2020 Yamaha YZ450F Dyno

We put the 2020 Yamaha YZ450F on our in-house Dynojet dynamometer to find out how much power the bLU cRU’s flagship motocross bike makes.

2020 Yamaha YZ450F Monster Energy Edition Dyno Test

Whoah there bud my 2020 yz450f stock has 60hp

[davehouston]

You guys should put a WR450 on the dyno.

[gioevor]

yeah.. of course.. come on, next year 39hp.. like 250 !!

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.

La Yamaha YZ 450 corre bastante eso hay que admitirlo es algo peligrosa pero se da a gusta y encantar

[Blueovalnation]

What tune was loaded...makes no sense that this makes lower numbers then zook

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

I could hear its lack of power. Is it the anti smog crap, or are they getting weaker?

[toadinthehole]

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.

[weekendwarrior]

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?

[powersportsenthusiast]

only dyno numbers ive seen lower than the suzuki

[swemx]

I've allways been a Yamaha guy.. but this year i pass.
I think i will try Honda. And nope.. never going with Kawasaki.

[antisocialslimee]

This can’t be right they said it was 58.56hp?

[footbrakekiller]

Why are they low in Hp around 55 at the crank

[eldariys]

Как 49 лошадок если от производителя 57???

[bernardmandic]

It's sad to se that numbers... Cause my yz250f 2003 had 42hp

[swemx]

Fucking hell. Even my 2002 Yamaha yz426f has 47, 8hp. Wtf happend to your 450 Yamaha?

[commantrosexetlos]

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

[dr.hugog.hackenbush]

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.
