I feel I have to reply to this thread as I have a bit (A TON) of experience with moto/ offroad. I raced the ISDE last year in Chile and spend the majority of my time (almost every weekend) racing. If you are looking into a used bike in that price range, DO NOT buy a four stroke. Esp. a Honda. They are by far the most unreliable bikes on the market right now. They have the best fit and finish for sure and you can make a very used one look really good, really easy. Their problem comes in the top ends. Once your valves come out of spec, they will forever be a problem no matter what you do. Cut seats, stainless valves. 450 and 250. The valve will fall out of spec. Yamaha has by far and away the best quality and longest lasting fourstroke right now. The rest of the manufaturers are getting better, but Yami is still #1 in dependability. My recomendation, especially being your just getting into off road/ moto is to buy a two stroke. 250s will get you your best bang for your buck. All brands are pretty good. 125s are a dying breed and tend to be more abused then their big brothers. Don't listen to the BS on how unreliable two strokes are. Plugs don't fould because it is a two stroke, they foul because they are jetted wrong.... Plus two strokes are WAY easier to jet if you need to change something. Top ends on 250 will generally last a full season under race conditions if properly maintained. Oiled filter, good gas, good oil) As far as fourstrokes go. These aren't sleds. These engines are getting super hot and ingesting dirt no matter how well you maintain them. Fourstroke bikes are not on par with fourstroke sleds as far as reliablility goes, period! Any 2003 or newer two stroke from the big five is going to be fine. Top ends are easy to do on two strokes as well. If you do go the four stroke route. I would get a Yamaha if you go and get a 250f or go with any of the big five minus a Honda, if you go the 450 route. If there is any more advise you want, I will happily give it to you. By the way, the ISDE is a six day enduro, in which the rider is the sole mechanic on his bike, no one else can touch the machine. Each day consists of up to 200 miles of offroad and can last up to 10 hours. You couldn't pay me to race a fourstroke in this type of reliability event. We tourtured our machines day in and day out with very little maintenence.
