Note: Streetfighter and Brutale added to the following list.

Thought this would be interesting. Listed in order from highest to lowest ratio.
Comparing mid-sized bikes using rounded off horsepower and wet weights:

Brand, Model, Horsepower, Weight , Ratio in Horsepower per Pound

Ducati, 848 Streetfighter, 130, 440, 0.295
MV Agusta, Brutale 800, 125, 435, 0.287
Yamaha, FZ-09, 115, 415, 0.277
Triumph, Street Triple R, 105, 400, 0.263
Triumph, Street Triple, 105, 415, 0.255

Yip! She's a beast.
Gonna guess...FZ09's usable hp/torque tops the list too.
Thx for sharing.

The KTM Duke 690 is nowhere near 415 lbs.... Just saying.
Yeah that's way off. It's listed at 330lbs dry. Something around 352 wet.
That'll put the bike at 0.19 so it moves up one spot.

I believe the 690 is about 330LBS dry.... so, maybe 355 wet?

whoops, posted at the same time

Always interesting to see the numbers side by side. I like to add rider weight when estimating power to weight. It gives a more accurate comparison between bikes that way. For example, my dirt bike without a 200lb rider is a .24 which is better than the GSR at .23, but adding a 200lb rider brings it down to .13 vs .16 for the GSR.

Gives validity to being a weight weenie, my bike, not me.

There's a guy on the local forum here that's easily over 3 bills...I'd say he's about 325lbs. He rides a Grom (Ohlins of course) with a big bore kit. It probably makes about 17hp I'm going to guess.

So that would make it .031 hp per pound.

The new Suzuki GSX-S1000, due out later this year. Is rumoured to have 145hp. No word on the weight yet...

Excellent observation and point made here.

Now if Steve will tell us his "true" weight, we can see how fast the red raper really is.

Good post...I applaud the effort. But if you wanted TRUE power to weigh ratios..you can't use advertised figures and crankshaft horsepower. All the manufactures lie big time...especially Ducati. For instance the average dyno hp to the rear wheel of an FZ09 is 106 not 114. The FZ07 claims 74 not 75...and it's really 65.9 hp to the rear wheel. The wet weight figures are all off too. Good topic though.

A comparison between the two bikes you asked for.

My 1290 has a bit more than my MT09, my 1290 weighs in at 420LBS fully fuelled measured & has 172 rear wheel HP, 20 more rear wheel HP when measured from standard, My MT is 18.7LBS lighter than when it was standard & now has 122 rear wheel HP. The Dyno runs below are both my bikes on the same Dyno both bike are modified & have custom PCV maps built.

HP



Torque

I double checked and the 690 Duke is officially 328lbs dry and 410lbs wet. I trusted my memory and was off five pounds. I'm correcting the comparisons. And, I agree with your thinking here, because I rode the 690 and it feels super lightweight.

Dry weight specs can be very misleading. Most mid-sized bikes that I've researched showed both dry and wet with a 60-70 lb difference between the two values. An 80 lb spread for the Duke sounds pretty fishy for sure.

When the 1050 Triumph Tiger came out in 2007, Triumph marketed it at 415 lbs wet. The real number is over 500 lbs.
Not so sure- Sport Rider says wet weight of the 690 is 356lbs.
