Hi Gents, this reading need to be taken with a grain of salt (that is, it is just an indication). These tests are great to compare bikes under the same environmental conditions. This test is a non-dynamic test, that is, it is not representative as in an outdoor environment. Two (2) main factors are missing. Firstly, the air flow into the inlet is SUBSTANTIAL restricted as the air flow into the bike is essentially 0 KPH (just check the riders shirt), so the bike demand for air is immensely deprived. Secondly, the air/road friction is another factor. I would not hesitate to say, that given there is not sufficient air feeding into the inlet, these figures could well be 3-5% below of what the bike can achieve. The only way to get a closer Power/Torque figure would to have a variable speed fan right at the front of the bike to simulate road conditions. Notwithstanding, it is a great starting point. Love the videos. Many Thanks
What is interesting is that the Dyno for the 2019 YZ450fx scored 53.24 HP / 32.57 TQ. The 2020 YZ450f posted 48.9 HP / 29.3 TQ That means the 20 yz450f is registering about 8% lower HP and 10% lower TQ then the 19 yz450fx. I wonder how much of that is in the dyno (e.g. maybe it got a software refresh or re-calibration ) vs how much is in the method ( maybe there was some tire slip ) vs bike? Hard to believe that the off road model from last year makes 8-10% more power then the mx version of essentially the same bike but then again can't compare peak numbers 1:1 it's really about the area under the curve.
I know this is late but Yamaha might have made it less horse power for a couple of reasons like the new tuner you can download on your phone to tune the bikes power so they probably turned it down from factory just to encourage people to use the app the other reason might be for traction purposes.
They had the same results like that on the dyno between the crf450r and the crf450rx, the 450rx ultimately ended up having more torque and horsepower according to the dyno test, idk why this is
@@drivernephi5295 Oh not accurate? I didn't know dynos lied but okey mr smartass. I guess your feelings are more important then straight up facts by a dyno.
@God sees all!!! "beginner map"? im pretty sure the guy operating the dyno isn't stupid. 2nd of all you cant compare numbers from one dyno to the next. dirt riders numbers are typically lower than other publications anyway, so it means nothing
With the intakes at the front is there any possibility of a ram air intake effect at higher speed,which would in turn produce lower reading on a dyno? I see some of the(Bike It) kawi boys in mxgp run a front intake over the fuel tank, im guessing for that reason?

And the 2019 yz450f had 50 hp which is still lower than the fx

It has 18 inch wheel and wider gearing so obviously it’s gonna have more horsepower on the dyno
I think my 2018 is making more power then that. Idk
Please next a Kawasaki KX 125 2005 onwards . Was said to have 41hp . I owned this bike and it was fast as shit off a stick.
I could hear its lack of power. Is it the anti smog crap, or are they getting weaker?
I think it's the smog crap it holds them back a lot
Euro 5 compliance destroys everything.
I think so. My stock ‘14 yz450f makes 58.17 hp on the dyno. How does the 2020 only make 48.9hp?
@@jamesdecker4166it doesn’t it makes 58 as well idk why’s up with his dyno
What tune was loaded...makes no sense that this makes lower numbers then zook
Beginner map, dirt tyres causing more rolling resistance, wheel hp not engine, multiple things. But, it is quite low
How fast does it go stock?
130 km/h
I got mine to 127km
When wr450f?
You can view that here:

I've allways been a Yamaha guy.. but this year i pass.
I think i will try Honda. And nope.. never going with Kawasaki.
This isn’t accurate so dont worry
@@drivernephi5295 Oh not accurate? I didn't know dynos lied but okey mr smartass. I guess your feelings are more important then straight up facts by a dyno.
This cant be right?
Cv?
only dyno numbers ive seen lower than the suzuki
On this same dyno, on this same channel? I believe they are measuring at the crank and not at the wheel...
@@MXJEFF94 i dont know of ANY media outlet measuring at the crank.. crank numbers, if given, are usually from the manufacturer
@God sees all!!! "beginner map"? im pretty sure the guy operating the dyno isn't stupid. 2nd of all you cant compare numbers from one dyno to the next. dirt riders numbers are typically lower than other publications anyway, so it means nothing
This is somehow inaccurate... i had a 2016 crf 450r it should be 53 hp. Now i have a 2020 yz450f and the power is much much much more.
This can’t be right they said it was 58.56hp?
This is at the wheel. There is power loss through the drivetrain.
@@Nater36 appreciate that💙
Honda all the way
lol you must suck at riding
With the intakes at the front is there any possibility of a ram air intake effect at higher speed,which would in turn produce lower reading on a dyno? I see some of the(Bike It) kawi boys in mxgp run a front intake over the fuel tank, im guessing for that reason?
Maybe youre thinking on the right way, i though the same, Ive seen this bike reach any other bike on the track really easy, so
Как 49 лошадок если от производителя 57???
yz 48.9 sxf 63...
Fucking hell. Even my 2002 Yamaha yz426f has 47,8hp. Wtf happend to your 450 Yamaha?
most of new 17-18-19 mx450 have less power than pre 2014..like my 09 kx450 stock 52.8-53 whp..while the 2017kx450 50whp
2019 crf450 has 60hp...
@@NickW90 yes she does and still on sudden full throttle old kx still feels stronger...
It's sad to se that numbers... Cause my yz250f 2003 had 42hp
This is Power on wheels. Engine Has 60 bhp
horsetwaddle
Why are they low in Hp ......usually around 55 at the crank
Wheel hp is less than crank hp
Weak sauce. My KX500 absolutely slaughters this thing on the dyno.
This seems like it revs a bit higher though. Check the calibration on the dyno.
Who has the dyno.. yeah thats right that guy, not you. Stop playing smartass and shut the fuck up.
lets see it race the 450 then
Honda does better .
Not on a track 😂
to low hp. try again))
