Powerband & Red Line

[Craggles]

The thread about red-lining made me think about a bikes powerband and where the red line is..

So I'm asking... what bike(s) do you have, and where is the red line, and what range is the powerband at?

I'll start - I have a 2001 4 stroke GN125, Redlines at 10k, Powerband 5 - 7.5k.

I really hope I've used the right terminology referencing the powerband... or I'll look like one of Stes ebay customers!

91 AR125, powerband about 7k onwards.

[iCraig]

I have a GPZ500S, it red lines at 11000RPM.

And it really doesn't have a powerband as such cos its 4 stroke and power starts at about 2500RPM.

But there is a noticable surge at 7000RPM up to 10000RPM, so I spose you could call that powerband/range.

My TZR125 (based on my limited experience today) would seem to really kick in around 6k plus.

Hi

Lets see.

Aprilia AF1 '87, red line at 9250rpm, power starts at about 7000rpm.
Aprilia AF1 '88, red line at 10500rpm, power starts at about 8000rpm.
Aprilia RS125, red line at 10500rpm, power starts at about 8000rpm.
Cagiva Freccia C12R (ex road test bike), red line at 10000rpm, power starts at 9500rpm and finishes at 11000rpm.
Gilera CX125, red line at 12000rpm, power starts at about 8000rpm, but has a slight second kick at 11200rpm.
Yamaha Diversion, red lines at 9500rpm (I think), and no rea power band.
GPZ500S, red lines at 11000rpm, power comes in at 7000rpm.
FZ750 red lines at 10500rpm, no real power band just a good build up all through the rev range.
1200 Bandit (slightly tuned), red line at 10000rpm, power comes in very noticeably at 7000rpm.
Bimota YB10, red lines at 11500rpm, power comes in at about 5000rpm and more at 7000rpm.
Yamaha FZR600, red lines at 11500rpm, power comes in at about 7000rpm.

Cbr400 gullarm, redlines at 14,500rpm. I'd say the "power" doesn't come in untill 7/8,000. But 10,000 is probably where it really starts.

[Andy99]

No need to redline the R6 as the power tails off just before it.
Just change up at 14,500RPM,nice

I quite fancy printing a custom tacho face with a circular dyno graph integrated into the tacho.

Dunno why, just think itd be cool, and possibly useful.

XR 125 - wish i had a tach to see my revs but i feel that the powerband kick in at around 4k-7k and redlines at 8k. It's very grunty once you get it in that zone and most cagers WILL get overtaken if i'm in 3rd gear down Kenton Lane.

Last bike I had, TL1000R, a litre v twin. Power right the way through the revs.

[ProXimaCore]

GSXR400R - Redlines at 15,000rpm. Power kicks in around 8k right to the redline. It lacks power below 4 really. I tend to ride around town at 4750rpm as that's where the exhaust sounds nicest for some reason. Also happens to be 30mph precisely in 3rd gear.

[Rollins]

I wonder where the power lies in a Honda CBR250 - 19,000 rpm redline anyone??

My RS125 - redline @ 11,000 rpm, powerband - dead below 5k, a bit of go between 5-6k, then it starts to shoot. Apparently there's a huge leap at 8k, but being on the right side of the law, I don't know just yet.

2004 nxr 125. No powerband what so ever.
Also got a nsr but it blew up

Do all bikes have rev limiters?

My tzr250 redlines at 11K and there is a very nice surge of power at 6K and then it goes again at 9K.

Is the dyno output from mine, it redlines at 11.5k, max's out at 13.5k
As you can see from the dyno the powerband comes allmost in 2 stages with a noticeable lul in power in the middle. Peak power is produced at 10.5k with a sharp drop off in power before red line. hence there is absolutly no point in redlining my bike

[John]

VFR Picks up power from about 6K onwards. I think peak is at about 12k.

I like the sound though, so usually It goes all the way to 14.5K.
