I could probably live with the fugly for the function. thanks for the pics.
MRA makes a similar line of screens. Made in Germany. I had one mounted and it was very solid. Did a great job but as we all know the 690 has headshake issues and the bar mounted screen made it worse.
Clearly we don't all know it, I have never experienced headshake on my 690... interesting though.
Yea, I'm with you. I've had it wag in the deep sand at 100mph but thats normal to me, part of the experience.
Let me help you out with some light reading.
We took the first pre-production tank mouldings today from our CNC machined aluminium rotational moulds today.
Once cooled,we fitted them to the 2012 690 Enduro test bike,and they were perfect!!
Now we can finalise fairing and screen tooling,ready for production.
Looks like you are set up very well for some adventure touring. I like your Touratech system cases but then again I like nearly all Touratech stuff. Scotts is also a nice touch. I have had them over the years and they have saved my bacon numerous times when I was not paying attention and hit large rocks, the deflection of which would have put me on my head but for the stabilizer.
I say we remove it from the list of known issues, assuming that some here have put it on that list. I have had no headshake, however I balance my tires which seemingly would only rule out thumping/vibration at various speeds but not headshake.
The only motorcycle I ever had headshake on was a 1964 Triumph Bonneville and it only occurred once, when riding down a long hill on the slab trying to see how fast it would go downhill!. On the flat it was good for about 114 mph. No headshake occurred under power it was only when I suddenly chopped the throttle back when approaching cars at about 120 mph. It was a real tankslapper and momentarily put me in touch with my mortality.
Absent setting up the suspension incorrectly as to sag, compression, rebound and/or loading up the bike like an RV I don't see it as an inherent flaw with the 690.
I always wanted to try this as I am a big fan of old western movies and I have seen other riders do it. Note to self: practice this (alone) next ride, on nice soft grass, if I can find it here in the desert.
I like the set-up~thanks for sharing
My 2010 690 Enduro has a Scotts Damper, but my 2008 690 SMC does not - and the SMC has much steeper rake / trail geometry. I have never experienced even a hint of headshake on either bike.
I just mounted a new set of tires (Metzeler Karoo T Front and Mefo Explorer Rear) on the 690 Enduro. The KTM Shop in Las Vegas who installed them is just off of the freeway. This particular freeway is grooved - man, the bike felt like it was waggin' / wanderin' around pretty good. It didn't seem to do that so much with the worn set of tires (same tires).
Will these tanks be exclusive for the 2012s or will it work for the previous generations as well?
Hey Crankshaft, you just need to wik it up a bit when that happens. What's the worst that can happen?
I never had head shake on my 690, but on other bikes it was always badly worn or improperly inflated/balanced front knobby. Sand is always a problem because the trail measurement always goes to zip unless you keep the front light.
I think Barman is referring to the steering wobble that happens at high speeds. I think it is a shape-of-the-tire thing, combined with freeway turbulence grabbing the rider's shoulders.
My old 950 had that wobble above 95mph when I used TKC80 front tires. They have a round cross section, as opposed to the more triangular front tires like the Scorpions or Mefo's.
My 12 690R can also have that wobble above 75mph so I added a damper that works well enough up to about 90mph. I still have my MT21 front, but I am pretty sure if I replaced it with a more triangula tire, it would be more stable at higher speeds. I like the tire, though, and I don't cruise any faster than about 80mph anyway.
In my experience a 'headshake' is a suspension or geometry issue generated by bottoming the forks through ruts, or an improper set-up on a road race bike. It usually surfaces under power on corner exit or an esses where the racer flipflops the bike. They can degenerate to a full blown tank slapper in a flash. I'm not sure the 690 wobble will turn into a tankslapper, but I will admit that it feels like I am loosing directional control if I don't stop it somehow. :eek1
Nice progress guys!
Maybe silly question ~ will this type of material (speaking of the tanks) allow graphics to be applied without bubbling?

Thanks for the kudos.
The bike resides in Las Vegas and was built to ride / tour out west. Yes, the Scotts Damper is a must for faster desert riding - particularly for Mojave riding with all of the boulders buried in the soft sand.
They have been designed to fit all years
that and grooved pavement and it wasnt scary compared to say a 90's cr500
the head shake Ive experienced it gets worse when the throttle is chopped . a trick i used on the 90's honda 5hunnys is to drag the rear brake. never figgured out the cause of the shake but i had some see Jesus moments on the big bore smokers. kawi was not as bad as the hondas
I have had it aslo on some street bikes but on the honda 500 it was life changing
my 690? nothing to even think about even on grooved pavement it wanders but no slappers
i do set my sag and use correct spring rates but run very dirt oriented tires always and usually at 17 psi and many times worn completely out...........im cheap ...what can i say?
Maybe the new tires (with much deeper tread depth than your old ones) grab the rain groves more causing the wiggling as the tires try to follow the grooving. I have the same issue with my 2010 which also has a Scotts and relatively new tires. I ride on these highways just trying to trust the front end and tolerating the wiggling. It is annoying.
