It is easier if you do. You can always leave the forks in tact. If so you have to remove the wheel and axle, then take the dampner bolt off with the crushed copper washer and drain it from there. You can't reuse that copper washer. To answer your question, Just take the forks off. Once you take the wheel and axle off there are just two pinch bolts on the lower tree that need to be unscrewed in addition to the front fender bolts. Then the fork slides right out. Much easier that way. If your going to change the oil, get the rebuild kit and do the seals and bushings also. $60 kit for 41mm forks. Not hard at all to do. Good luck.
