2022 KTM 150SX Two Stroke TESTED - Motocross Action Magazine

#motocross #action #twostroke #motorcycle
Motocross Action tests the 2022 KTM 150SX Two Stroke in Southern California. The 2022 model returns with a lot of the changes you are familiar with from 2021. The new items on the list are new graphics, new blue seat cover, and orange frame like the factory editions. The KTM air forks work great on the track if you spend the time to adjust them to your ability and weight. The engine is fast, playful, and very competitive. Check out what the Motocross Action wrecking crew had to say about their first day on the new bike. We compare it to some of the 125 offerings from the KTM group as well to give you a better idea of which bike might be a better choice.

On my 2021 tc 125 their is a little red ring that might look like a dust gaurd at the bottom of you fork legs but it is not a dust guard.

I have a 2012 150xc that I put a fmf pipe and silencer on and it made a world of difference. It came on pipe earlier and pulled longer. I got a fmf for my 2019 150sx and was very disappointed with the power "gain" the only difference I felt was it was a little snappier than stock. It didn't come on pipe any sooner or pull any longer. I'd spend the 350 bucks elsewhere if I could go back and do it again

I'm trying to get off my 450 and onto a 125/150. I thought at 6'0" 180lb that the 450 is what I needed but learned the hard way that it's just too much power.

Power/Torque output stock? Also what would be the additional cost to squeeze some extra hp out of this bike?

I mention it at 3:32, stock KTM 150SX has 40.7 horsepower. It also has 18.83 torque stock as well. Pro Circuit built a mod 150SX for us last year that produced 43 horses and 19.77 torque. It cost $349.95 without counting installation and the Pro Circuit pipe/silencer we used.

Maybe in SD

[@northwestrider369]

When you say the 125 is more torque out the corner and later say that an aftermarket pipe helps a lot. It sounds like KTM just used the 125 pipe and it isn’t really matched for the extra 50cc. Even though it’s only 25cc more, I would think it had torque lower in the rpm at least more at the same rpm. So yeah, it sounds like this pipe is not tuned for the extra cc.

so I’m looking at buying one, but I’m 6 foot 2 and 100kg in weight. I’ve owned plenty of 125s and 250fs my last bike was a 250 2 stroke and although I ride pretty good I have a lot more fun on slower bikes for some reason.. will this bike be alright for me to ride most weekends being my height and weight?

[@MS215_]

Im in the same boat!

[@motominded5275]

the 125s are same size as bigger bikes, several pros over 6 feet. Weight is bigger issue but it has plenty of power to pull you around...

[@liameklom]

@@motominded5275 yeah I’m aware of that, I’m just worried if I get a 150 that I’d be having to do top end rebuilds more then normal because of my weight and the stress under load for the motor

[@WilliamStewart1]

I find a well setup 250 2t is the way to go. My YZ is setup for all bottom and mid and it's a blast to ride now, don't have to fight for power and makes the riding experience overall a lot easier.

[@ConnorsCorner1]

Late reply, but Im 5'10" and weigh 195lbs. My 125XC has more than enough power to haul me around, extremely fun. I DID have to buy a stiffer rear spring, the stock was just too soft for me to set sag. Running 160psi in the fork, and its PERFECT. I intentionally didnt get a 250sx because I wanted something I could ride the balls out of.

[@daneg]

shame about pipe availability atm. swapping pipes on those 90s 2-strokes was a quick and easy way for amateurs to change the power band without shelling $$$ for more intensive alterations.

[@christophervillarreal8565]

It also doesn't help that they used the 125 gearing on the 150 when obviously you'd want to change that right off the bat and the bike would ride way different then the initial reviews when compared back to back

Man for about a decade I've been wondering this. They always say the 150 is better for vets because it has more bottom end but then they say the 125 is easier to ride.

[@MX-CO]

@@Dylans503 I've heard it said both ways as well

[@mrrrrr1rob590]

As a slower vet rider with a 150 and ridden the 125, the power difference feels even bigger than the 3hp suggests. I find the 150 easier because the extra torque means I don't have to abuse the clutch as much to keep the revs up and because I am not as fast, I am more prone to being a gear too high and lugging the bike more than average.

With some porting and pipe, ...above 45HP, there is no 125 today that comes close. A stock 2021 KTM 125 makes 37HP also.. So where is the advancement? The point being, not to race an older bike, (unless it is well restored), but to expose, the scam they are running, as they have made ZERO advancement in the last 30 years. The only difference is the suspension.... but by the 1990's suspension has not changed at all...despite what the "marketers" sell. In fact a 1989 Cagiva wmx125, already had the "so-called" 'upside-down" forks. Too bad Cagiva isn't making MX bikes anymore.
