One thing that seems to plauge a lot of riders in wet areas is sticky steering stems. The beging to collect dust, dirt and grime. Toss in a little water and the next thing you have is unneeded friction and in a lot of cases unexpected steering jerk.
The most notable sign that things are going wrong it the 'squeeking' you start hearing after pressure washing and drying a lot. This design allows adding grease after every ride to push any water or grime back out.
