Sand is an engine killer.. No grip so you're constantly at the rev limiter, and the thin powder of sand that goes through your air filter and directly into your cyclinder. Avoid the sand if you can guys, and maintain your bikes a lot after riding in sand...
K these comments r pissing me off lol it’s a race bike it’s meant to be held ur supposed to rebuild them there meant to be out on a track and torn down every race those bikes are meant to be on there rev limiter that’s where there power is if u don’t want it to blow up buy a trail bike
+brent Jones sorry i mist have worded it wrong , i meant like you go out and buy a bike for 6 grand and it blows up so theres that 6k wasted pretty much until its fixed
+brent Jones heres to hoping brother ! run them in right and they go for a long while , i just picked up a 2015 wr450f abt 6 or so months ago nd she hasnt missed a beat , gytr pipe and yz450f cdi installed nd it now goes harder than ever
Jordan Colr lol no you idiot he would of overheated the bike, especially on the soft sand bike would of been Trying to hard melted piston/ overheated cause he’s not really getting any air flow through his radiators, so reality the only thing cooling this engine was coolant and In this terrain he would of needed more than just a radiator to keep it cool
had 8 bikes and this is the only one that blew 4 other guys in town with the same bike also blew the bottom end because of faulty crank seals in 2012 and 2 of thos guys are pro
2 races then a rebuild might be a option plus puting fresh oil in aswel if you run a tunned modified engine that will ownly last 2 hrs of use on track pro riders rebuild every race but idiots saying let me have it because you dont no how to ride is dumb these bikes are not built for gentle riding they are built to win races even if you need to crank out more power but reliability drops meaning pushing your engine to near breaking point just to get the power you need
Talos The King That is exactly what I said, if I go down in practice or at a race and I am not hurt, if I lets my bike sit for longer than like 5 seconds, I get yelled at in the pits. Plus, it is hard to start a carburated bike when you let it sit on its side.
He is surely one of those rich kids that rides with his friend's that just whant to have a dirtbike but dont know how to juse one. Like look people i got a dirtbike just for showing off and be like look what i can and then breaks it and say mom and dad should buy a new one for him. And his friend's will say wow dude nice
Yes, everyone knows that 14,000 rpm (modern 250f redline) is less than 11,500 rpm (250 two stroke max rpms. Even a 125 two stroke doesn't rev as high as a 250f. (excluding Suzuki RM125)
***** If "more like 12,000 to 13,000" is referring to 250 two strokes, not a chance son, that is 125 two stroke territory. On a 250 two stroke a good rider would rarely pass 9,000 rpm because the most power is made between 7,500 and 9,000 rpm. If you are referring to 250 four strokes, the rev limiters are generally placed around 14,000 rpm, although they could most definitely rev past that without a limiter, it would end with a overheated engine, and a thinner wallet.
The online stats that you are finding show where the maximum power output is at, which is usually around 12,000-13,000 , but the maximum rpms (with the rev limiter of course) is 14,000 rpms for all new 250Fs and I'm guessing the older ones also.
the guy that recorded this is probably one of those blokes whos bike blows up at 150 hours on the stock piston and oil and they just cannot figure out why
@@ripshark456 Two strokes are a lot cheaper to rebuild, but they cost a lot more in the maintenance xD 4stroke is hard to blowup, 2 stroke if you don't take care of it after every ride you'll blow up quickly.. 4strokes just need some oil drains and some cooling..(basically) it can run for hours and hours before your piston blows up. (my piston has actually 70hrs & i have juuust a little less compression than if it was brand new., try to do 70hrs with a 2stroke you'll seize before the 50hrs xD)
@@ripshark456 I love how people always assume it costs like a grand to rebuild a bike. A weisco top end kit costs 400 dollars. Try learning how to work on your own stuff and maybe it'll be cheaper.
How long an engine last correlates to how fast the bikes avg RPM is. Both 250 two strokes and 450 four strokes spin at around 8500 RPM so last last pretty much the same amount of time. That is also why a 450 four stroke has almost twice the displacement as a 250 two stroke if both had the same displacement but the manufacturer wanted to get the same amount of horsepower out of both bikes they would have to spin the 450 four stroke so fast it wouldn't last very long at all.
Why is everyone saying it’s just because it’s a four stroke… that’s so not correct all engines can blow up

Shift up and it won't blow up dumbass
thats what i hate about four strokes , no warning , outta absofucinlutely nowhere , crunch there goes 6 grand
Not 6 grand mate! Do it yourself, it is a lot cheaper

10 grand? you got ripped. Even on a brand new bike
+motorheadgreg ikr a brand new 2017 yz250f is 7600
I could hear him holding the rev limiter that's how he blew it up
+Jordan Colr No, belive it or not a bike can handle rev limit for more than half a second..

Bro your idle is wayyyyy to high Go to 0:16 on the clip and you can hear it thats farkkeedd
My bikes idle sounds the same atm. But I'm not dumb enough to go riding before cleaning the carb out
all I see is a guy dropping his bike.
Shift?
this video should be called pussy drops his kx
+Trebz your username should be called i am a dumbass and i dont know what im talking about
+Trebz hahahaha I'm dying of laughing so hard.
should not went in the sand
Sorry about that bro, but exist 3rd gear or even 2nd :/
lol if u would quit freakn revving it so damn high... :D
Fucking MORON! You don't deserve a bike.
Hahaha face plant learn to shift and you'll be surprised how long your bike will last hahahahah
my 6 year old could hit the ground harder than that and still pick up the bike. ch'mon now
Do you not know how to shift, you were like riding the rev limiter it was torture to my ears god damn
i wonder how many bikes hes blown up riding like that... probably quite a few
had 8 bikes and this is the only one that blew 4 other guys in town with the same bike also blew the bottom end because of faulty crank seals in 2012 and 2 of thos guys are pro
BRUH YOU AIN'T BARCIA CHILL WITH THE LIMITER
Shift you stupid ass , I love kawi and i ride one , watching this was like torture , poor bike , take better care of your stuff man please .
That's why you don't stay on the limiter mid air...
dude if you listen to the bike you can hear it was fucked already

pick your fucking bike up man

+Chase Hewett whats the diffrens when its still done...
treating your bike with respect
wtf hah
surprised it blu up, he dont know how to take the bike out of third gear. nice bike though man
It sounded like it was about to blow the whole time
35 degree weather?
celcius
Probably Celcius
bro. I felt that fall i promise u
Why did you not pick it up, dont just let it sit there.

2strokes are more likely to blow up, they rev much higher then a 4'stroke

rev limiter much?
Good job with your shifting you fucking idiot
maybe if youd fucking shift
Me and the Honda dude have the same Goggles
bad luck man hope u got it fixed
I got the same helmet
hahahahah suck shit
4 stroke
thats a warm 35 degree day....
problably in celcius
TheXcaliber223 *celsius
Didn't even think of that haha
That's what a shifter is for dumb ass
Good thing you wore a Helmet, glad your okay.
There's nothing wrong with Kawi, they're great bikes. I've ridden them all my life! But I will admit honda and yamaha are great too
people are so stupid "because it was a 4 stroke it blew up" or " that's why I ride two strokes" they all blow up.
two strokes are alot cheaper to rebuild when they blow up when a fourstroke blows up your fucked
ripshark456 that's not the point im getting at, every bike will blow up people are just saying because its a 4t it blew up

That's y I don't ride in sand
From the very beginning of the video your bike sounded like it was going to fall apart.
Bdo'sMotoAdventures IF ONLY THE BIKE COULD TELL YOU HOW IT FELT. lmaoooooooo
sand+dumbass=fucked engine.
And now... You buy a 2 stroke(:
Cameron Byfield 2 stroke really...they blow up more often whats your point.
you can rebuild two 2 strokes for the price of one rebuilt 4 stroke
lithium25693 but 4 strokes last longer too

Just because you can rev the piss out of a 250f, Doesn't mean you should...
then why buy one?
