High fender kit for new 640 ADV

Where can I find a high fender kit for my new 640? I have seen a few guys in ADVRider with them but I can't seem to track down a vendor in the States. The only ones I have seen for sale are at Sommer for 250 Euro. Has anyone had any luck ordering from Sommer with prompt delivery? I checked out the searches and no one has mentioned doing business with Sommer in the US.

Thanks

some of the aussie fellas will chime in sooner or later, or you can check the 950 forum. but you can get a number of versions of the high fender (stock pre-04 high fender, rallye fender (probably the best choice), or supermoto fender (creeper put the acerbis model on his 03) from many vendors - just search for "ktm parts" and enjoy.

The next thing to do is ditch the extra disc (only useful if you lug lots of weight 2up/luggage on lots of mountain passes); much easier than trying to route a second line from the top I would guess. You would need a different master cylinder for one disc and others have sourced that elsewhere.

Oh and a plug for the crossover port.

I've been wondering....

I don't have a 640 Adventure, but I plan on changing that one day...

Regarding the dual front disc setup, I can obviously see why the crossover line needs to be dealt with when changing to a high fender, but why remove the 2nd caliper and hinder braking? Why not lengthen the crossover and add clearance between it and the wheel? My 1st assumption was expansion from a longer line would cause mushy braking, but I tossed that one out... How about running two lines from the master cyl?

i am no brake expert so point your mechanical questions to others. here i am just parroting what others have done and spoke about on the board.

in regards to two front rotors... are you sure you really need two? what makes you think one is "hindered"?

My questions were just general inquiries to anyone who knew... My thought on the 1 disc vs. 2 is that the friction spread over two discs reduces pad wear and allows for better cooling- also, you have twice the surface area to apply force/friction to in order to stop. Anyways... a well-paid KTM engineer decided to use the setup, why take it away?

the dual disc setup on the 640 was borrowed from the 950 (which I suppose needs a second disc for the extra 100lbs? ); part redundancy and assembly savings trumped the engineer. what i don't get is the 950 rallye bike doesn't even use dual discs...



the worry with two discs that many have is they are too much brake for the 640 off-road. like i said, the fella that said he thought they were good for a heavily loaded bike touring on tarmac, swooping down mountain passes I guess, made some sense to me with what you are saying, but most of the time two seems like one too many.

The two discs are great for reasons I cannot reveal as it freaks ChrisC out.

But... you will give it your best anyway... right? That way, I can provide a thoughtful and measured counterpoint... unless CC does first.

Twice the weight (and the worst kind unsprung and rotating)
Twice the risk of damage
Low fender is flat out dangerous for some offroad use.

When my 640 is sold, it may just ave the 950 forks on it.

And Mack sneaks in with a surprise "thoughtful and mesured counterpoint". Atta boy Mack.
