2023 KTM 300SX Baseline Settings – PulpMX

Since I swung my leg over the 2023 KTM 300SX I’ve been consuming my phrases on how a lot I dislike two strokes. That is the primary two-stroke that I’d even take into account on buying and to me has a mix of 4 and two stroke efficiency. I’ve been purposely sitting on this text for some time to see if anything has popped up with this machine, however the time is now to launch a few of these “simple” settings that you are able to do to your orange two stroke machine with a view to make it much more enjoyable to journey. We’re presently engaged on unlocking the closed ECU field with Twisted Improvement so search for that article/video as quickly as we bought one thing good for you guys to attempt. Listed below are some issues that I’ve tried and settings which have labored.


The KTM 300SX suspension isn’t as inflexible feeling because the 4 strokes however the bump sticks on this machine can get delicate if you happen to’re north of 185 kilos. Here’s a setting that match riders from 170-190 kilos.


Air: 10.7

Comp: 14 out

Rebound: 14 out

Fork Top: 4-5mm


Spring Charge .45N/m if beneath 185/ Over 185 kilos transfer to .48N/m and again off compression

Sag: 103mm

LSC: 10-11 out (.48N/m spring run 15 out

HSC: 1.25 out (.48 N/m spring run 1.5 out

Rebound: 11-12 out (.48 N/m spring run 12 out)

Pipe/Silencer: I’ve tried a pair units of pipes/silencers and surprisingly the Payments pipe and silencer had he cleanest burn in addition to had probably the most torque really feel within the mid vary. The FMF was good for throttle response however felt a bit of flatter on high than the Payments. I had one among my buddy’s reference me to the Payments and lately had a fast spin on one other bike with the Payments and was pleasantly shocked. Though no pics have been taken the Payments pipe is a uncooked wanting pipe with across the identical mount of low finish really feel because the inventory system however with extra mid vary torque with a stronger pulling high finish/over-rev. I used to be throughly impressed and large thanks goes out to my man Ernie for pointing me in that route. The FMF Fatty and a couple of.1 silencer was good off low finish however wasn’t as robust close to the highest finish/over-rev because the Payments. The price of the FMF can be a bit of on the steep aspect relating to a 450.00 silencer! WHAT! Sorry, however there may be NO method I’m spending 450.00 on a silencer. The Payments appears to be the higher purchase right now. I’ve but to attempt a Professional Circuit system, however plan to quickly so search for a separate take a look at on my web site quickly.

Wealthy Feeling: KTM recommends a 60:1 combine ratio however for me I’ve been operating a 40:1 commonplace combination with the T2 gas that I’ve been utilizing and it feels much less wealthy feeling on the observe. With the VP T2 race gas the KTM 300 SX feels extra responsive and fewer “loaded” up after I stab the throttle earlier than I land from a leap. This provides me a bit of extra of a light-weight really feel in corners because the throttle response is crisper and has extra low finish RPM response. In case you have some cash to “burn”, attempt a 5 gallon pale of T2 and see the way it goes. It has been working nice for me since I can’t get into the ECU field but.

Vented Airbox Cowl Or Non Vented:

I’ve went backwards and forwards on these and to me, the KTM 300SX runs higher with the closed off airbox aspect cowl. The open cowl made the wealthy feeling worse when landings off jumps. Leaving the closed off airbox cowl on helped throttle response and clear really feel on the observe.


Rattling you Jody! I went up a tooth and now am on 13/50T to assist with third gear roll on. In the event you like second gear cornering then follow the 13/49 gearing however for me the 13/50T gearing didn’t have an effect on the second gear roll on as a lot as I’d have thought. The 13/50 gearing additionally helped with low finish restoration, particularly when the observe is loamy/sandy.

Different Small Mods That Assist:

Professional Taper Evo Bars: Helps with vibration and slap down landings/bump impacts. I’m presently on Race Group Evo bend lower to 804mm. Inventory size is 810mm.

KTM Manufacturing unit Version Clamps: Break up clamps helps with entrance finish really feel and traction when on the sides of your tire.

ZRT Throttle: The ZRT throttle tube helps with twist really feel and stays gentle feeling at some point of your bike’s life. Even when the the throttle cables get worn after 25 hours, the ZRT throttle nonetheless stays gentle feeling which is a large plus for feeling involved together with your bike when using. A lightweight feeling throttle helps with kind in addition to elbow posture. I’m not making an attempt to get all RYNO on you however a tough pull on a throttle places your proper arm in bizarre positions popping out of corners because it forces your wrist and elbow in a hen wing place.

Dunlop MX3S Entrance Tire: You already knew this proper? Placing a MX3S on as an alternative of a MX33 will assist your lean angle traction and entrance tire contact patch really feel. You’re welcome!
