Hi, does anyone know where i can buy or get a link to "how to build/mod a centerstand for ktm 690 enduro?
I have tried so hard to find any information but i failed.

Please help me:clap

You might want to ask on the Thumpers forum.
There is a 690 thread running there.

If you don't get an answer in the 690 thread then it is very likely that it doesn't exist. I certainly haven't seen one.

Doesn't surprise me to be honest, most people buy the 690 for it's offroad prowess. A center stand usually weighs a lot and reduces ground clearance.

maby...
 
yes many you are right:D , but i really miss the ktm640 centerstand.
The weight thing i really don belive, just look at what stuff people put on their bikes, they looks more like an overloaded mule:evil than a bike.
i can spare a few cm ground clearance and if get a great C-stand.
(690e is a joke for pure enduro if you look at the max steering radius)

sorry for my crappy english, its not my 1st language.

I didnt get any answer in the 690 thread, people are more interested in suspention mods and other stuff, thats just the way it is.

I have seen som cool centerstands to other bikes, one was built like an extended bashplate when it was in up position.

I really appreciate you took time to answer anyway.

IMHO it is rather difficult to fit a centerstand on 690 due to the frame (or better, no-frame) structure in the pegs/rear brake pump area.

Just my two cents, and now I continue to discuss about suspension... :rofl

cybbe 01-18-2010 09:14 AM

haha.
 
yes there is a some problems to get it to work with the "no frame", but i have allso seen many solve greater problems than that here :D

suspension is mounted from factory!:evil
center stand is not.. ill solve it and come back ...
Maby there is no room for a centerstand with all your luggage mods hihi.:lol3

thanks anyway all of you...:freaky

If I were going to do it (probably wouldn't as I removed the center stand on my old LC4 so I could install a side-stand), I would start with a metal skid-plate (I use a Flatland on my 690) and weld up an "H" stand out of small size tubing. Then weld rod tabs to the top of each side of the H. The rods would fit inside two short pieces of tube (sized to make a simple plain bearing) which would be welded/bolted to the bottom rear part of the skid-plate. Use something simple (KTM rubber band) to hold the stand up. Should only decrease ground clearance by 3/4" as measured from under the foot-pegs.

Steering Radius 690!
 
Is adjustable.

great..
 
Sounds like a good idea! Is there any chance you could make a simple sketch /drawing of this idea? To help me understand (under stand:D ) better?, because my english isnt too good.

The bashplate i have seen, its 85$ i think... maby i can find it on ebay or so.:clap

ps. do you still use inch or have you gone to metric/mm yet?

thx.

Cybbe, this is a really crappy picture but you might be able to use it to improve the design and make $$$ on. :D

Officially we are still on inch standard, but lots of manufacturers use metric, so we have both.

Stops and Spring
 
The problem you will have doing it like this will be the stop in the down position. There will be a lot of force placed on the connection to the bash plate. If it is not sturdy enough it will deform or break loose the bolts. To prevent that you may need to place a steel backing plate on top of the bash plate to distribute the force over a greater area. Placing a stop that will not casue you to loose even more ground clearance is also an issue.

You will have to strap it up as suggested because the upper spring attachment needs to be a little higher then the pivot of the stand or there will not be enough tension to keep the stand up.

You need also to locate the balance point of the bike so that the front is not to light. This is very near the foot peg location and the center stand attachment will need to be rearward of that point.

Send me a picture of the bottom, from front and back and I will see if I can give you any ideas.

Mike,

All excellent points. This isn't my project; just a (not much thought) suggestion. The 690 bikes have a trellis frame and plastic skid-plate. There are skid-plates which extend past the pegs so one of those would be required as you note (Flatland does not). The 690 e tends to be a bit rear heavy. I just weighed mine with full tank, tank bag, rear rack with bag of tubes, tools, rain-suit, etc. and it was 159.8 (front)+187.2 (rear) using a digital scale which is 3/4" high, so the measurement is pretty accurate. Other weights will vary depending on mods. Mine is minus a bunch and plus others and I run a Leo Vince SBK. I haven't measured where the foot pegs are along the 58" wheelbase. Again, I don't want a center stand, so I hereby tender my resignation as chief design engineer on this project. :D Time for a Cigar Mike. :lol3
