now i am even more confused. i have ridden a lot of dirtbikes, raced cc, and currently do a lot of practice days the local motocross tracks w/ my kid. i have a klx400r for that. what i am looking for is a good powerful dirtbike, that i can trailor places like the bigbend country in s. texas, or to carson national forest in new mexico, and ride the backroads and trails, and scoot down the highway for a spell to get to more trails. also will be using the bike for short trips around town. your opinions please? If you are going to trailer the bike and only ride on-road a little bit and want a "powerful dirtbike", then you should forget the L and R and dual sport a Yamaha WR450F. That is what I now own after having an L and R. I found out that I prefer to haul my bike in the back of my pickup to where I want to start a 150 - 200 mile dual sport ride. The only problem with the WR is that the seat is too narrow, no matter what type of foam used, to be very comfortable for 150+ mile rides. But it is a powerful dirt bike with great suspension and light weight, though not as light as a full motocross 450F. I haul my bike anywhere from 45 to 200 miles to where I start riding. Basically I like the WR450F best when I am mostly off-road and would like the L if I am mostly on-road. I have come to the point where I have no use for the R because I like the WR so much better for all the off-road riding I do.
