2023 KTM 300SX Two-Stroke TESTED

#motocross #sports #outdoors #adventure
Motocross Action Magazine tests the 2023 KTM 300SX Two Stroke at Glen Helen Raceway. What did we really think of the bike? The $9199 KTM 300SX lives up to the hype. It is ultra-fast, ultra-smooth and ultra-stable. Because the bike is so fast and so comfortable out of the box, we think many riders will be happy with the stock setup and won’t feel the need to add on oodles of aftermarket upgrades.

God bless KTM for continuing to develop 2 strokes.

This bike should be allowed to race by the AMA. The 450 class needs something different and I think bringing the 300sx into the mix will create more diversity rather than an unfair advantage.

The AMA should allow 300 two strokes to race against 450s. That's a fair equivalence, especially considering you dynoed the KTM at 55 hp, which is in the stock 450 ballpark. Back in the day, they put two strokes at too much of a disadvantage when they limited them to 250cc's.

I love my 300SX!!!
It’s the best 2-stroke I’ve ridden!!
The power and handling are top quality!
Excellent job Josh!
Looking forward to a modified test of this model in the future 👍👍👍

I haven't ridden mx since 2015 - the part I miss the most is finding a natural jump on some terrain and just hitting it all day until you have it so perfect it's just like butter

[derkbrock]

Would love to see a carson brown type on one of these especially with how the field is looking rn in the 450 class I bet he could top 10

I think the aftermarket pipes will open up the rev a bit more aswell. Admitting it is great to see KTM pushing the r&d, but a slight concern if they want to mimmick the four stroke powerband, i think two stroke should keep the classical bark, but that is my subjective opinion.

[gamermoejoe]

Love my new 250sx! A PC pipe and silencer is a big improvement over the FMF equipment though IMO

[davidmcnerney]

The AMA Needs to let the 300 compete in 450. Every 450 moto this year has been boring other than hearing Matt Burkeen ripping around.

A stock 300cc peaking at 55hp, truly amazing. Wonder what an ECU tweak can do. Probably fatten the powerband and grab a couple of horsies at peak.

When has Yamaha ever used an electronic power valve on a 2t? I think you're thinking of sherco.

[derkbrock]

300 should be aloud it 450 class and 250 in the 250 class for the pro nationals it’s a no brainer

[koybaker]

I just got my 24 300 SX can't wait to rip it this weekend! 🤘

[HPRaceDevelopment]

no - yamaha has not use an electronic powervalve, ever
TM has and Honda has

the yamaha uses an electronic powerjet

I had one for 4 hours. Sold it because of bad knee... Bike felt really rigid in frame and suspension at first. A little better already after 4 hours. I was happy with the ergonomics of the 300 SX. Engine character didn't make me all smiles. The rev limiter is a problem IMO. My old Husky TC 300 -18, with Keihin carb and lots of mods (RK Tek head, FMF pipe et c), pulls stronger everywhere in the powerband and revs far longer. A few tweaks with the ECU and some more time to soften it up I think the 300SX will be a winner though.

I must’ve got a knockoff yz250, bc mine doesn’t have a electric power valve 😢

[Krondelo]

I was privy to ride this bike. Not track tested but damn I loved it!! 9/10.

[spacejaime]

Josh - I've never seen you this fast at Glenn Helen (on video, of course). You are truly hauling butt!

[HotBlooded_]

Marked! Best regard from the Philippines! 2stroke user. I can smell the smoke 💨💨💨🤘🤘🤘

[kelliebrooks]

Great video its always nice to watch someone shred a new mx bike on a sunny day...especially one that sound propper
