will be interesting on the dual injector on a 450, we all know that on the 250s there a game changer, But i recall twisted on a podcast said that 450s dont do great with them. Will be cool to this bike takes it.
I'v been told first week of December 2026, to be expecting delivery in the US at dealers. Although I am waiting to see if the US version will have a slip-on and some different suspension vs what the China release shows. Also no mention of the LITpro connectivity unit which i am a big fan of.
I dont think I will be paying $14,000 otd for graphics and a holeshot device I'll never use. But, we'll know more tomorrow.
New gen FEs usually get a stock muffler so no surprise there. Keefer has been hinting about spring forks going across all models. The dual injector for 250 was already hinted at also. I am surprised the 450 is getting it. The 2028 350 will be a beast with dual injectors.

That shroud makes me think I'm going jousting. FFS.
Other than that, they sound exciting. Dual injectors on a 450?? Metallica anyone? I love the navy and orange look. Hopefully this is what the factory bikes will look like.
Made in china?
Trick. I like it.
“KTM of China”…like KTM of USA. Or KTM of Europe. Meaning the location..
Game changer….lots of early buying Honda bro”s going to be sad….
WP XACT Spring forks
If only there was a 350 FE…
haha, just got off the phone with my dealer. He gave me the low down on this bike. One of the kids they sponser did some R&D for the new model and has a lot of good things to say about it. But, going back to the new Honda thing, I literaly am that guy. New Honda is due in a week or so at my dealer but now IDK. He said the ktm's are looking like early december or even the end of november posibly...Fisrt world problems for sure
I”m just joking….all these bikes are more than enough for 99% of us riders…should probably come down to best dealer, contingency if you race enough….but the KTM sounds solid…
I don't like the new plastic, with the expansion chamber it makes the bike look unnecessarily chunky.
as long as all my ktm stuff transfers over like forks triple clamps and wheels i’ll be good… of course i have to wait for the tree fiddy!
Ha ha this is me too. Been tossing up between this and the new Honda, literally told my dealer yesterday I'll take the Honda then wake up to this. Not sure what to do now 🤦♂️
