Uphill 400ex's suck balls. They do not have hardly any torque either. I don't care what anybody says a 350X will beat a 400ex, especially uphill, on a 350X uphill you will be in 3rd and the 400ex in second wide open and there is a good chance of having to hit first. I mean the 400ex is kind of disapointing to me, they have a 16 year old 350X that is just as advanced as a brand new 2002 400ex and will out do and is more all around more sensible to own. I mean the gearing is just to high on the 400ex. The 350X has everything the 400 has except a dry sump oiling system which I think is stupid, because then you just have even more oil lines running to possibly catch on sticks and such. I could go on and on but I won't. I also am not putting down the 400ex, but it just isn't up to par, I mean reliability and fun wise it is a great bike, but in stock and even slightly modified form it is a joke for a bike of that size.
