I have a skid plate made out of aluminum that also holds 2 liters of water. Those two liters are the emergency water that every rider must carry and having them in the skid plate rather than in your backpack or somewhere else on your bike has its advantages. First off I would really recommend trying to put as much stuff as possible on your bike instead of carrying them on yourself. Having extra weight to carry will be tiresome when riding long days. The skid plate is about as low as you can get on your bike and it is good to try to put any extra weight on your bike as low as possible to keep the center of gravitation low. So having those 2 extra kilograms on the skid plate is perfect.
Johan doing his TIG magic
I was down at my friend Johan at Pro2 and his shop the other day to get some help to modify my skid plate since I can not weld aluminum myself. I drilled a hole through the water tank and put in a tube that I can use to get better access to the bolts when mounting and demounting the plate when servicing the bike. Everything to save a couple of minutes each day when servicing is worth doing.
Johan did a superb job and all it cost me was a couple of brews. Since Johan is also going to the Tuareg rally I will repay him in the Sahara. :)
