In this case because we are talking about aluminum I will refer to (1) Casting, (2) Machining, and (3) Forging. The least expensive and least strongest method is casting. Most of the Aluminum (Aluminium) parts on the 690 are cast as this is an inexpensive and quick way to make the parts and for many of the parts the strength is adequate. The Kouba links are machines out of a Solid chunk of Aluminum (Billet)...Billet is a term that gets thrown around as if it has magical properties...people like to point out their Billet aluminum parts...but Billet just means the part started life as one big chunk. The last method is to forge the part. Forgings can be hot or cold and this refers to the temperature range that the metal is heated to before it gets worked in the forging process. Forged aluminum parts tend to be the strongest because of the way the parts microstructure gets arranged and because of the way the material gets worked during the process. Forging can be very economical but it depends on the scale of production. When you only make a few parts it is not economical.


So that said Casting is the chosen method as the strength is usually good enough and its cheap. Most of our aftermarket parts are machined from a piece of Billet Aluminiumumum.


If there is a need for an uprated link then It would make sense to have some pieces machined from a solid chunk and choose an uprated bearing. While the rally ones are nice they are pricey and still cast.

Somebody convince Kouba to make a stock length so I can buy one.

well if it serve no purpose other then looks, no point for me to swap out the original E R clamps

You can help by sending him an email and expressing your desire to purchase one.

njkouba@ix.netcom.com

Edit:

I went back and found the parts list (created by Beaney) to upgrade the 690 with rally parts.

Pull rods from 450 rally bike
Rocker arm 660 rally bike ( requires machining)
Rear shock 450 rally ( Having a custom made Ohlins ttx made giving 305mm of travel)

[QUOTE=MeinMotorrad;22476720]I hit a piece of concrete on the road at night doing about 70. I'm guessing the concrete was about 7 or 8 inches tall but really difficult to remember properly. Bike went airborne for some distance but landed straight and thankfully I was able to come to a stop without falling.

The front wheel is buckled but I can't see any other damage to the forks or steering. Should I be worried about other damage?...QUOTE]

MM,
In situations like that I later discover that my underwear has been damaged... .

Big sharp hits like that can damage steering head bearings, so try to get the front wheel off the ground and check for any notches or clicks or play in the steering.

Also your forks may be out of alignment. If you know how to check this you should or have the dealer check.

The offset is different because the forks are different. I think the steering will be sharper- you may or may not want that.

Also if you are running any steering damper, I have been told that it not work on the SMC triple trees. I'd love to know whether it does or not.

Problem is we do not know what alloy they are using.

You can easily triple the strength of a part with an appropriate alloy. Pretty easy to jump from 25,000 to 75,000 psi (707x T6) with an appropriated selection.

Drop forging will add up to 15% and extra life.

Heat treatment is critical to many aluminium alloy.

Thanks for all the advice guys.

I've been trying to get in touch with the nearest KTM dealer who is in a place called Boe, about a 60km ride from me, but no luck so far. Maybe Google translate isn't so great - pas de fumée française.

Wheels: Anybody tried these. I'm wondering if they're stronger. I've seen some Excel wheels (Wheels with hubs machined the lightest on the market. Wheel with strapping, hub and spokes. - That's the google translation), for 369 Euros but I don't know anything about them. Will I have to get bearings also? I've never bought a new wheel before.

If that is the ST-X, that is the one I have. I replaced the OEM 1.85 with the DID ST-X 1.6. Used same tire as OEM. I just bought the rim and used existing spokes and hub and relaced.

The stock rims are 36 spoke rather than 32 spoke, so if you are re-using the original hub, you need a 36 spoke rim. If you are using a complete wheel, then the number of spokes is less of an issue. You need only be concerned about axle diameter, hub width, spacers, and rotor mount.

Yes a good point. We have a tool in the lab at work that will tell the material makeup. Might be able to sneak a piece in

Hi I'm on the lookout for a new bike and at the moment it looks like the 690 with RR evo 2 tanks is at the top of the list. I will be buying secondhand so are the any year models I should avoid or be looking out for ? I see a lot of you guys are changing your exhaust. Is this just to get away from the CAT ? If so has anyone removed the CAT from the OE and welded it back up ? (I did this on my x challenge and it worked great) if I did this would the bike need to be remapped ? ( on my BMW it never) . Are the any known faults I should be looking out for when going to see 690 ? What are they like to work on ? Iv never had a KTM so it's all new to me.
Sorry for so many questions
Thanks kito

Just took my new to me 08 out for a shakedown run. Holy crap that's fun. One problem is a leaky gas cap. Maybe its all the wheelies

What is the best solution for that?

Buy a KLR if you need a solution for the wheelies.
Rally Raid & KTM Twins has a solution for the fuel cap.

I've owned a couple KLRs.. I don't think I'll be revisiting that any time soon. This thing is fun!
