Here are some very important Yamaha YZ250 specifications. The YZ250 pictured here has a lightweight and powerful liquid cooled 2-stroke 249cc engine with reed valve induction intake technology.

Jordan Kraft of Oklahoma owned this awesome Yamaha YZ250 and he ran this 2-stroke motocross race bike to it’s fullest potential squeezing every ounce of performance this legendary Yamaha MX bike had to offer. Jordan now currently races a Yamaha YZ450F 4-stroke motocross bike. Hopefully you’ll see it here very soon.

The Yamaha motor engineers created the YZ250 to have a super critical compression ratio of 8.9-10.6:1.

The fuel capacity of the YZ250 is 2.1 US gallons. This Yamaha MX race bike requires the mixing of high performance 2-stroke pre-mix oil with gas to properly lubricate the top end and bottom end of this efficient engine design. Yamaha produces high quality 2-stroke oil called Yamalube 2-R and is used by top racers.

The Yamaha YZ250 has a long history of performance in the motocross world being the only Japanese 250cc 2-stroke currently being produced with a high level of performance. The first Yamaha YZ250 was introduced to the 2-stroke motocross racing market in 1974 and the motorcycle racing world has never been the same. This incredible off road racing machine has been manufactured since those early days to be at the highest level of performance with cutting edge technology that has never been matched up the the current model that can still be bought today while all other 2-strokes have been phased out.
