Basically that's what they've done for the '07 Gixxer1k.
I guess they were for a busa look?
its growing on me. well have to see when they come out to make a final judgement
I'll need to see it in person first.
those cant even be considered shorty pipes either
it has traction control...pretty cool
No traction control. It has a switch on the handlebar that changes through 3 engine maps for different condtions...such as rain. So it is not a true traction control. None the less, it is a extremely cool. I dont like the duel exhaust either. But they say the new gixxer has a lower center of gravity because of the exhaust.
I like it, but need to see it in person
And the pipes are that length b/c of the engine size
the mapping is very
They butchered that bike.
I must admit the switching between fuel maps is cool and all but I can imagine some major bugs that could come with that.
It may have a lower COG...but those pipes=more unneeded weight.
New pipes are because of more stringent emissions regulations.
Still, I don't see why they couldn't have gone with double shorty exhausts.
double midship exhaust would have been acceptable maybe, but either way its more unneeded weight.
it just keeps looking more and more like that POS busa
The aftermarket will look after those duals. Fuck, I wish suzuki would do a under tail system on their gixxers.
Pipes make it look way too bloated imo. It looks like a sharp, straight-lined version of the busa. Just as ugly.
2nd pipe is a photoshop, look at how the reflection is identical (but reversed) on both pipes
it looks good.
15th poster is an idiot, pics are on the suzuki website
undertail is only for looks and some times , very rarly you can use the clearence excuse I think DiSalvo, eBoz, and Spies have mentioned dragging their exhausts on the 600s...
just thinking about the undertail stuff and it doesnt make sense
I had read a couple articles reguarding undertail exausts. And in a couple of them, they had MotoGP aerodynamicists (namely Honda) that said useing an undertail exaust was crucial in the aero of the bike, becuase the hot exaust, and therefor less dence air due to heat, coming off of the trailing edge of the seat cowling provided for better laminar airflow off the tail section of the bike, reducing drag wake. An also had an added benefit of reducing turbulence under the tail of the bike where a swirling low pressure area is created from the spinning rear tire. And supposidly the exaust outlet at the leading edge helps to suck the low pressure area out the back.
That said though, Yamaha has done (so they claim) equal wind tunnel testing with the undertail exaust, and claim to see little to no improvment in laminar flow over teh bike, and no reduction in drag wake. But did cite an increase in weight out over the rear of the bike that effected the bikes center of gravity, and weight distrobution. And that the increase in lap time through mass centralization was far greater then some junk science about placing the exaust outlet on the undertail section of the bike.
I think in terms of street use though, 90% of the undertail exaust systems out there are strictly for looks.
In racing there is at least one benefit. And that is the exaust system is less likely to become damaged in a crash. And if the crash is gentle enough, you can pick the bike back up, and go with little more then some road rash to the skins. Not to the ecaust pipe, its hangers, and other chassis hard parts its connected to (like a resulting bent subframe for example). And sometimes the added cornering clearence. But again, going back to Yamaha's MotoGP bike, they say that isnt a relatice conscern either.
So choose whichever school of thought you want to, and take it for what you will. Becuase no one really has a difinitive answer about it.
yea, and no auto/bike manufacturer has ever used a photoshopped picture on their website, EVAR!
Motogp is the pinnacle of the sport. I wouldn't be surprised if there is some aero benefits from it but, I still say more piping = more weight also more bends = shitty flow. Although im sure that the piping on the gp bike is a hell of a lot different than way it is for regular streetbikes. for the 800cc machines they switched over to a slash cut pipe flush with the body, imho thats as good as its gonna get.
as for less damage after a crash I totally agree with you on that one
dual ext = ugly
any other angles?
