I'm sorry if this has been covered already, but I ddn't find anything-I'm probably not doing something right. I'm looking to buy a late model YZ450F, but I just want to make sure that overheating isn't going to be a problem. I ride a lot of tight single track. I'm assuming that most of it will be first and second gear on the 450. Do they get pretty hot on tight trails? I've read that the WR's get pretty hot, but they have that resevoir. I don't want a WR becuase they're too heavy for my preferance. Any help is much appreciated. Thanks a bunch.
