both are basically the same around 65 miles stock.
instead of speed you should be considering suspension and handling to judge what bikes better..... in those cases, id ride the honda
hey idk if u got that off a site or what, but if you do the math assuming the bikes hit their rev limiter at 13500 then they go around 85mph. now i know they you very lucky if you hit the rev limiter in the top of 5th but thats wat you get using math.
no i didnt, i happen to know that a stock 250f goes around 65 miles, a stock 450 goes around 70 miles, the bike ryan capes jumped 265 feet with ( before the 300) went about 85 miles an hour, perfect jetting, tires, weather........ people say there 125s go 80 mph.... mabey down a giant hill, perfect jetting, with a small rocket attached to it
a 250f is going to be way faster than a 125
the engine on a two-stroke works twice as hard until it hits its point then it decels faster (over-rev)
the 250f will coast forever on 5th gear and they will keep up getting speed untill they finnally hit 11,000rpm which the crf250r has
well, i can teach you how to do the math so u can find out how fast yur bike is really going. so lets start with overall gear ratio. my rmz250 has a primary reduction ratio of 3.35:1 (this is crankshaft to basket ratio) 5th gear is a ratio of 1.052:1 final drive ratio is a 13 tooth sprocket to a 49 toother giving me 3.769. now to find total ratio we multiplky those all together which gives you 13.28:1 for a total ratio. now wheel size. i run a 19 inch diameter wheel now to add the tire thickness. so we will take a look at the aspect ratio (those numbers that are like 120/90 on your tire) the first number is how wide your tire is in mm and the second is the percentage of the width translated into height. so in other words my tire is 90% of 120mm tall, which is 108mm tall. now thats only one side of the tire so you have to double that number since we want the diameter, so we get 216mm. now we need to convert 216mm to inches which is 8.5 inches. i used google. now add that to the 19 inches giving you a total diameter of 27.5 inches. now we need to find the circumference of the tire(the total distance around the tire) the formula is pi*d. we will aproximate pi=3.14159. so now 27.5*pi=86.4 inches around the tire. now lets assume the engine in my rmz250 hits the rev limiter, i know it doesnt in 5th but it will come real close. my rev limiter is at 13500 rpms. so 13500rpm will be geared down 13.28 times. so divide 13500/13.28=1016.6rpm. this is how fast your rear wheel is spinning. now we know that it spins 1016 times in a minute so lets multiply that by our circumference of 86.4 inches. 86.4*1016.6=87825 inches per minute. so we now know that the tire is covering 87825 inches every minute. now we need to convert to miles per hour. lets multiply 87825 * 60 because 60 minutes are in an hour so it will cover 60 times 87825 in an hour. 87825 * 60= 5269501 inches per hour. now we need to convert to miles so we first divide 5269501 divided by 12 because we need to convert to feet first. 5269501 / 12 = 439125 feet per hour. now to convert to miles per hour. 5280 feet are in a mile so we divided 439125 / 5280 = 83 MILES PER HOUR. well now that you know how to do this math go try to impress your friends or something and never worry about guessing at the speed of your bike because the manufacturer will always tell you this information. well ya cant argue with the facts. and for all you skeptics out there, lets say im having a really bad day and my bike is running like crap and tops out in 5th 2500 rpms lower than normal at 11000rpms the speed is still 68 MPH.
also remember this wont works for everyones bike setup. i run a wider rear tire with the same aspect ratio making it slightly taller. to compensate for this i run a 1 tooth bigger rear sprocket. this means that my bikes gearing is stock. not that anything else is lol. full yoshi tri-oval exhaust, full renthal chain drive including superlightweight rear and front sprockets, tag tripple clamps, twin air of course, tag bars, and wavy rotors. ya she hits the rev limiter in 5th.
i have a crf250r and i have clocked it at about 75mph im not sure how fast the kx is but i a magine there about the same maybe the crf by a lil but i think it would depend on who got the better start
well actually i do know this....
the (acording to transwolrdmotocross)crf250r weighs 203 pounds, 37.5 horsepower
the kx250f is 209 pounds and 37.6 horse power but they also mention that the kx250f keeps on pullin like crazy it also won the shootou
see i just bought a brand new crf 250r about 1 week ago havent even ridden it yet but i might trade it in for the kxf because my friends bought they same ones right after me
yea i know the suzuki is pretty tight but im going to keep my crf 250 i already ordered radiator braces, skidplate, renthal grips, fork bleeders, airfilters, graphics kit, jet kit, and carb kit
but the suzuki does push more horse power out then all the bikes now
both are basically the same a

Scars mean nothing without a sweet story.

check out the new rmz250 also
check out the new rmz250 also, suzuki put a lot of effort into it.
i agree
yea i know the suzuki is pretty tight but im going to keep my crf 250 i already ordered radiator braces, skidplate, renthal grips, fork bleeders, airfilters, graphics kit, jet kit, and carb kit
but the suzuki does push more horse power out then all the bikes now
