KTM 640: Alternative front rim solution!!

Most all of us know by now that the stock front Behr rim on the 2004 & up 640 Adventure is made of putty. I figured that before it failed completely I would take the opportunity and get myself a set of excels front and back. An e-mail to Woody, a transfer of funds and presto problem solved.

My plan was to use the new Excels exclusively offroad and clad the stock rims with more streetable tires. I went through 6 rear knobbies last year and with this setup I could minimize the use of knobbies on the pavement. Unfortunately it became apparent very quickly that the stock bent behr rim was just to far gone.

I almost ordered another Behr rim, then got to thinking why replace that piece of crap with more crap. Another Excel would be great but maybe I could cut the cost a bit with another solution. Using the OEM parts finder at www.ktm-parts.com I started to compare part numbers, specifically spoke sets and found to my surprise that the front Dirt Star rim on the 950 Super Enduro would lace right up using my existing spokes. I ordered the rim. KTM Part: FRONT RIM 1,85X21"DIRT STAR 06, Part # 6300907000030 and to my good fortune it wasn't backordered!! A buddy laced it up for $40.00 and now I have a new wheel for street use. I have a feeling that this wheel will also handle offroad duties if called upon.

Here's my 640 clad in street rubber!! Note the new Renazco seat as well!!

Your 450's front wheel would have worked as well.

The idea was to do this a little cheaper, although the spoke pattern on the rim on my 250/350 ( a 250 exc with KTM's 350 Hard Parts kit) is the same as the 640 the spokes are different, much thinnier in diameter. It would have mean't drilling out the rim spoke holes to allow the original spokes to fit. I also wanted a bit of a wider rim for road work and the 1.85 size of the dirt star rim was a good compromise when compared to the extra wide stock rim and a 1.60 Excel.

Only pic I had of the wheel was before I removed the one disc (common mod for the 04 and on 640"s) Actually I've used that disk on the spare wheel!
