Accident

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?

The tyre and HD inner tube are both history.

Does a 2012 SMC R triple tress serve any purpose if I fit it on E R, well other then blink factor. Got myself a set of 12 smcr wheels comes with triple trees, suspension etc etc.

Sintered pads

I fiitted new front and rear brakepads in preparation for a rally in 2 weeks. Pads were sintered SBS as per their website's recommendation. However, after 1 bedding run, I'm seeing some abrasion on the rear disk. Are they just soft or should I consider other options.

I'm going to assume you only replaced the pads and not the disk? When you first install the pads, they don't have the same surface profile as the disk. Your old pads and break disk wore together to make a shape that wasn't flat. You new pads also are rough right now. Soon they will become polished and you shouldn't see much more abrasion.

Blink factor?


The axle is in a straight line with the fork on the SMR. On the enduro the axle is offset forward a few cm. The tripple on the SMR makes up for this difference some. Lukas can probably go into it more. Look at this thread. http://www.advrider.com/forums/showthread.php?t=698632

Yes, only the pads. I was just taken aback by the amount of abrasion on the rear disk, the front disk is not showing anything. Interesting enough, 1 of the rear pads had a lengthwise crack through the friction material. It had almost the same thickness left as the new pads.

You should pull the caliper apart and clean it thoroughly (if you haven't done that already). That condition can indicate a sticky piston on one side.

Yip, thanks. I'm doing that this weekend. Quality time!

Hitting it straight on even at that speed likely didn't damage forks or head bearings. Just replace rim-you can get one of the DID rims that is lghter and stronger than OEM. You will be good to go.

All of the links shown so far with the exception of the Kouba Link are cast units. In the world of manufacturing metal products there are 3 common ways to make shapes out of metal. 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.

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)

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.
