Here is something for those of you riding newer KTM xcf and sxf models with the large rear axle.
In my fanny pack I carry the newer KTM multi wrench. It is important for me because it has all the contemporary axle nut sizes; 32, 27 and 17mm. This particular wrench came as part of the tool kit with the 2015 450xcw I purchased. It is part number #50329080100. According to the microfiche, this part is the same in the xcf/sx tool kit.
On the last Baja trip we got a puncture on the rear of the 2016 250xcf. When I went to pull the rear wheel I discovered that the wrench is not really practical for use with the larger 32mm nut. Even though it is the correct size, the recess is not deep enough to allow good purchase on the nut. To make matters worse, the Aluminum nut has two different machined reliefs that remove material where it would be most needed with this wrench.
Fortunately, one of the other riders had a slightly different version of the same style KTM wrench, noted by the lack of tire iron end. It was just slightly deeper and worked for the situation. KTM had put the nut on good and tight and even my small Channel Locks were not going to be enough to get it loose.
This is the other version of the wrench. I cannot seem to find it on the parts fiche. But the casting quality seems to be a bit cleaner. More important, the depth of the 32mm box is 4.3mm compared to about 2.8mm on the newer one.
I am not sure if there is a better multi wrench for this purpose that will have all the sizes. For now I am going back to my old standby, taking a 1 1/2″ combination wrench and cutting the box end down to about 8″ to fit in my pack. It is not the prettiest of choices, but it is cheap and indestructible. It may be short, but I can put a boot on it without worrying about it slipping or bending.
