2019 KTM 150SX Build

Since the last post I got my orange fork and shock decals in, and got an orange Renthal pad to match my bike better. Got a good deal on some OEM handguards on MX Locker so I put those on, not sure if I want to keep them on yet.

Probably not a whole lot more too soon here but hopefully a full PC or DEP pipe around winter, kinda leaning towards a DEP now.

I love my 150 for sure, but I agree on the gearing. It's got a 12/49 from the previous owner and it's too short, but can't decide if I want to try 13/49 or 14/50 quite yet. Couldn't tell you the exact spec on how far the head was taken down, but porting wasn't too extensive as these are already pretty close from the factory. Mainly just cleaning them up a bit. I have to run it on straight 110 due to the higher compression, which I use VP C12 for. I also have the red PV spring. Riding it compared to my buddy's stock 150 it definitely feels like it pulls harder, especially higher in the powerband.

Threw a couple different things on since then but nothing major, new set of MX34 tires, clear stompgrip, pink grips, etc.

Over the past few nights I decided to strip the whole bike down to the frame for powdercoat, I have a cool idea planned which I wont share with anybody until it’s done! Will also be adding extra cool bits as I can afford but I’m hoping to get the bike assembled ASAP for indoor moto season.

Been a few weeks since I’ve updated, since then my frame came back from powdercoat & I begun reassembly. Still waiting for my head, water pump, and PV covers to return in the mail as well as my swingarm bearings to arrive. After that it should be time to fully assemble.

Been a minute since I’ve updated here. As of right now, the only thing I’m waiting on to put the bike completely together is Pivot Works to warranty my swingarm bearings. 1 of the 4 sent was bad, so the spacers won’t slide into it. Motor parts arrived, got a full PC exhaust, and maybe a few other bits & pieces since last post. Going to buy a JD jetting kit & replace the faulty jet block gasket to get it fully dialed.

Starting to drift away from that haha. Still cheaper than my RM125 build 😆

Finally got the swingarm bearings pressed in. Now I'm just waiting on my chain, chain guide, and a few miscellaneous bolts to arrive to "complete" the bike for now. Thinking about playing around with different bar bends, I like these tall Renthals but I'm sure it hurts my form and makes me stand up too straight. Also might ditch the hand guards, opinions?

Any idea what a similar bend would be in Renthals? haven't looked yet but I was thinking about switching to twin walls.

Ditched the handguards, and finally got my chain in to give it the first ride. Might remove the orange skid plate and eventually replace it with a carbon one, I feel the orange is a bit much down there. I also installed an orange Acerbis chain guide kit but I think I'll eventually swap it for a black one, again I feel it's a bit too much orange. Jetted it with the JD jetting kit and replaced the jet block gasket (mine was toast at 36 hours) and it couldn't be running better.

Got it put together and “finished,” the only things to do are replace the orange skid plate with a carbon piece, reprint the old swingarm decals as they don’t fully stick, and I am getting new bars very soon. After riding a YZ with 827 bend FatBars I’ll be going with that bend in twinwalls. Should be selling my old KX100 within a few months, so I can focus on my RM125 that’s been on the back burner for 2 years.

Won Dunlop’s weekly tire sticker giveaway a bit ago, gives it a nice little touch in my opinion

Took it for the first official rip at a track on Sunday, only complaints are my bars which I’m replacing, and then my rear spring is too stiff which I will replace when I find someone letting go of an OEM rate spring. Previous owner was much larger than me so I can’t even loosen the ring enough to get sag right.
