I was looking at the videos on their site and they do appear kind of slow and clumsy. They do seem ruggedly-made and can go places that ATVs wouldn't dare. What size engine do these have and what kind of weight-load can they carry? 5-6 grand seems kind of high for these and are they really worth it, or just another novelty? What are some other choices in a rugged off-road bike? I hear a lot of buzz over the new Hayed Diversified Technologies diesel KLR650. Best Wishes! Pecos Bill out.
