I was wondering, how reliable is the WR400f compaired to other 4 strokes?

Reliable as a claw hammer!

Very Reliable and can be a very powerful bike when hotted up. I have put endless amount of perfomance parts on mine for example pro circuit exhaust sytem and it goes better,quicker and is just as reliable

stock as, my 400 is as fast as the 450's but power is a bit peaky, less bottom end.

Reliability.. not a problem...

My WR400 always starts first kick, and gives me all I ask for in the trails. Tops out at 85 mph on a straight. I keep it maintained and I think it has been a great bike!
