As mentioned I have front hubs for all KLE400 & KLE500 as well as all KLR650. I can colour match it to your hub if you want this, most of my hubs are flat black (KL650A / KL650E).
The price for disassembling your wheel, cleaning the spoke and nipple threads and building a new wheel depends entirely on the condition of the spokes. It could be anything between R 1,000 and R 2,000 and more depending on the amount of rot and on optional extras like cadmium plating of the spokes and nipples.
A new front rim (Excel) for a KLR / KLE currently is R1,505. A bent rim will never be 100% after straightening and re - lacing it. There is always a (good) chance that a straightened aluminium rim will develop a hair line crack. Any damage which goes beyond the shoulder and into the bed of the rim is generally beyond repair.
