With BETA having a 350 t/s and now a Kawasaki 327KX t/s - can we assume KTM will add a little to the 300SX ?

It will interesting to see how the KX compares to the KtM..I think the Beta 350 makes less Hp & torque than the 300SX ? I don’t think KtM needs to up the displacement, as their tuning gets better, they get more out of the 300…they left alot on the table with stock mapping …..I hope some other manufacturers join the party…..consumers win…

I have seen that KTM Racing the Austrian Championship back in 2025

Rumors say they Test different Bore and Stroke Options from 350-400cc

At the Moment it’s quiet around this Bike last thing I heard is that Piston breaks similar to the 300 SX

Vitalmx: 450f bikes are too powerfull we need to slow down bikes... 400cc 2-stroke would be best!

I owned a 300 and now own a 450.  The 300 was not lacking in power comparatively whatsoever.  Especially with a pipe, silencer and good gas.

we re lucky if KTM does exist for another 1-2 seasons.

with the 300 EXC as the only 2 stroke in their 2027 enduro lineup and bold new graphics it doenst look to good at the moment.

They have a Big problem- loads of good enduro and MX bikes from different companys are on the market (Kove, Triumph, Ducati all have good 4 stroke bikes, new KX 2stroke, Suzuki recently won the SX Title...)

i think Bajaj will double check their sales before developing a niche Bike wich has already competitors having good products

They are selling the 300, 250, and 150 xcw in the 2027 US line up.

His Dad ( one of the Original Stars of Hard Enduro) did to, with an EFI'd 250  or 360 Husky, around 10+ years ago. It was used only a few times, and, Husky did not 'highlight' it in any way - just a few canny photographers cottoned onto it. 

I've been trying to find the pictures of it in my folders - they were 'in action' ones taken during a Hard Enduro or two. 

I believe that the tech was acquired when KTM bought the Italian Husky set up. It was a Throttle Body Injection set up, from my dim recollection.  

Enduro21's article about the 350 perhaps coming :
