Dyno comparison of Ducati 1098 & K6 GSXR1000

[slowpoke]

A slow night on nightshift last night and in my never ending quest to find the limits of the 'net I came across this interesting tidbit. Here's a dyno curve comparison of a stock 1098 vs a stock K6 GSXR1000. The 1098 kills the GSXR through the midrange but the GSXR makes up for it at the top end.

the top end isnt much good for normal road riding

Dry weight of the ducati a few pounds porkier. I hope it has the cornering advantage though, and with that torque it might be able to get a higher top speed on a limited length straight.

They're a pretty even match.

both bikes are not desined for normal road riding test road the k7 gixer on friday 200km second gear wheel stand in a fifty zone dident need much road to get there eather just a pity about the rear seat being to small

However they are geared for about the same top speed, so stretch the red line to the right (in your imagination) so that the peaks align, and that will give a more realistic view of a side by side roll on.

Curve for the Duke looks kinda wonky. Would have expected better from the Italian tuning house? Why the dip in power in the mid-range?

Why the dip in power in the mid-range?

If you are referring to the dip around 5000 RPM you will find almost everything dips at 5000 because that's where the emissions testing is done.

Why not just compare your 7 year old Hayabusa ? 100 hp at 6ooo and 150 at 8000 !!! I would rather have one of those !!! Gaz.

No, the Suzukis midrange is just higher up the rpm range than the Ducatis (since its redline is much higher its midrange will also be much higher).

Since the Suzuki trace stops at 12000rpm, mid point is 6000rpm and it makes just under 80hp here.

Since the Ducati trace stops at 10000rpm, mid point is 5000 rpm and it makes just over 60hp here.

Suzuki has stronger midrange.

Yep

Suzuki has stronger midrange.

And yep

paturoa has it right. Just comparing raw curves without taking gearing into consideration can give a very skewed view of reality.

The torque curves measured at rear wheel speed, rather than engine speed would be rather telling.
