a crf150r is like a rocket to a kx85 a crf150r will eat a kx 85 for breakfast!!! there both fast but i have trouble with the kx and no trouble with 150!!! So overall a crf150r runs better and is faster!!!
Over all the CRF150r is a faster bike. The 85 makes about 17 hp depending on humidity, altitude, and temperature. The CRF 150r makes 22 hp with the same atmospheric conditions affecting overall hp. The power is totally dfferent between 2 and 4 stroke machines. The 85 has a very narrow powerband not making much torque. The 150 has a much broader powerband making alot more torque than the 85. It is the nature of the 2 engine types. The 150 weighs more than the 85 but the additional hp and torque more than offst the weight advantage.
The kx 85 is over all faster......but the 150r would give it a run for its money
the crf150 i own a 04yz and i rode the crf its a crazy bike
A RM 85 is twice as fast as a CRF 150F. The RM is 143 lbs and 23.5 horsepower, the CRF is a portly 214 lbs and 12.8 hp. The CRF is a better trail bike, it is durable and will survive in a low maintenance environment. The RM must be maintained, it hates dirty air filters (it will bog) and needs a top end rebuild every 50 - 140 hours (depending on how you use it and maintain it). The RM is a tough bike and a blast to ride.
It goes about 70-85 mph
well the crf 150 will go about 55-60 and the cr 85 is faster - anywhere from 75 - 95 mph.
If you are between the ages of 9 and 14, the cr-85, the ages of 11-16 the 150r. If you are older, but just a beginner, the 250r is a good bike. For more advanced riders, the 450r. My personal favorite is the 150r.
The KTM is estimated to have a maximum speed of 60 to 65 mph. The Honda CRF 100 is said to do 62 mph on a straight gravel road. The difference is negligible and depends on tuning, sprocket size and kind of terrain.
crf 100f, ttr 125, dr z125l, klx 140 or ktm sx 85 hope that helps :p
as he is 15 i would get him a 150 crf or even a 250 if he races i have a 250 myself and is amazing on the trails and tracks
you scored 85% better than other people taking the same test at the same time
is .85 less than a mile
