Yes. It's always been a bit of a mistatement to say 125s 2ts were particularly high revving.

Here's a first generation (2002) YZ250F vs YZ125 chart. HP Peak at same range with more over-rev on the F.

14,400 RPM redline...thats insane. What did 125 two strokes redline at?

One thing I cant help but comment on is the weight. Even if it has a KTM like powerband and power its still carrying around 10 lbs extra compared to the KTM/Husky. Where is all that weight lost at on the Austrian bikes?
2strokes dont redline, unless you speak of the new enduro fuel injected KTMs, as a carb engine rev as long as there is fuel and air increasing

Haha

I can understand why they recommend it on some bikes, as they can be geared pretty tall, like most 450s. But I’ve always felt that was going backwards on a 250F.

That thing sure sounds nice. It has that grunt just like the yamaha's. I like it.

Checked out the video on racer x. Seems like it's only got power up sky high in the rpm range as they went on about that quite a bit, similar to KTM's engine. I was worried I'd regret not waiting for the Honda to hit showrooms, but as a guy who likes more linear power with good bottom and mid out of a 4 stroke, I'm happy I went with Yamaha. If I wanted something that only makes power when it's wound out, I'd rather ride a smoker.

I'm sure putting on a 49 rear sprocket will make the bottom end feel better, rev up faster, get it feeling more like the 16/17 which has a 49 stock. The 48 hurts bottom end power feel and helps the top end.

250Fs need to be screamed. Shortening up 2nd gear so you need to get into 3rd sooner usually isn't my go to on a 250F... I'd be looking into Slip-ons, powerflow kit, remap etc. I'd bet this bike will probably scream with a 14.5:1 compression piston, a remap and some race fuel.

Ya I agree. I'd try some remapping first, the exhaust won't be cheap and I wonder how much gains will be had, hopefully Honda made it fairly light and not restrictive. I guess what I meant is if someone is using the bottom end alot, slower rider, then a gearing change may help. I didn't prefer the 49 on my 16, I went with taller gearing, 270 kit, exhaust and remapping.

I know through the grape vine that early testing at Geico FCR found the standard exhaust pretty hard to beat as you'd expect with something so intricate, but got some good results from good fuel, a Vortex and mapping and head work. Higher compression will def help with more low-mid. I'm sure there will be some cams developed too by the aftermarket that will boost the low-mid at the expence of a lttle of that big top end. This engine has a lot of potential but is always going to be rev happy with that bore x stroke.
So in saying that, if you have a limited budget for stuff after initial purchase opting for a Vortex with FCR developed mapping and good fuel before the slip on or full system. Try the extra tooth also. Especially for tighter tracks. That's a very cheap mod. Got to laugh at MXA still though for that

I'd have to agree with you on that point , I've got both and the ktm fit and finish, build quality and even reliability is spot on !! Anyone that says different has never owned the KTM.

KTM may want to beef up the transmission gears. I know of several 16 and 16 125's and 250f's with broke trannys.

Why do they even bother to paint the engine cases? They look like shit after 10 minutes...

Sounds promising, especially since an ECU offers way more bang for the buck than any exhaust and doesn't lose value when you want to sell it.
It might be a good idea to get the stock mufflers hard-anodized or cerakoted right after purchase.

It will likely be based on the 17 450, as to whether its as light as a KTM or has EC as standard no one knows yet....mind you the '17 version is only 3 pounds heavier than a KTM, so not as though its a massive difference
Correct me if I'm wrong kiwifan.
