This is probably old news, but here is a comparative dyno chart, matching the mighty FZ6 aganst 3 of it's closest rivals in the naked, or non pure sports, middleweight bike category...

Note, these are real world figures, quoted from power at the rear wheel, not at the crank, like most manufacturers claim.

As you can see, the FZ6 walks all over the other bikes in this test in terms of outright horsepower....

But then you add in the newer Triumph Street Triple 675, and the FZ6 has met it's match in terms of outright horespower

Then there is the Aprilia Shiver....with it's 3 different maps, for the 3 different power options available in modes A,B, or C.

Not forgetting, the Kwaka ER6N, and the newset of the middleweight's, the Suzuki Gladius.

In the end, here is the honour roll, remembering that not all figures are from the same dyno....but am guessing the figures quoted here are not far from being spot on.

Kwaka ER6N: 62.94hp @ 8800rpm
Kwaka Ninja 650r: 64.8hp @ 9000rpm
Suzuki Gladius: 67.12hp @ 9000rpm
Suzuki SV650: 71.6hp @ 8750rpm
Aprillia Shiver: 76hp @ 9300rpm
Honda 599: 82.9hp @ 11,750rpm
Yamaha FZ6: 90.4HP @ 12000rpm
Triumph Street Triple: 91.1hp @ 12,100rpm

The Yamaha FZ6 can hold it's head high!

nice comparison, i would be interested n the torque specs though, the Shiver and SV650 should walk up and down the FZ for that spec since they are V-Twins, I am not sure how the 650R would do since it is an inline twin.


I love the HP of my FZ, but would love some torque of a twin to play with!



On a side note, you can tell that they used the 1st gen FZ for the dyno, it is a lot peakier than the 2nd gen FZ6.

Yes, was going to post torque curves, and bike weights......but sorta thought that that was enough info to digest in one thread....

your right though, the twins, and especially the v-twins all have their power available at lower revs, as well as having considerably more torque...especially in the mid range.

As for power to weight comparo's...that's a bit harder, as it's just about impossible to find the true weights of each bike, as manufacturers weigh them differently, some with oil, some without, etc, etc...as do the testers....

:thumbup:
 
HP is where all the fun is, but having Keira's bike being an SV650 (which i get to ride every so often) shows that each has it's own use, The FZ is far better for me overall and much more of a rounded bike, but in some aggressive roads the SV sure is a ton of fun!
 
Yep, as the other's mentioned, the torque curves would be nice. But really, for as much as people complain about the lack of power and torque of these things, i don't see it. Sure you have to keep the rpms up a bit, but that's how it's geared too. I'm comming from a '02 BMW K1200RS, that thing had a good 40 hp on this and probably twice the torque. The roll-on power was great, but i get into just revving the living piss out of this little motor and it seems to love it. That the FZ6 weighs a good 200lbs less than the BMW, a HUGE difference that i can always feel.

Yeah, torque is fun from the bottom on some of those twins. Was scrubbing in a neighbors tires on his Ducati Monster 620e and was pleasantly surprised at how it accelerated in first and second gear. I had a lot of fun with that twin but was missing my FZ6's attributes in a short time. I just really like what Yamaha has done in their design of the FZ6 and also believe it's the best of it's class. Considering it's design the FZ6 give back so much when you push it. The other day I was riding with a forum member 'westgoingzax' and we we're in a parking lot when a guy who rode a GSXR looked at the tires and asked, "You ride those like that?" I said with a grin, "Yeah!" :rockon:

I sold an Aprilia Shiver to buy my FZ ,around town in Sport mode believe me it would leave the Yam for dead,open road other way round.
I loved my Shiver but got fed up with its reliability.
 
The FZ can be a screamer around town too.

I've never cared for the whole down low torque debate. the fact of the matter is, like any high revving small displacement engine, its designed to be efficient in the mid to high rpms. If you look at the fz6 power curve chop off the top three thousand rpm and add it below, you get a torquey twin. But it's not designed that way.

HP is a function of rpm and torque. If something revs much higher and has a broad torque curve it will have more hp. It can do more "work".

So, if you use the engine the way it's supposed to be in the 7000-8000rpm and up, it will feel better and most definitely spank the others around town.
If you took those anemic twins to 7000rpm+ it will be crap cause the torque is falling flat on it's face.

It's a two way street. and where a I4 is great, the twin is choking and vice versa
 
Or do a sprocket change. -1 +2 makes the bike a completely different animal. Power comes on much quicker. I love the way it behaves even more now.

are u saying my 2009 makes less peak then an 06? i know they made some Fi changes, but did it lose some top end?

Yeah ,I agree ,I loved the pick up but missed the top end I had on my 04 FZ,plus when it got below zero it was downright dangerous in any mode(I had a nice January slide up the road).
The FZ is a much more sorted bike although I sort of miss the Shiver(with Akras she sounded awesome,listen to them on youtube).:thumbup:

Nope you make just as much power, it is just smoother. Check out my Dyno run and compare it to the one in the article. Mine is an 07 and has the same FI as the new 09's. see how much smoother the line it and less peaks, like as in sharp upticks.
 
If you want an engine with a lot of torque ... you shouldn't even bother with a 600 cc engine. Get a liter bike. And if you want the most, get a twin liter bike.

I sometimes don't really get the point. If you want a horse, dont buy a donkey ;).

Nice to see how flat the honda's torque curve is, but flat curves are boring rides. Peaky curves are more fun :D.
The power the FZ6 makes as a sport-touring 600cc bike is excellent. All the power you need for the everyday riding and the fast road-track riding. If you want to go really fast, why buy an FZ6 ... :confused:
