I still think 450SX has a nice ring to it.
Of course the four Japanese brands would squeal like pigs if anyone tried to do a comparison with their 450's.
Would be cool, just for that reason alone.

so why would they put a 300SX into their lineup when they already make a 250sx with the same chassis and they sell a 300 SXS cylinder for sub 800$? i wouldnt think they would release a bike thats just an assembly of the parts they already sell? that wouldnt be much of a 'release' would it?

granted, it would save someone a couple hundred bucks of converting it themselves and save them a half a day of work.

i'm 6'4" 250# and the 300SX has gotten me in a couple of nasty situations. the thing is stupid fast. i wonder if them releasing something bigger cc than 300 is even really feasible to the public?

going to be interesting to see where this is going.

JBernard, I haven't ridden a 300 KTM but I have to imagine it behaves more like a 250 on steroids rather than a traditional open bike. The beauty of the old 500 two stroke was that you lugged them and rode a gear high for the most part and respected the power you had at your disposal and only turned it totally loose when the situation was perfect.. Also my old 500CR was one of the most reliable and versatile bikes I ever owned.

edit: just looked at your sig more closely and saw your KX500af project, did you ever finish that sucker?

I am no engineer but i think you could build a 2 stroke motor in the 350-400cc range with a heavy crank that would have an almost 4 stroke like powerband. I like the 200 for the woods and 450 4t for mx but something like this might be cool on the track.

youre right on the money there.
me and my buddy bought our 14 250SX's at the same time, now mines a 300SX i can easily compare it to his. and another friend has a 91 CR500 ive ridden.
the 500 of course likes to be ridden easy, a gear high, and rolled on the throttle. my 300 is a screamer. of course, it can be tamed down with green PV spring, 36mm carb, and a flywheel weight to be way more tame. but it will never come as close as a 500 to luggable.
still working on the 500AF! but will update that thread tonight, have some cool new parts. Sadly im doing so many innovative crazy things to that project the timeline is huge, but i'm trying to get her wrapped up!

Since we are all giving it a go here and KTM is stepping it up here's my wish list in addition to what they already have:

200 SX
300 SX with kick and estart
380 SX and XC with kick and estart
500 SX and XC with kick and estart

If you are going to rub it in about your growing ratings and sales in the market and how popular the two-strokes are why not show the Japanese manufacturers how big the wish for open class two-strokes are as well.

We can always dream.

i dont even want to know what kind of power they could put out with current technology and engineering into a 380 to 500 2 stroke. it would be insane.
the engine in my 500AF is TWENTY FIVE YEARS OLD and should be putting north of 60HP and do a top end every 5 years haha. just think about that for a second.

The idea is to build a 450F competitor. The 293cc KTM isn't really close. For one it's 8hp down and had a comparatively narrow powerband.
A softly tuned 360-425cc 2 stroke fits the bill.

8hp down? i saw a ported 300SX on race gas put down 60hp on the dyno in AUS.

The Ktm300 has this legendary status around here but I've been riding them for 6 years now and they are not all that. They don't rev right and they aren't all that fast.
I have a fully built 314CC KTM now and it runs like a strong 450 (dyno verified) but I'd prefer a factory built large displacement bike that doesn't require 116 octane to make the power and stay together. Plus I want the new chassis.

I would love to see a modern 450cc 2-stroke. There's an entire generation that believes 4-strokes are faster on a cc-per-cc basis because they simply haven't ridden a smoker.

A 200sx would sell like hot cakes.. I had a 2003 200 sx that was awesome, and currently ride a 2013 150sx with a 200 motor in it. I could see a 300sx maybe. Not sure who they would market it to... I guess vet riders with no cc restrictions. But then again a 200 sx doesn't really have a mx class to race in either...
+25, +30, +35, etc.

You know, age groupers who have the $$$ to spend on the sport.

My wish list would be:

Keep the 125
Replace the 150 with a 200
Replace the 250 with a 300-350 and then lobby the AMA to allow the displacement into the 450 class. Same with the 200, try to get it allowed in the lites class. Let's face it the 250t is pretty much classless now days.

Ok...it's 820cc, has a hybrid "two-barrel" carb and a 3 speed tranny with autoclutch.

They are faster around a track for the average joe.

the 97 360sx was a great mix of near 500 power and 250 handling (compared to a 500 anyways)...give me a 399SX and I'll sell off my 250SX no problem; bring it on, KTM!

That opens the argument why do they make a 250XC, 250 XCW, 300XC, and 300XCW?

I would ride the living hell out of that bike! I sold my 250f after riding 10 minutes on my current 15 250sx. Big bore two stroke is the epitome of Man.

I know that I couldn't (ride it worth a spit). However, I would be wearing the biggest grin in the history of mankind as I goobered that sucker around the track.

I would guess at 400SX.

Would fit in the lineup perfectly.
250SX
250SXF
350SXF
400SX
450SXF

New cases, crank, cylinder, pipe. Use the gearbox from the 450 to save on new parts and you're in business.

Heck, with today's technology there are literally thousands of people that could CNC machine and/or print virtually everything to make their own big-bore pinger.

The Husky version could be a 390. The 1977-1980 era with a black gold graphics would be cool. The silver tank 500cc of 82.5 model would be another cool graphic and would decimate the jap bike companies in one swing. Americans usually buy the biggest cc bike. Build it and they will sell. Imagine a 80 hp 500cc bike weighing in at 225 pounds. Of course e start would be manditory with a 4 inch bore. Honda would just have to pack it in as they said they would never build a 2 stroke again.

I ride an Eric Gore RM295 and love it. I went 1-1 in the +30B classthis weekend and even ripped a holeshot 2nd Moto over the A riders. BUT I don't know if I could ride a 500. If things got crossed up right when the power hit....... That could be bad. I'll just stick to my 11 year old bike and have fun.
