If you dont ride dirtbikes hard wich one is fastest and quickest honda cr125R vs honda crf150R?

Question

Dont the racers race 4 strokes instead of 2 strokes?

But i heard the honda 2 stroke cr125R are about as fast as the honda 4 stroke crf250? Im CONFUSED

Answer 1

The cr125 is equilevlant to the crf250r with horsepower. The engine just creates horse power easier. so a kx 65 or something would be equivelant to the CRF150r. I have seen many kids shread up the track the crf150r. It's one of the best beginner bikes ever! I would choose 150!

Answer 2

The cr125 does tend to race against the 4 stroke 250cc but they are very seldom at the front unless they have a very experienced rider on them as the 250cc have just that little bit more pull than the cr125cc.  

I believe in America the crf150r races in a class of its own but in Australia they race against the 85cc class and are of comparable speed although the 150 tends to get off the line a bit better.

What bike would suit you would depend upon your age and size.

Answer 3

If you dont ride them hard, who cares what the speed difference is?

Answer 4

cr125 you cant even compare those 2 . but honda sucks by a kawasaki

Answer 5

TWO STROKE ENGINES

Cycle - Two Strokes:

1.- Compression (intake+compression)

2.- Combustion (combustion+exhaust)

Advantages of two stroke engines:

The engine fires - spark plug ignites - once every revolution of the crankshaft.

They produce twice the power than four stroke engines.

so yes a cr 125 is going to be just as fast if not a little faster than a crf 250.

Answer 6

It's true.That's why some 250 4 strokes race in the 2 stroke 125 class, and 250 2 strokes race in the 450 4 stroke class.

Answer 7

the 125 is faster than a 150 and is supposed to be the equivelent of the 250f but isnt hence the reason that everybody races 250f's they have just changed the lites/mx2 two stroke capacity level to 144 but the fourstrokes still have the advantage

Answer 8

The cr125 will smoke the crf150.....There are alot of 2-strokes still racing...Alot of it is the rider...You can take a 125 2-stroke with the right rider and smoke a crf450 on a race track....We see this all the time...

We have also seen 85s win open classes where there are 250s and 450s in them....

Answer 9

125 and 250f are suppose to be equivilent but a 250f has way more power and most ppl ride them bc of that and factorys stopped making 2stroke and only make 4 strokes now

Answer 10

here's the differnce between 2 an 4 strokes. 2 strokes power is all up top, if ur racing u can't let it get low. 4 strokes live for low power. 4 strokes are much easier to ride b/c their power is mainly low but is mid and high also. Ex say ur goin into a tight bowl turn. 2s style: have one high 2 pull in clutch, ride thru bowl let go of clutch an go, little braking allowed to keep up momentum. 4s style: hit in 3rd. That's it just ride thru it. If the same person rode a cr125 an a crf150 the 125 would murder.
