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.

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.

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?

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).
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.

it's odd to complain about a problem and then get bitchy when you don't get the answer you want to hear...

pick one...

Tires, air pressure, sag, suspension set up, steering head bearings and in some cases....the rider

I trail brake in the loose stuff, it's amazing how a little bit of rear brake settles things down.

I think the latter is more likely the only thing i havn't checked
