The Torque-Curve

[MadDogMcQ]

I was telling a friend recently about the huge 100ft/lb torque of the FJR1300 and he asked what revs were required to reach that 100ft/lb. I told him that it was somewhere around 7000rpm and he said he preferred his torque to be produced at much lower revs. Well hell yes, so do I, but I didn't have sufficient knowledge to point out to him that even at 4000rpm it produces xxft/lb.

Anyone know what the torque-curve is over the rpm range?? Be interesting to know.

Here ya go:

What kind of bike does your friend ride?

Thanks JW but that looks like a BHP curve.

Found the same one, jwilly beat me to it, note that the units are metric.

Looking at that chart then thinking about riding it at full throttle from 6000-8200 rpms gives me a woody.

Tell your friend if he can find a bike that produces 100 pounds of torque at 4000 rpms, I'll buy 2.

 

[STL FJR]

As you can see, torque is pretty good between 4-7k rpm ...

A quick search online found these two:

Triumph Rocket III

Maximum Power

140bhp at 6,000 rpm

Maximum Torque

147ft.lbf at 2,500 rpm

Honda Valkyrie Rune

Horsepower: 90.6 @ 5250 rpm

Torque: 110.9 ft.-lbs. @ 2500 rpm

I'm sure captain america can add a chart or two to this.....though, they may be somewhat disheartening.

Tom, also remember that gear ratio is just as important as engine torque. Oh, and at 3,000 RPM a FJR is at only ~20 MPH in 1st gear. So, you get to the fat part of the torque curve quickly. :yahoo:

Nice! Just wanted to let you know that this little dig didn't go unnoticed. :clapping:

No prob....um....."gunny"?

Don't you mean 4 tanks!! Both 700+lb cruisers! :glare:

Here is a torque curve of the FJR and the ZX-14:
