Thanks for the reply.

I do agree low displacement DS bikes have many disadvantages, particularly against the big displacements bikes, like highway travelling. However, the big displacement DS bikes all appear to be over 300 lbs in weight. Highway use good, tight trails not so good? Do non-beginners looking at DS bikes need displacement and then live with their weight?

Any comments others may have about how the 2006 KLX performs, good or bad, would be appreciated.
