Lots of bad advice to be found. Forks are subject to amazing amounts of abuse, and only work as well as they are serviced. Remember a motorcycle has 2 wheels, and not only does the suspension effect the way it rides. The main job is to keep the tires on the road. Nothing better then a panic stop, ABS kicks in, and you start dribbling the tire like a basketball. The fluid degrades slowly, and you may not notice it as much, but the difference is huge. Fork oil suffers from heat, friction, and an amazing amount of shear. As it wears it becomes thinner, and rate of flow changes through the regulator holes, in the cartridge. Shearing causes varnish to build up, and that makes sliding parts sticky. Just because you can't SEE the effects; like with dirty oil on a stick. It does not mean you can ignore them.
Yes 15K might be overkill for a easy rider, but not for an aggressive rider. Even an easy rider should go no more then 20K.....It's not like your life depends on how well you maintain your bike......Oh yea....IT DOES!!!
