I need to move the shifter tip about 10mm rearward (closer to the foot peg) on my 2023 MC350F without changing the height..
Has anyone found a quality shifter from the aftermarket, or another KTM application that has a 10mm shorter reach?
I've considered machining a new shifter tip for the stock lever, or one of the Tusk levers if I can't find something I like.
Cut and rig weld back?

If hammerhead doesn’t make a KTM one, their tips do fit on the tusk shifter.
Zeta Revolver shifter is adjustable, but I don't know how much shorter it would be turned toward the back.

According to their info, the rear position is "standard" and front is +5mm.
Thanks for these suggestions.
I've considered chopping and welding a shifter, but welding is going to be my last resort.
As @FGR01 pointed out the Zeta has 0mm to +5mm offset.
The Hammerhead website shows that they're offering the same deal; stock or longer.
I looked at some photos of the 85SX shifter. It looks substantially shorter, probably way too short.
The 350F shifter is about 120mm long from the centerline of the splined shaft to the centerline of the shifter tip.
Measurements from middle of the footpeg to the middle of the shifter tip revealed why I occasionally miss shifts on the 350F.
YZ125 165mm
YZ250 165mm
KX500 162mm
KX450 162mm
MC350F 174mm
Maybe I'll order a new shifter and machine a tip for it.
-5mm hammerhead shifter tip was available for my Yz. Used with my new peg mounts that were back 10mm. But maybe not available for Austrian bikes. But I think all tips are the same from them. I have a hammerhead on my 350 I will have to look at. But gets expensive if have to buy their shifter and a spare tip.
Check the length of a 125 lever. I think that they are shorter than the one on the 350.
The 85SX, 125SX, and 150SX seem to share the same part number... It looks a lot shorter.
I've got a buddy with a 150SX, so maybe I can measure it and see if it's a good candidate.
I'm not against buying a 125 shifter and putting on an extended tip if I can get to a length similar to my Japanese machines.
125 shifter will be interesting. I have the 125 and 2020-350 sitting here. The 125 shifter is about 100mm center to center. Potential issue I see, the engine shaft sits further inboard on the 350.. so the 350 shifter has quite a bit more outward length on it.
Can't remember what year it was but KTM made the shifter longer. So maybe the shifter from the year before they did will solve your problem?
That's good info, thanks!
The 20mm shorter lever plus a 10mm extension-tip might be a solution if that lateral offset difference isn't too much.
I'll ask my buddy to try fitting up his 150SX shifter on my 350F to check it out.
@crmx105 , do you have a rough idea which era or year that may have been?
I could search some MXA test articles and compare some part numbers if you can give me an approximate starting point.
Does it happen to be different if you measure/compare the bikes from the front edge of the peg to the center of the shifter? I am thinking the foot pivots off the front of the peg so a wider peg might alter this? Just a theory.
I find the shifter plenty close on my ‘24 350 and I have small feet but not aware of a shorter version. FWIW, the ‘24 is also about 120mm.
Man this is a good catch. I always felt like the shifter was either a half spline too tall or too low compared to all the Japanese bikes I races. The longer length in comparison would contribute to that a little bit. Need a test dummy? 😂
P/N changed 2016. Current P/N is 792234031100. 2015 P/N 54734031000. To be honest didn't think it was that long ago!
In my opinion, you are correct about where your foot pivots and the effect of wider pegs. The reach to the shifter is a lot longer when measured from the front edge, that's what I originally checked with the same thought process of pivoting on that edge to shift. Above I referenced the centerline of the peg to eliminate the peg width as a variable from the conversation...
Front edge of peg to shifter centerline:
YZ125 = 140mm (2010 YZ250F pegs)
YZ250 = 140mm (Aftermarket same width as the YZ-F pegs)
KX500 = 133mm (2010 YZ250F pegs)
KX450 = 133mm (BUD Racing Ti pegs)
MC350F = 150mm (OEM KTM pegs)
I spend most of my time on the YZ250 and YZ125, so they are home base.
Changing from an old set of SG12 boots to some new SG22 boots really exposed this issue last summer.
If the only bike I rode was the KTM, I would just get used to it.
@crmx105 , I'll try to figure out the difference and if the old shifter is compatible... Thanks!
@ithinkitsbroke , if I make something, I can make a few. If I find an off-the-shelf solution, I'll make sure to post it in this thread.
The 250F, 350F and 450F allegedly share the same shifter and they match part numbers that @crmx105 posted.
I looked up some MXA tests and the shifter definitely changed from the 2015 model to the new model in 2016. The photos below are 2015 450 and 2015.5 450 Factory Edition.

If I remember correctly i think it was supposed to be 10mm longer? Again can't believe it was that long ago. Time flies!

Excellent. So, It’s an even greater difference when measured from the front.
Could the adjustable versions, with the standard and +10mm, be modified to add a threaded hole -10mm? Extend the vertical mounting face towards the peg.
Or, use the two existing holes to add a plate with a threaded hole -10mm. That would make it stick out a bit though. Just quick thoughts. Access to a CNC and make one?
I did some swapping around on my bikes... 2020 FC350 and 2021 TC125.. so should be same as what you are working with.
Side by side comparison, 350 shifter on right.
350 shifter and 125 shifter mounted on the 350. I measured 146mm peg edge to shift tip center for the 350 and 128mm when putting the 125 shifter on the 350.
I ran the 125 shifter up and down and checked clearances. It looks as if it could work but it does get very close to the case on upshifts (using the stock spline mounting, roughly level). I could see it rubbing the case at times due to the natural side play in the shaft and pressure from your boot.
Yeah, all that is possible and sensible.
I own a CNC shop and have a side business selling a few suspension components... https://dialedmfg.com
That's great info. I'll keep that in mind as a potential solution.
So you're getting -18 length with the 125cc shifter. If I add a +10 tip to that, I'm at -8mm which would be fine.
In terms of clearance, it's forged aluminum and could be tweaked outward a little with some heat.
Follow that with a water quench, then some artificial aging in the toaster oven and the strength would return.
Here is my 22 350 with a hammerhead shifter, stock length. But other picture is my 05 yz125 with -10 tip, although mounted to a tusk shifter. But the tips are interchangeable as they don’t use a KTM style tip on the hammerhead shifter.
Do you mind measuring the distance from the centerline of the shifter to centerline of peg on those?
Where are the -10mm shifter tips available? Is that a Hammerhead or a Tusk part?
I have a YZ125, so if I need to buy a spare shifter for it to get a -10 tip, I'm not against the idea.
The Hammerhead shifters are now sold through Moose Racing hard parts. https://www.moose-offroad.com/category/17723
But it appears they do not offer the rear offset tips.
I’ll get some measurements when I can, but the -10 tip is a hammerhead part. I bought it through Motosport. It was on clearance, so maybe they were discontinued?
Also, the Hammerhead site is still up and appears to be in business.... you can run down the rabbit hole here. https://hdmoto.com/moto/shift-levers
They offer a "KTM 2-stroke shifter" with various tips. No idea how that shifter might compare to the stock 125 shifter. I can tell you, my 2-stroke 250 has a much longer shifter than the 125... maybe the same or longer than the 350.
I bought my Honda shifter from Hammerhead website a month or two ago. No issues, showed up about a week later. just fyi
According to KTM part numbers, the 19-22 shifters are the same from 250 two stroke up through 450F (motocross models).
The older bikes seemed to have a few different shifters and I didn't look at any of the 2023+ stuff.
If there was just a little more case clearance, I'd buy the 125 shifter with a +10 tip and be done with it.
I think that's my backup plan since I could just bend the shifter out a little if necessary.
I don't see anything shorter than -5mm from Hammerhead, and it seems like they may not offer that anymore as I didn't see any for sale in that offset. This chart seems way off based on my size 10 boot...
Yeah, I mis-spoke second time. I have a -5 because my Yz peg mounts are -10. Here is a link on Motosport where I got a -5 for my Yz…..it’s $17 on clearance. May or may not help.
