Anyone got any news on any of the new bikes, or know what kinda power they'll be putting out? I assumed they'd be less powerful, meaning current circuit records etc would stick around for ages, but I hear they're already putting out the same power.

Enlighten me Cool

Dont know if i heard right but i believe nicky hayden was racing his one today at mugello.

Allegedly they will only be a little bit slower so it should be similar but different if you know what i mean.

Word around the paddock is that they just rev higher, produce the same power, and are lighter than their current counterparts. The bikes should be even faster I reckon.

Going to be beneficial for the smaller riders/riders coming from 250cc as the bikes should be lighter and maybe smaller ?

A small comment in bike mentioned the new Ducati 800 matching the Kawasaki MotoGP bike in a straight line around Mugello. Apparently they're going to be more like a 250 to ride - which equates to higher corner speed - if they're already matching some current 990s on straight line speed, it's inevitable that lap times will continue to decrease.

I reckon money, or more importantly how much each team has will play an even bigger part in the new championship - as the bikes become more and more difficult to ride more technology would be needed so the rider can utilise such performance.

Would the new class revitalise the 750cc road bike market?

I see no point in the litre class. Less maneouverability than a 750, and 750s have a better power/weight ratio, and are cheaper. Makes no sense :S

I think Nicky Hayden was riding one on the last GP in Italy and he was 3rd. Not 100% it was him but one of the front runners was definately on one. Thumbs Up

I think you're way off the mark there. These machines are still heavily in development, to say someone was riding one in a race against the 1000cc machines is utter bull.

Who do you think was riding one then?

Rossi? No way
Capirossi? No
Hayden? No
Pedrosa? No
Gibernau?No

Who was the front runner "definately" riding one?

Nicky Haden was riding the 800 frame with the 1000cc motor in it.

I love the fact the new k6 gixxer 750 wieghs 2 kg more than the 600 Laughing

You get like 20+ more hp and 15 more in the torque range Laughing If I cant afford a thou I will deff be looking for a 750.

Nickey Hayden has been riding on a development chassis with the RCV motor in it. I'm pretty sure the chassis they'll be using next year will be somewhat different to the one he's been using so far this year. Using a development chassis hardly qualifies as riding one of the new 800cc bikes like people are suggesting.

Fair enough the lighter bikes do handle better. But which 750 has a better power to weight ratio than the litre bikes.

Power to weight ratios for the sporty bikes are roughly

600 0.7
750 0.8 (latest gixxer)
1000 0.9

Anyone else heard of the new 800cc Duc thats a fast as this years already even thought its only 800cc ?

Its in one of the MCNs i got, I dought the 800cc limit will make things more "competative" if thats what they're trying to do ...

Peak power may well be equal to the current engines but what matters is the torque curve characteristics, and I very much doubt they'll produce more torque than the current bikes. I'd be surprised to find lap times affected that much though over the current range.

I'm sure that during the Mugello race, one of the Eurosport commentators said something about how well Hayden was doing and imagine if they took the 800cc engine out and put the 990cc back in. Thinking

I wouldn't imagine they'd be slower over a full lap, but they are going to have more of a peaky power curve and therfore more difficult to ride, i'm looking forward to next year already!

750's have a better power to weight??
ay??
goin on rwhp figures and dry weights the suzukis are
600- 107hp(125bhp) 161kg
750- 126hp(148bhp) 164kg

they are dry weights. Fill it with coolant and oil, and i think the margin gets lower. I've been investigating this, as i was informed that 750s did have a better power/weight ratio, but i can't seem to get reliable figures for the weight, and manufacturers horsepower figures are normally a little optimistic.

750's have more torque and power for not alot of wieght gain which makes them more usable on the track so Im told Shocked

No, he's on a development bike with different parts from the other riders but he's on the same engine capacity. There is no way that Honda (or anyone) could have made an 800cc bike that was that competitive immediately.

I'd also be very surprised if the development 800cc bikes are as fast in a straight line. Doesn't make sense. If a manufacturer has an 800cc engine and a 990cc engine then you'd expect the larger engine to be more powerful, and thus propel the bike to a higher speed. Don't forget (before someone mentions it) that weight makes very little difference to top speed. I can well believe they'd carry more corner speed though, which ought to be good for Stoner and Pedrosa next year.

Nah, they are saying that the 800's are as powerful at the top end but with less midrange - a peakier power delivery. Don't forget that not only can the 800's rev higher (which is what you need for power) but also that the 990's have gained little power in the last couple of years as they already have more than enough. They have been after more useability - which they have just lost with this move to 800's.

The 800's are also smaller - more aerodynamic.

[edit]
It was also the Ducati (fastest 990) 800 being compared to the Kawasaki (one of the slower) 990.

If they are as fast in a straight line then the authorities have failed already, because it was straight line speed they were trying to limit. I find it staggering that some of these guys clear 200mph down some straights... anyone here who has done a trackday will testify that the straights are not half as long as they look.
