You have got to be kidding me
So what you are saying is that KTM expects its customers to spend over $2,500 for an exhaust system for a SINGLE cylinder motorcycle? And until they fork over the cash, their bikes aren't going to run worth a damn?
For some perspective-- $1,500 buys you a full TIG outfit! You can make as many exhaust systems as you want! I made mine, and when I told the KTM rep that I MADE my pipe, he dismissed me like I had just drawn a mustache on the Mona Lisa.
All I need is a fuel map, $2,500 exhaust pipe?--no thanks. Hell I'm about to rip off the throttle body and replace it with a carb!
For what it's worth, even though my Duke is running super lean, It is WAY faster than the stock set-up. Let me say that again - WAY faster. I have power all over the place, low, mid, and high. The front wheel comes up at 1500 rpm now. The power delivery is a bit choppy and abrupt, she pops on deceleration (lean state of tune of course), and my spark plug looks like casper the not so friendly ghost, but man if there was ever a motorcycle that benefits from a de-restricted exhaust, It's this one.
Gentlemen, if you will allow me, I would like to give you my take on single cylinder motorcycle exhaust systems. It ain't subatomic particle physics. See there isn't a pesky merge collector to deal with (primary and secondary tuned lengths as for multis), so all we are talking about is one primary, length and width. In a racing application, where every fraction of horsepower counts, bring in the engineers. For the street, make the header as long as is practical, put on a free-flowing muffler and jet accordingly. OK so I might loose a couple of hp on the top end (verses the "factory engineered race exhaust" not epa approved stock version), and insead of loosing 10lb, I loose 9lb. So what? How often am I really going to rev my single cylinder motorcycle past it's powerband anyway? Dude, if I'm sweating 1lb on my streetbike, I should cut down on the bacon cheeseburgers first, right? It's called diminishing returns.
Ever take apart a high dollar exhaust cannister? It's a perforated tube with muffler packing. Same as the el-cheapo one you get from autozone for tuner car honda civics. Do you think that the exhaust gasses passing through that perforated tube know the difference? Do inanimate gasses decide to move faster or slower based on the label on the outside of a muffler?
What you are paying for with the Akropovic system is the luxury of a bolt on exhaust. I for one, do not require that luxury because I am a hot rod guy, not some euro-douche with fancy shoes and an ipod.
I guess that I am mad at myself for getting suckered in by KTM's marketing message. They portray themselves and their customers as rugged individualists, as opposed to Ducati's elitist user imagery.
AAHHH!! my head hurts!! KTM, just give me a freak'n fuel map download, PLEASE!!!! ---JT
