Modern 327 vs Modern 450.

Pre-high five to the reputable media outlet who includes the KX327 in the 450 shootout.  I don't think anyone expects it to win but back to back reviews would be cool in a shootout format.

not going to happen.....it will be compared to YZ300 kit, KTM/Husky 300s and possibly the TM300. i suppose there is a chance it could be compared to the KTM/Husky/GasGas 350s

If one of the mags does that they might anger the powers that be and lose some ad money....

Sorry brother but if you expect a 327 2T to outperform a 450F for MX racing then I have to question your judgement. 

And I say that as a huge two stroke fan but facts are facts

When can we expect a video of it? 

Will anyone spin laps on it at Loretta's? AC?

If a KTM 300 SX is not included, why would the 327? 

I would like to see lap time comparisons and some race reports though.  New CRF450R or KX327? Decisions!

It probably won't be that far off from a 450 as you think.

As a woods rider, a bike with the low to mid like a 300+ 2 stroke is sex.  Ripping a gear high, with the chassis and suspension not all bound up is an awsome way to haul ass.

The 250s do it for me too.

I have had both at the same time for years now. Different brands and sizes, but have had both a two and four stroke in the stable for at least 20 years now. Two strokes are more fun, four strokes hook up better, just my opinion. A two stroke "feels" organic, a four stroke "feels" mechanical. It is ideal to have both if you can.

The six speed on the off road bike will absolutely help it get up there with a kx450x. But the bike is not a 350 why? The answer is that model likely was too close to comfort to the kx450. Notice Kawi went looking for more power on the 450 update also.

I race my yz250 and yz450 on the same day and same track all the time and my lap times are the same. Sorry brother but it’s the guy twisting the throttle not that bike that matters.

Give me a kx327 and a kx450 and I’m running the same times.

Without any doubt, totally possible.  All about the rider.  Ask Kenny.  People shitting on the yellow bike, certainly put in their place.  That bullshit has stopped.  Put the right guy on the KX (Not Sexton or Prado).   Wouldn't it be interesting, if somehow, Kenny ended up on it for 2027... that would be fun!

Sounds like a fun bike to ride - but not sure of why they built it.  Cant Race it against the 250's and cant race it against 450 or 250 2strokes.  So maybe great for weekend warriors and non racers - but what is there reason behind it?

For off-road to compete against the 300’s and for vet mx riders.

The sad reality is that the powers that be say a 250 2t is in the same class as a 450, yet if anyone put the two together in a media shootout, everyone would laugh.

You gotta wonder, out of all the bikes sold, how many actually get raced? I'd say very small.  Just everything with racing is kind of not so fun any longer.  Costs, especially, traveling, entry fees etc. etc.  Plus, all the waiting all day for 'your race'.  More fun at your local track, buddies.  You can have little battles with ya mates, and ride when you feel like it.  I'd really expect, 10% of new bikes sold, actually line up on the gate.

Weege mentioned you could ride it against 450s in amateur mx. But I couldn't find that in the rulebook. Seems like they quietly made it 250 2 stroke vs 450?  Anyone have an answer what the rules say?  I always thought it was funny, that the mags are supposed to be for the buyers and local racers, not for the pros.  But they never put 250 vs 250 in actual shootouts back when I know that was allowed. Just one off ktm vs ktm or something

Yeah, put somebody fast on it.

Industry figures here in the UK show a migration away from racing, plus VET Racing is usually open class and that is going to be the target market. Id say its a very clever bike for Kawasaki to relaunch into 2 strokes, not many other bikes, the only Japanese offering.

As far as high level racing, those guys dont buy bikes. I dont Kawasaki even considered it as a target audience this is an out and out hobbyist bike for those who want a change. I think they will keep year 1 production tight and theyll sell out too, pretty intelligent by Kawi to offer the weekend warrior a bike that possibly gives them 2 stroke fun in a capacity they can cruise around on

There are tons of bikes being raced but its off-road, same reason Kawasaki made an offroad focused two stroke. Over 1000 people raced GNCC last weekend, not even counting the youth riders that raced Saturday.

I've ridden the Beta 350 smoker and there have been comparisons of that bike against its 450 brother. 

Lap time to lap time on the MX track, the modern 4 stroke is the superior bike. It's the physics of the every other power pulse putting that power into the ground and how far it can pull each gear (rpm).

Fun time to fun time the two stroke almost always wins. What makes a bike fun to ride on the track is what makes them slower in lap time. Its the raw feeling of having to work to put that power to the ground, shifting precisely to keep that power up, etc... that makes it fun. But it isn't faster to have to ride that way over a moto.

Yep.  If i rode mx exclusively I would be on a 250f or maybe a 350.  

Everything else i find the 2stroke to be much easier and for me faster to ride.

So, they said late ‘26, so we could be looking at Oct-Dec.120 (ish) days.

Consider this:

In the days when the AMA screwed up the rules and allowed 4-strokes to have too much displacement advantage, the prevailing thought was that a 250 would line up nicely against a 450F. (And honestly, that was pretty accurate and a much closer equivalence than 125 vs. 250F.) In later years, as the technologies have moved forward, the thumpers have gained HP numbers at a much greater rate than 2-strokes did. The 2-strokes were, after all, already near the top of their development cycle. Even considering the new Kawasaki is fuel-injected, we cannot assume that it will be significantly faster on a technology basis than a carbureted 327 would have been in 2004. We're talking mostly about displacement here. 

In my mind, I still think my 250 is an only slightly-underpowered match for a 450. Far closer than, say, to a 250F. (We're talking stock to stock here, not a Star 250F or anything.) With that in mind, a 327 may honestly be close to equivalent. 

In reality, I think peak HP on a well-tuned 327 may end up being close to or even greater than a 450F, but the area under the dyno curve will still be far wider for the thumper than on any 2-stroke. The 327 will reward good riders, but even they will have to work harder to make power than their competitors on 450Fs will. Still, those of us who still like the handling and power delivery that a smoker provides will be quite happy.

Perhaps the reason for the somewhat random 327cc displacement EFI twostroke is an AMA displacement  rule change we don't know about.  

Raise your hand if, for some reason, you'd hate that

I would like to see lap time comparisons and some race reports though.  New CRF450R or KX327? Decisions! 

I'm faced with the same dilemma myself.. Get the new 2027 Kawasaki KX327 or get that awesome new 2027 Honda CRF450.. I'm like you I want to see ride reports on the new two-stroke and the new Honda before I make my decision so it looks like I'll be probably waiting to at least the end of the year before I buy something new!

Well in the annals of amateur motocross racing all across this great land of ours the 327 two-stroke absolutely will be allowed to race the 450s and 450 A B or C.. and any other open class.. like open A Open B Open C or open beginner class..not to mention all the vet classes so there will be plenty of classes for this bike to compete in in the amateur ranks all over America!
