Yama got the specs wrong?

**Biff** · 11th January 2006, 11:40

Read an interesting report in a bike mag last year about manufacturers claims (BHP, dry weight etc). Basically it said that all manufacturers figures are pretty much BS.

During the bike mag’s own tests they could get nowhere near the claimed BHP or dry weights claimed by the manufacturers, with Yamaha being the worst. An alleged Yamaha insider actually stating that when it got to publishing the BHP figures for the '05 R1 they looked at the competition’s figures and then made up a figure that made the R1 look competitive.

We all know that the R1 is more than competitive - so the conclusion I draw is that every fker lies/exaggerates.

Looking at those dyno runs, I'd have the gixxer any day. It makes more power for most of the curve (at same RPM) and more torque everywhere. Power curve is far smoother too.

Bring on the gixxer!

Saying the redline is higher than it is is nothing new. Honda claimed the CBR250 had a redline at 18,500, but when I measused it, it was 17,232.

I revved the ol' CBR further than that when I found false neutral

Am I missing something here?

Who cares what the redline is?

Its where you get peak torque and power, and for how much of the rev range its in the top 25% of the available power and torque.

Then you just gear the bike accordingly...

it's more the point that Yama are claiming BS
plus, the technology that goes into such a high revving engine is kinda breakin old rules, it could be a new era of higher output engines for smaller cc's. If it isn't so, then why cry wolf?

You can see where it drops off. Dyno runs always go close or to the redline, which is that claimed 17,500, but the chart shows no where near 17.

Still a fast bike (see the bhp in the bottom corner), but all the same..

Can I just say that I'm loving the fact that the new model R6 makes 3 more horse power and a SHITLOAD less torque than the OLD model Gixxy Six?

Thought I could.

Thanks for listening.

We always listen to you WT, sometimes it just refuses to sink in.

You can raise the rev limit (and power) till the cows come home and all you'll have is a fast track bike and a gutless POS for normal road use.
One of the Pommie bike mags detuned an R6 with various Thundercat bits, they ended up with 3 hp less than standard, but much more low and mid-range torque. Everyone who rode it preferred it to the standard bike.

Roughly, but too many Poms ride 636's so they aren't too popular.

Yes thats correct Dynamytus50 the R6 is clearly better than 636 [and CBR600]..........all clearly inferior to the GSXR600 which is the best of all [eh buggy hehe]

on paper, the 04 R6 and 636 are equal. You could call the 636 a cheat, cos it's 636cc's where as the R6 is 598cc and develops the same power etc. The 05 636 up'd itself a bit, and Suzuki tweaked the K5 600 (I think), but Yama and Honda didn't really do anything for 05. So now Yama have released their 600 eater, so at the moment, it's the best - on paper. But the cracks are already showing, which isn't great for them. Honda really need to crack the whip and get a new 600 out.

Sniper and SPB are gonna get a kickin tho

**WRT** · 11th January 2006, 15:01

Well, if you werent happy with "just" a 600, then why only jump up by 36cc's to 636cc's? Why not go up by a more worthwhile amount and get say a 750?

Oh wait, thats right, they dont make em any more. You'd need a gixxer for that, too . . .
