2014 Duke 690 Rookie, mod suggestions.

Hey, new to club Duke, just picked up a brand new 2014 and trying to get a general consensus of where I need to go with the intake/exhaust/fueling mods to get the bike running at its peak. Went to my local shop and they are at $3000 (canadian) for the full AKRA kit installed and this seems like a bit of a rip off. Anyone have some good options if a guy was to get all the parts on ebay ect...?

Intake- Is just a new filter good enough?
Exhaust- Slip on or the whole kit? (not looking for louder)
Tuning- Seems like I need tuning and Kev's kit?
Cam- worth it?

Thanks for any suggestions, loving the bike so far just need to open up that motor a little.

There is not much more you can get out of this engine.

You can get the tuning kit with the cam, intake, and fuel map if you want to boost the top end power of the bike and get 1k more RPMS.

For exhaust you need a full system or none at all. Leaving the cat there and putting a slip on is a waste of money. You can eliminate the cat with the Fresco midpipe if you want the cheaper route.

A piggyback fuel system along with the fuel map flash from KTM will definitely smooth the bike out in the lower revs.

Just curious about your Duke. Is it the R model? Because, as far as I can see, the most useful mod that one can make to the basic Duke is to improve the suspension. Of course, I am a very slow rider, and I did re-gear to 15/42, but, the power seems adequate for everything but high speed stuff, and a few HP gained at big expense won't make almost any difference there. Also, although the bike protests when run at less than 3000 RPM or so, I never notice this, as it is so easy to avoid running the engine that slowly. In fact, I worry instead that screen dumps from my GoPro always seem to show my tach needle way up the RPM scale, and with 15/42 gearing 70 mph indicated is 5000 RPM. I don't ride freeways unless I have to and, I just take it on faith that a giant 690cc single can buzz along at 5000 RPM without fragging.

So, if you don't want more noise, and you are fixing to spend some more money, I would suggest reading up on suspension tweaks since I assume since you want more HP, you are already a fast rider, and, in that case, you should find the nonadjustable suspension kind of soft when you start to really push.

Unless you just enjoy modding or want the bike to look different, I'd just ride it and save the money. You can change the profile of the rev range but not a whole lot of actual HP with most mods available.

If anything, get the fan temp switch and Kev's O2 mod.

I would get rid of the exhaust and cat for weight savings and there are lots of options besides akrapovich that cost less. Intake is fine although I do have a k&n filter. Kevs 02 mod is a must and if you have any fueling issues go with the akra map if you can get it. Cam is nice down the road if you get board with it. Suspension upgrades help the non r if you frequent the canyons.

Thanks for the tips, I don't really take issue with the low rpm smoothness as I find it can be ironed out by ridding style and a little extra attention on the throttle. Coming from daily driving a Subaru STI, where the stock tune is dangerously lean/power robbing and a quick tune adds reliability and about 20hp, I wanted to make sure I wasn't in the same boat with this KTM.

My model is not the R, and this is my first bike, so I have a long ways to go before the stock suspension is holding me back. Sounds like the power mods on the duke are probably not going to get me a significant boost, so I think I will save the money for the Duke R rear sets, and some touring bags/suspension work down the line.

Ready to race as they say, already. A couple of minimal horsepower gains for a lot of dolleros. Cheaper decat and pipe options than the akra are out there and are just as good. The suspension should be ok for the road as well if you are in the 80kg / 180lb range also.
