What does a 1997 KX250 weigh?
1997 KAWASAKI KX250 Specifications
What year was the best KX250?
There was a time, not so long ago, when MXA test riders fought to be allowed to race the KX250. From 1997 to 1999, the KX250 dominated the charts. It was the MXA Bike of the Year for three straight years. It was a smash hit.
How much HP does a KX 250 have?
The KX250 is powered by the 249cc, four-stroke, DOHC liquid-cooled engine. This dirt bike recorded 39.60 hp at 13,220 rpm and 18.38 pound-feet at 9,440 rpm on our rear-wheel in-house dyno. The engine’s internal components have seen quite a few updates, but characteristics are very similar to what was seen in 2020.
How many gears does a KX 250 have?
5-Speed
How much horsepower does a 2020 yz250f have?
38.2 hp @
What is faster a 2-stroke or a 4 stroke?
A stroke is a motion of a piston, meaning a two-stroke dirt bike has 2 different motions of the piston, while a four-stroke has 4. 2 Strokes are generally more unstable and accelerate faster, while a 4 stroke is more consistent and has a higher top speed.
What’s better 250 2-stroke or 4 stroke?
Some quick math reveals that, in a 2-stroke, you get power with every turn of the crankshaft. But, in a 4-stroke, you only get power every other turn of the crankshaft. This advantage explains why a 250-cc 2-stroke engine makes more power than a 4-stroke of the same size.
How fast can a 250 2 stroke go?
While max speed will vary slightly based on the type of engine, a 250cc dirt bike will come in between 70-78 miles per hour. 250cc 2-strokes will be faster than 240cc 4-strokes, but only by 5-10 miles per hour.
How much power does a 250 4 stroke have?
We ran the YZ250F on our rear-wheel dyno to determine peak output from Yamaha’s 250 four-stroke motocross bike. We documented 38.2 hp at 12,500 rpm and 18.5 pound-feet of torque at 8,500 rpm.
What’s better 2 stroke or 4 stroke?
Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports.
How much HP does a 250 2 stroke have?
The basic YZ250 two-stroke has hung in at around 46 horsepower for many years, while the latest version of the YZ250f is around 42 horsepower.
Are 250 2 strokes faster than 4 strokes?
A 2 stroke can more efficiently make more power than a 4 stroke of the same engine displacement “CC”. Eventually, he starts riding faster in the woods on the 250 2 stroke because of its slight power and weight advantage over the 4 stroke.
Why are 2 strokes more powerful?
A two-stroke engine can theoretically produce twice the amount of power because it fires once every revolution, whereas four-strokes fire once every other revolution. Because of this, it has a higher power-to-weight ratio, making it more desirable for many riders.
What does the F stand for in yz250f?
In the dirt bike world the F designation has come to (usually) mean the bike is a four stroke instead of a two stroke, such as a CRF250R vs a CR250R or a 250SX-F vs a 250SX.
Is a YZ250F a good beginner bike?
Yamaha YZ250F I’d lean towards the Honda for overall ride-ability and I’d rank Yamaha a bit higher for motor-output. But when it comes down to it, both are solid and both are more-than-enough bike for any newbie.
What does R mean in dirt bikes?
The ‘R’ denotes a race bike built for the motocross track, and the ‘RX’ denotes a race bike built for the trail. If you look at the smaller CRF125F you’d know it’s a four-stroke because of the CRF prefix, the 125 tells you it has a 125cc engine, and it’s a beginner bike because of the ‘F’ after the 125.
