Your problem is using a Honda dyno.

That will lose you 10 hp right there :wink

Seriously, and not rag on your bike. But don't 600s usually pull in the 110hp area?
 
#12 ·
True. I'm about 200lbs he's probably 150. Either way it doesn't matter to me. As long as everything is smoothed out and it runs good I'm happy.
all comes down to rider anyways




No not really... Weight plays a factor too... He could be 25lbs less than you and you'll be extremely disappointed when his crotch rocket beats your crotch rocket.. Lol

Just curious but why does the power band dip between 9,000-11,000 rpms.. I see were your power really builds which is kinda late compared to my "butt" dyno.. Lol.. Do you have your set valve deleted? Just curious because back when I had mine still in you could feel the power really build around 8,000 but now it seems to really build around 6,000-7,000.

That might be why.. I would have deleted it then put it on the dyno.. But hey I'm sure you'll enjoy the bike. Plus air temp, elevation, dyno play factors into it. A graph is suppose to be pretty straight after a tune. I might try to find mine from when I had my old car on the dyno and show you an example.. That drop just makes me wonder. I'm sure you cant tell though when riding..

Thanks. Guy seemed to know what he was talking about after the tune was done. I was referred to him from a buddy that used to race so I figured he would do a good job. I think sometimes people get too caught up in what the numbers are. I just want a smooth running bike with a little power increase for the mods I done.

When I had mine dyno'd from the PCV map to a custom map, I picked up a few ponies but lost some of the smooth curve on the graph. At first I was not happy with the shop but they told me I would not be able to tell the difference beside the gain of power and they were right, I cannot feel the difference at all beside the gain of power when I toggle between the two settings. The acceleration is a smooth as butter even though the custom map curve is not as smooth as the PCV map so yes a smooth map is important but there needs to be a balance for what you are paying for. Smooth is important but a gain should also be part of it since a line that's just a bit smoother may not be something you even notice if there is no other gains such as power.

Here's the 600's(and a 600'ish) bike I have had, all on the same dyno, by the same tuner, etc...

Also had a Honda 600rr that made about 104hp... My buddy's 2008 R6 racebike with a full Akro system and a Bazzaz box and custom tune, made 112hp at the wheel...

So taking into account a different dyno, different elevation, different humidity, etc... Your results of 104hp are in the range of where that bike with those mods typically runs...

If you look at the GSX-R600, the power kinda stops at 13k or so on the tach... there is over rev, but the peak power is kinda low. Maybe a full exhaust and some more tuning would get rid of that flatline, but from what I have seen, that is pretty much standard on GSX-R's... My 750 is the same way...

That torque curve on the 675 is really interesting.

I rode a friends Street Triple R recently and it was a blast.
 
#31 ·
Yeah. I with that the Street Triple wasn't detuned from the Daytona setup.

But my thought is that if they had the full blown Daytona motor in a naked bike that light and agile, that performance wise, it would cannibalize sales of their flagship, the Speed Triple

My 2011 Speedy made 122hp at the wheel and monster torque, but it weighed like 80lbs more than the Street Triple... So HP/Weight ratio would be almost the same, with the Street handling a LOT better...

So Triumph neutered it a bit to keep the market segmented.

It is however a fantastic bike. The Daytona is too. Handling is on par with an R6, but the ergo's are a good bit better, and the motor is brilliant. Torque everywhere, but a screaming top end that stands toe to toe with any supersport out there, and better than the majority of them.

For the same price, with a 2 year warranty, a bit of character and the cool factor that comes with a Euro bike, it is hard to beat.

I considered one for my last purchase as I loved my 2007... But the Panigale was $15k, the Triumph was $13k and the GSX-R was $9,300... so the Zook was a no brainer...
