From 1998 to 2007 the only thing I owned was my zx11. Rain, snow, everything I road in, tried not to ride in ice though.
Now I ride every change I get, but due to the kids, and the 2yr old, it's limited, but every time I can I do.
The 2yr old loves to ride on the dirtbike with me though, she begs to go out on it.
I have never owned rain gear though. I just get wet, then try off quick enough it doesn't really matter. The only issue I have had with rain is if I drive through a puddle deep enough to get water down the top of my boots.
