250 GP'S to become 600cc gp2....

[castrolcraig]

well its officially going to be announced at 12.15pm on saturday at le mans gp, so from 2010 instead of the legendary stinkwheels we will be seeing baby screamers............


im drooling at the thought already.

[y2blade]

about time too

[kingb]

i think thats a shame

they have a 600cc catagory is called supersports!!
i think the 250s are great beacuse of the corner speed they carry with their lightweight

plus i guess they will be 4 strokes? bring back the shouty 2 stokes

i think it should stay put

[R5GTTgaz]

A sad day to see the two stroke go.

[telecat]

In off road sport there are already moves for all Two Stroke Venues. Too many of the 4T's are just too loud and land was being lost.

[tim2100]

this is a good thing, no 250's are sold anymore so a 600 class will have a better reflection on the market

[castrolcraig]

on the other hand guys, realise that know all the brits in 4 stroke catergorys especially rea, jones, gowland etc will have an easier route into motogp through motogp2...

although i will be sad to see the stinwheels with that aroma of castrol go the 4 stroke era is here and it makes more sense to have a "feeder" class more relevant to the big class.....

now, what to do with 125's........

[R5GTTgaz]

I suppose it will give lesser skilled riders to have a chance in the top series.

How do you make that out ?

Yep spot on mate, there has been talk of this for quite a while. Gilera and Aprilla will pull out of the series thats what stopped DORNA from doing it thus far.

More traction control bikes on the scene naff! Supersports is in WSB we don't need anymore. Ridng the mountain section last year on an RGV 250 was the most fun i've had in years!

[FeatherZ]

125's will be around for a long long time, its great at bringing talent forward, 4 stroke 125/250 is not an option really, maybe a 450 single 4 stroke may be the future but 125's are gonna be around for the next 5-10 years at gp level id of thought.

hmmmmm, maybe you dont understand, full prototype 600cc bikes with very little development cap, and NO ELECTRONIC RIDER AIDS.

yep, the the leser skilled riders will have a chance, to compete for the best highside of the year............

Wow about time but sure its 600cc? On full prototypes thats pretty close to the Full Monty and probably not far off WSB pace.

400cc seems more than enough to get the power of 250cc strokers (~110bhp?)

Now just get the 125's to 200cc twins/fours and job done.

i thought 250s were making a comeback? didnt kwak bring out a 250 ninja recently to meet the 33bhp licence?

250 2 strokes 110bhp??

try 146bhp atw for a 2008 aprillia 250 stinkwheel....

yep im sure its 600cc, im quite in the now, you now....;)

So why didnt the NSR500 put out nearly 300bhp?

110bhp is more on the money.

mate you have to realise that technology has moved on lots since the death of the 500 2 stroke rip snorters, and much smaller engines are capable of greater power, not too mention the advances in fuel, the atol regulation fuel is really realy good...

[Dave D]

Yep some confirmation of the changes now, proposal is for 625/650cc four cylinders.

http://www.motorcyclenews.com/MCN/sport/sportresul...

Considering the way 800cc lived up to 990cc lap times its difficult to see a 650cc rule existing for long before at least embarrassing the MotoGP class. Four pots also makes for a close run thing as even if 250's were 146bhp this will surely be a step up to circa 180bhp. Still its going to be a good show.

146bhp??? were do them figures come from?

imo that is way off the mark, the rumoured power is 100 to 105 max

google said:

Randy De Puniet / Sylvain Guintoli
Bike : Aprilia RS 250 GP 2001
Power : 94 Hp at 12500 rpm
Brakes : 2 Brembo radial calipers, disc Ø 255 mm and carbon/carbon brakes pads, Carbone Lorraine
Weight : 95 kg

Them figures are from seven years ago, but two strokes have been near the limit of development for the past two decades, they may have found 5 - 10 % peak bhp, but 50% i don't think so!

Has it been confirmed that there will be no electronic rider aids? Can't see how they will police this. A 600cc four prototype will develop enough power (and be peaky enough) to warrant the electronic aids getting rolled out. Ultimately they will become a mini motogp bike. Unless they go down the homologation ECU route then these things will have traction control, launch control, wheelie control....
