GP. So I’d have to agree that all the spec stuff probably isn’t that big a deal.

    On another note:
    WSBK has been awesome this year.

    I’m with you on this one Wes. We’re going from super-light, super-efficient 2 strokes (no, I’m not talking about emissions) to a glorified CBR600RR. What’s the point?

    Honda was a big reason for the end of 2 stroke 250 GP racing, they didn’t want to develop the engines. It’s always brought back to emissions but there are 2 stroke watercraft motors out there which meet emissions requirements. It can be done, they just don’t want to.

    I 2 stroke race motor is easier and cheaper to run than an equivalent 4 stroke motor. Fewer moving parts, easier to maintain and better power to weight.

    Moto2 stinks of boring, I just hope that the chassis they create allow the racers to ride like they already do or we might as well just go WSS racing.

    In my opinion it is a complete and utter farce.
    That two strokes in their current form are more polluting emisions wise is an important point. However, as has previously been stated, new development has seen the match or even exceed emission levels of four strokes.
    I can except the issue of costs, to lease an Aprilia RSA 250 (the only way to be competitive) is close to a million euros a season, getting close to sattelite moto gp territory.
    My dissappointment lies in the fact that with every press release about moto2 regulations, these bikes get dumber and dumber.
    Yes, the new bikes will teach riders about four stroke engine characteristics, but they will not learn a myriad of other set-up skills currently taught by the 250s.
    In 125s, you learn how to overtake (5 times a lap), in 250s you learn the intracacies of suspension, gearing etc.
    A lot of that sounds like it will be lost.
    The fact that the deal went to honda (whose hatred of 2 strokes is well documented) smacks of a underhand deal done a long time ago, with the “tendering process” just a pantomime.

  • Patrick

    How are the intricacies of chassis setup lost with the switch to 4 strokes? Wouldn’t the different setups required (for heavier bikes with different cornering characteristics) be more relevant to the 4 stroke premier classes like GP and WSB?

  • monkeyfumi

    The loss of choice in gearing was what I primarily meant.
    Gearing is a great skill in the lower classes, 125s will change ratios to find an extra 2mph.
    Individual styles might take a different ratio through a corner, which has an effect on their suspension setup for that corner.
    Another potential skill lost (remember, this is the class where skills are learnt for moto gp).
    It irks me that “pinnacle” gp racing bikes won’t even have technology found on 20 year old road bikes (cassette gearboxes).
    Racing is about competition, both mechanically and humanly. A spec engine takes away a large chunk of that, in my view, to it’s detriment.

  • Doug

    Instead of upgrading the Moto2 class to GP standards, they downgrade the GP to that of the 600 based street bikes. Does this sound like a retail marketing ploy ? “Buy our 600cc bike and you too can pretend to ride a GP bike” Old man Honda must be rolling in his grave alongside his
    5 cyl 125cc.

      A lucid man…with you 100%…respect!

  • monkeyfumi

    Exactly, if I wanted to watch road bikes, I’d watch supersport races.

    Wow, welcome to yesterday. Way to be on top of breaking news from two weeks ago.


    Oh yeah, there’s no single tire rule either, Michelin and Dunlop will be providing hoops. I guess we’ll all be reading about that in a few weeks. Can’t wait til amateur blogging dies a horrible death.

  • LADucSP

    it’s so funny how wrong we all were! the bikes are awesome, and the racing’s been incredible.

    the best part is that, when you take the motor out of the equation, all the development goes into the chassis!

    and that will have a major impact on the performance and safety of the bikes we ride.

  • Wilkinson Sword

    It’s just not the same having a single motor, don’t like it
