Considering buying a Yamaha YZ250? At this point in my dirt bike riding life cycle of over 45 years I have purchased a lot of cutting edge dirt bikes. Sometimes this leaves the new owner working some of the bugs out of a fresh design. With the YZ250 you are getting a completely sorted out motorcycle with plenty of dealer and aftermarket support. if you want to ride/race dirt bikes on a budget this could be the bike for you.
For the average sportsman racer from beginner to expert, you really need to ask yourself what you need in a dirt bike. The YZ250 offers plenty power across a broad range, modern suspension, great handling, and it is very easy to own and maintain.
For motorcross and GP racing just add gas and go. All you have to do for desert or cross county racing is just bolt on a few items like a large fuel tank, skid plate, hand guards and a spark arrestor and presto! Instant XC motorcycle. Most riders could make the change from MX to cross county bike in an hour. To my way of thinking, I just want to go riding as simply and worry free as possible, I see the YZ250 as the Swiss Army Knife of dirt bikes.
