OK, I just noticed something with my dirtbike. ('01 WR426) While I was parking it today, I noticed that while holding the front brake, I can still push the bike back and forth a bit. This is my first dirtbike, and I've never experienced this on any of my street bikes. At first, I thought that I wasn't holding the brake hard enough, but when I looked, the caliper was holding the rotors pretty solid. In other words, the rotor wasn't slipping when I pushed or pulled the bike. But, the front wheel still moved back and forth a bit. It wasn't due to the forks compressing. I know what that feels like. The front wheel definitely had some movement. I've never had this problem with any of my bikes before. Does this mean that I have to replace my front wheel bearings?
