LC4 Rear hub with Excel Rim

[matsplatuk]

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?

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.

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 ).

he's telling me that the rim isnt "compatible" with the hub.

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.
