PC5 + Autotune + cool mufflers happening soon, will keep you posted.

Yes, you can tell from midrange up (5k to 7K rpm - 3k range), the KTM has a high rpm cam, which is good IF this is the range you ride in normally. It is very stressful on you and the bike to maintain constant high rpms, especially off road (and on road, it will take your license away). The Terra engine is pretty close to perfect in performance reliability mix.

Now I see why Pierer is so nervous about the competition

To be honest I dont believe that is a KTM 690 being taken into account. Rather earlier 640...

KTM 690 is evaluated here - blue is stock (60 HP) and red is 'open-muffler' (67 HP).

True. A single bike on a dyno can be throttled to tell lies in both directions. When you have a 2 or more bike comparison, at least you have an assumed base measure. 5 hp difference is virtually nothing in disjointed runs (humidity, operator, heat, rear tire worn-out, time of day, motivation, ...). For the KTM alone analysis, an 8 hp difference, you would however suspect a tuning change is required for the near 70 hp run on the open drag pipe run. Both of those runs on the same bike did not indicate the high rpm cam (which is usually reserved for drag racing exclusively), as indicated by the first comparison runs. So something is different for sure, but I'm not quite sure with the limited runs available. I would lean towards the multiple comparison runs versus a single marketing run.

Does anyone know how and if the cams were changed on the Husky 650's top end from the stock G650? There was already a nice Rotax cam on a stock G650. There were no increased deviations in mid or top end (where oem's traditionally like to 'juice' the hp at redline), so it is a reliable cam version regardelss (although a "high lift, short duration midrange cam" would be a hoot (!), like Web cam's for Bombardier DS650 - pre-2000 BMW F650 engine with carbs run from 2000 until 2008 for atv's.) A cam is probably not needed on the Husky 650 with the top end work already done.

Here is what I found...

What's New: Husqvarna's TR650 is an all-new global motorcycle that capitalizes on the booming dual-purpose segment. Available in two variants—the off-road $6999 Terra and the street-biased $7499 Strada—these minimalist rides are built around a 652-cc engine sourced from the BMW G650GS and modified for punchier performance. The Chinese-built single-cylinder workhorse features a lighter piston, a modified fuel injection management system, a higher compression ratio, larger valves, and a modified cam profile which helps boost output to 58 hp, a 10 hp increase.

Thank You! I was just looking at the Husky site and saw it. Yep, I would not touch a thing on this engine.

That was an SMC based on the notes in the run file.

I posted a video in another thread where they compared the new 690 Duke to a 650 Strada. The BMW engine delivers very smooth manageable power and is pleasant to ride. I am skeptical about the dyno charts posted between the Terra and KTM690. I have ridden enduro 690 is very powerful by comparison and about a hundred pounds lighter in weight which is a key factor not shown on a dyno.

So do you have to fab up some flanges for the three bolt mounting system of the new mufflers?

....that and no restricive CAT as well!

Man...I can't wait to hear these beauties! I am really diggin the red tip you had on your other bike!!!

Im doing shock/vibe testing in the bay area this week so hopefully my adhd on this will be paused till you get it all set up. Otherwise.....hook a brotha up with a sound clip asap!

Sorry bro, been offf my meds for a week now and I have reverted back to my mental "Bull in a glass shop" ways.

Are these available to purchase at this point or are you a test bed etc?

DynoJet is shipping direct right now. Distributors will have them next week.

I don't mean to hijack the thread but I just want to sort out all the "chip" options.

http://www.advrider.com/forums/showpost.php?p=16463654&postcount=1 - this seems to be a nice option just tricks the computer into thinking its 20 degrees colder - it has an option for warm or cold weather. $90

booster plug http://www.boosterplug.com/shop/boosterplug-husqvarna-233p.html - essentially the same thing but 60 bucks more expensive and only has one setting. $150

Powercommander completely replaces the stock computer, programmable maps, and optional "optimum" fuel/air ratio 02 meter. Their site is slow / not responding now but I think its $300 + for this option.

I don't have any experience with these how much difference is there between the "trick the computer" chip and the PC that essentially replaces it?
