Would you give up your Thou' for an 800cc MotoGP rep?

[BarBender]

No.
Too small.

Roughly speaking, acceleration = torque / weight. If all other things are equal, a bike making 100 ft/lbs of torque at 2000 rpm will accelerate as fast as a bike making 100ft/lbs at 8000rpm. The top-speed of a bike though is generally determined by the peak power of the bike and its aerodynamics.

If your torque is higher up the rev range you will have to abuse the bike more to get to it, unless you like starting at high revs.

it still depends on the many many variables on how a engine was tuned to deliver its power...

[Nutter34]

Well, what does the average Gixxer 750 deliver now and where? How/where does it fit into the scales below? (Obviously as a reference, as an 800 will be a bit better/more)
I believe the discussion is for a road based bike, so it will be tuned accordingly...

If you compare torques only, any of the litre bikes has more torque at 4000, than any of the 600's at peak, around 11000-ish.

Found an older Superbike mag test... A K6 Gixxer 750... 132,5hp @ 13,1000 and 58,2 lb.ft @ 10500.

And yet, they still sell in great numbers. I agree on the 600 point, being able to screw it made it more fun to ride for me... I think I'd have misssed that on a thou. A nice buzzy motor gives more of the gp hero experience, if you see what I mean?

In the end, it might not even be in the hands of the manufacturers as to what we get... legislation might kill the hyper bikes before any market forces or whatever come into play.

the appeal of the biger bike is the lazy power on tap .if you ride every day every where you go you dont want to be ringing the nuts of a 600 all day just twist and go on the 07 gixer thou made for town and open road with the twin pipes or stop pissing around and just get a hayabusa.the 07 gixer was my choise of the 07 thous i test road befor geting the new bus if the gixer had a better rear seat we would have one instead. i found the zx10 to be unhappy around town with a heavy clutch

[avgas]

bring back 2 strokes!!!

Bike a delivers its spread of torque at a higher rpm then bike b. Starting both bikes from say idle in 1st gear, which bike will accelerate quicker from standstill, without slipping the clutch?

Quite right about the heavy clutch on the '10, I made the mistake of picking mine up once I'd bought it at 4pm on a Wednesday from Hunua. Riding back to Massey in peak rush hour turned into an ordeal as my right wrist turned to jelly. It's great on the open road, but I avoid traffic like the plague (well that's good then!)

Heavy clutch... Sore right wrist... You must have got an European or American version where the controls are swapped over...

[Nutter34]

But yes, The 10 does have a heavy clutch. Rode an '06 R1 and the clutch on that was as light as the Z1000's was.

The 10 doesnt have a hydraulic clutch to save weight....pussies

[R6_kid:Me]

Im likely to sell my 1000 for a 600 so i think the 800 wouldn't be such a bad step. Truth be told, whould it be any different if the ZX-7R and R7 were kept in production and developed over the last 5-6 years? Then only honda would have to come up with something in that field.

I'm sure if the market was competitive then the 750's would be the best balance and many people would be riding them instead. Of their 1000 or 600.

Right now i can't justify owning a 1000cc bike other than it came up at a good price... the power on tap is OTT and takes more maturity than i have to keep my licence in my wallet. Modern 600's are getting to the point where they are able to make 135hp at the wheel which is as much as an R1/GSXR/CBR from 2000 was making (ok so the 1000 is stock and warn, and the 600 is modified and brand new)... but you still get that bit more ease of handling on the smaller bike.

I think if Yamaha sorted out said 'vibration and reliability issues' i would be dead keen on an 800cc version of the R6/R1... im sure lots of Honda riders would move to a v4 or v5 800cc bike too. For Kawasaki and Suzuki it's a bit moot, both companies have 1000cc bikes with cult followings, and increasing competetion in the 750/800 bracket may not neccesarily sway those customers away from their 1000cc boasting ability.

Would i swap my 1000cc for a 800cc Replica - Hell yes

Only Suzuki make a 750, and that is only because of its heritage. Racing gave us the 600 and 1000cc bikes.

But the torque levels between them are vastly different. A 1000 pulls much better in top gear at 100km/h, making it an 'easier' bike to live with.

I think the remarks made about 'vibration and reliability issues' were made in reference to 'big bang' race engines, not Yamahas in general.

Ahh... ZX7R, and R7... both are 750cc bikes, i was meaning if both the R7 and ZX7R were still in production there would be more reason for development in that class of bikes. Suzuki can do what they want with GSXR750 as long as it is a good balance between the 1000cc and the 600cc.

Yes i know that, but if you are a good rider, utilising the cornering speed of the 600 sort of cancels that out in twisty roads. The amount of acceleration available at 230kmh on the GSXR1000k3 scared me more than doing 265kmh on the open road on my R6.

I know that, it's to do with the M1R. I was saying that if they engine could be made reliable and have less vibration (to warrant it going in a road bike) i would be keen on one.

There was a write up about Virgin Yamaha in BSB testing their 05 R1 in a 'big bang' setup, it can be done if you want but it costs $$$

I'm not talking about being the fastest through corners or making up for anything in regards to that. Read my post again.
