LC4 Rear hub with Excel Rim
 
Yo,

Anyone here had success lacing an excel rim onto a LC4 rear cush drive hub?

Ive got a guy trying to do it with new spokes made from the origional as a pattern and he's telling me that the rim isnt "compatible" with the hub.

Don't know whaqt he means by this until i go and pick up the bits but wondered if anyone here can tell me otherwise??

Cheers,

Mat

Number of holes? Drilling angle?

Check out Woody's Wheel Works thread.
 
Hiya Mat,

Check out Post # 625 on the below thread.

Woody and I did quite a bit of work in presenting some pictures of rim indexing. My 640 Adventure has Euro indexed rear wheel and Jap indexed front wheel. To confirm what your bike is (I'm pretty sure it'll be Euro indexed because the hub will require that and I think all the KTM cush drive hubs are the same) and then what the rim is you use the information in the thread with the pictures.

I'm going through the same hassles with sorting out the front.
Good luck.

Here's another solution for the front.

Clarifying my babble a bit.
 
I just re-read my post and I could have been a little clearer couldn't I? I haven't even had a drink yet! (Maybe that's the problem:lol3 ).

Mat, almost certainly it sounds like the standard hub on your 640 is "Jap indexed" (I know mine is) while the rim must be "Euro indexed". They are incompatible - see Woody's Wheel Works for the options.

I have a 2.5"x18" Excel black "double flagged" rim laced to the standard KTM 640A cush drive hub and so that's not an issue. You need the rim to be "Jap indexed" and drilled for the big KTM spokes/nipples, that's all.

fasteddy, your solution doesn't cut it for my application I'm afraid. A 1.85" rim is not as good for the pounding my bike will take (setting it up for the Australian Safari) and the standard Dirtstar rims don't compare to Excels for competition use. Unfortunately Excels aren't available in black "Euro indexed" to suit the 640A spoke/nipple sizes. My option seems to be to buy a silver blank, have it drilled to "Euro indexed" and then have it anodised black. (Note that the 640A uses Euro indexing on the front wheel but Jap indexing on the rear).

Thanks for the suggestions.

It appears that the lc4 cush drive hub uses a different pattern and therefore a rim with drillings to suite. Unfortionatly the excel rim i have is the other type so i now have to see if excel can supply one with suitable drillings or buy a genuine part DID one and have it re-anodised to match my front excel.

I have heard that Husky bikes have different drillings and excel have rims to suite so hopefully they'll be jap pattern and match my hub.

Jay, what is a "double flaged" excel rim, sounds like it could be what im after as youre 640A hub is the same as then one on mine?

They sure can. I have one. The drill pattern for the rear rim is the same as for my 450 EXC too so is pretty standard.

"Double flagged" - doesn't mean much other than an OEM rim will have the text ("Excel Takasago Rim") in one location each side (single flagged) while a rim purchased aftermarket has the text in two location each side (double flagged). My rear rim is double flagged but if I have to buy a silver rim and have it anodised black to match my rear I lose the double flag on the front rim. Excel do not have any black anodised rims that are undrilled (blanks) in the US. I'm looking around here in Aus.

Whoa, i think ive got it now. You see, i ordered OEM rims from the new 690 Rallye as they're black excels. The front rim laced up fine because my 660 has a talon hub as standard. The rnew ear rim however was wrong so i thought it must be my hub that is the odd ball. However, if you say that the lc4 cush drive hub (like on my bike and on yours) has the same drilling requirements as the other ktm enduro hubs then it means that its the 690 hub thats odd and therefore all i have to do is buy an excel to fit a "ktm".

Thanks for the help. I would really appreciate a photo of your 450's rear wheel to double check what ive said is right.

Thanks loads bro!

Hiya Mat,
I don't have a close-up photo of the 450 handy but I have the front with a clear indication of how to determine the indexing. The rear of my 450 is the same indexing as the front so "Jap indexed" at both ends. I could get a photo of the rear tomorrow if you need - I might have to wash it first though, it's covered in crap!

You avoided the drama's I'm having with my front by having the Talon hub. I thought about going that route too but I like the redundancy of ICO pickups I have by using a disk mount bolt hole on the rhs of the wheel. I understand that Talon do not do a double disk hub to suit.

The following picture is extracted from the link to the Woody's Wheel Works thread that I pasted in my earlier post.

This picture is of the KTM 450 EXC front wheel.
The four 'Blue' spokes make up the sides of the two 'Tepees'. Within each of the 'Tepees' is a spoke heading to the LEFT. This gives me a "Jap" pattern index for the front wheel of my 450 EXC.

when it points toward the right you have the euro drill pattern,,,,

Thanks for that, and no need to get the photo of the front, I can see now where i've messed up, thanks!

Re : what you were saying about the Talon hub. It seems a shame to give yourself headaches just to have somewhere to sick a magnet. Below are a couple of thotos of how they incorporate a magnet on a Rallye, just incase it might help.
