Which 350SXF upgrades would you go with, and why?

I’m hoping to find people with real world experiences, not just uneducated replies. And yes, I know the bike is plenty capable as-is out of the box and no matter what I do to the bike, I’ll still be old, slow, and fat.

Triple clamps. Which brand would you go with? Should I go with X-Trig or Neken SFS? I can’t stand the stock black clamps, so I’m replacing them with an orange set.

Exhaust. It’s hard to find many reviews on exhausts nowadays it seems, or maybe it’s because this bike is the weird one that isn’t popular with aftermarket reviews. I did read the PC exhaust didn’t do much other than change the sound and lighten your wallet. I think I read the Rocket exhaust, with mapping changes (and maybe fuel?), was good. I’ve got a friend that says the FMF system woke his bike up, so I’m putting that into thought. Does anyone have experience with the Akrapovic Evo system? Any other exhausts recommended?

Ignition. I’ve been waiting for the Keefer comparison between the GET and Vortex I swear I heard him talk about to pop up. Anyone on here have experience with either, or both? I’m not super serious about getting an ignition unless I’m talked into it, but I’d like to hear thoughts on them.

Wheels. I’d like to keep the cost of a decent wheelset to under a grand. I read the thread about the Tusk wheels, and despite them being very budget-friendly, they had a lot of good things said about them. How about FasterUSA? What about the ones in the KTM Powerparts catalog?

The bike is a 2018 model.

Look at your wheels and hubs. Don’t need aftermarket.....

One of the best upgrades performance wise to my 19 350 is mapping and Vortex from Twisted Development.

Clamps, personally I like X Trig ROCS.

Exhaust, I’m a fan of Yoshimura.

Wheels, I like DUbya ultralights.

Last upgrade for performance is suspension, IMO.

Id do forks before anything else honestly. Find a set of ohlins or kybs

Definitely suspension first. Either revalve or a better forks and shock, depending on how much you can spend. You can go faster, safer and for longer. Power is nothing without control.

CV and Trax are already on the way. It’s everything else I’m curious about.

I did 51 rear sprocket, yosh titanium full system, Tokyo mods ecu re-flash, vp u 4.4
Titanium propegs, kyb suspension front and rear, xtrig clamps, Honda steering damper coming soon. I can holeshot the 450’s on this thing and I’m not sure exactly which has more benefit power wise but the combo is by far better then my buddy’s stocker. Next on the list is a vortex because I spoke with an engine builder who’s said the 350 kicks ass with the proper tune and doesn’t need cams or high Comp piston to wake it up ??‍♂️ He knows his stuff so I’ll give it a shot. If you find any Black Friday deals on a vortex let me know and I’ll do the same!

This is a no brainer:

1) Xtrig all the way

2) FMF all the way

3) Both Vortex and Get are good choices but i would go with Vortex

4) Go with SM PRO WHEEL (One of the lightest wheels out there = unsprung weight bro)

But before all that, yes suspension comes first (CV or spring inserts)

Can I ask why you say Xtrig and FMF all the way? Do you have experience with the full Yosh and Akra systems on these bikes?

Thanks.

I agree with all this. The Neken SFS is worth it if your forks are absolutely terrible.

Rocket exhausts look great on KTM’s because they are smaller in diameter than most....but, I have no idea how they perform.

Congrats on the CV forks already on the way, my jealousy meter is pegged.

This is what I have done to my 19 350SXF.
FMF Silencer
Ohlins Shock
Ohlins inserts ( still had forks with these in so, swapped forks )
2 stroke filter cage
Opened up filter cover
Raptor pegs (off my 16)
Vortex ECU from TOKYO Mods
51 t rear sprocket.
Various bling off my 16

On my 16 350 I had Akropovic silencer, I swapped it out for a full FMF system, and standard ECU remapped my TOKYO Mods, the difference was amazing.

I’ve got a EXP Core 3.0 for it. I’ll be buying the CX upgrade kit for that. I agree though, it’s the best things I’ve ever bought for a bike!

What I've done to mine:

KYB (A-kit) conversion, front and rear
PC linkage
51 tooth rear sprocket
Removed filter screen
Tokyo Mods re-map
Full Yoshi exhaust

The suspension/linkage was far-and-away the best money I've ever spent, and it's what I recommend all 350 owners do (the stock stuff is awful, IMO)...I see you went with CV and Trax, so you're all set there.

Then the whole +1 sprocket/screen removal/remap/exhaust made for a very nice little package that really opened up the motor...gave it a lot more snap down low, while still letting it scream up top. I say unless your a A-class rider, I wouldn't spend the extra money on a GET or Vortex ignition. I was ready and waiting to get headwork/cams done, but after all of that, I honestly don't see the need.

Same goes for wheels...I don't see the need to upgrade, unless you just want some bling and the money.

Tell me more about the linkage?

I’ve got the larger rear sprocket and the two stroke cages. I’m definitely not an A rider, so I’ll take the Vortex comment serious. Like I said, it’s not a priority by any means. As for the wheels, pretty much for the bling factor. If I can’t go fast, the bike may as well look the part.

KTM worked some trickery into the stock linkage in order to run low springs rates - thus save weight- but it created a very dead and harsh feel. The PC linkage fixes this," allowing you to run a true-to-weight spring and giving it a linear feel.

With the stock linkage I found that the rear end would not settle into corners/under breaking, squatted far too much under acceleration, and was harsh through chop. With the PC linkage (and a revalve) all of this was greatly improved, especially turn in feel.

I did the entire linkage...bell crank and arm.

You do need to go up 2-3 spring rates. I went up 3, from a 4.2 to a 4.8

How much? I have a 17 Husky 350 and am thinking about getting one.

I have a 19 KTM 350. I just put an Akrapovic full system on it this week and will test it tomorrow. I took the baffle out of the exhaust. I changed the bars and put a spring conversion kit from Enzo in. The spring kit is way better than stock but not on par with my Enzo Suspension I had on my YZ450. I am going to put Kit Suspension and new wheels on it next. I also run a 51 tooth on the rear and really like it.

The PC link lowers the wheel rate for the initial 70% or so of wheel travel (requiring a stiffer spring and valving) and then ramps up significantly at the end of travel for increased bottoming resistance. It's definitely an upgrade over stock when paired with proper springs and valving. We designed our first linkage with similar geometry to the PC, but have since designed a new version that has slightly better performance and fixes the issue with spring interference at the swingarm that the PC link has (only an issue on high spring rates). You can see the wheel rate curves on our website (very bottom of the page). The PC curve is similar, but a bit more progressive at the end of stroke. We found it to pack up a bit in some situations.

Billy - is the linkage knuckle you offer all that is needed to address this issue? I realize valving and springs will need to be changed.

Yes, you only need the knuckle as this uses the stock link arm length.

How much did the Enzo spring conversion run you?

It was around $1000 I think for the springs and revalve.

11/23/2018 2:26 PM

125 filter cage and the quick throttle cam first. The stock pipe is good, if you map it correctly. For the money and logistics to you, getting the ecu mapped at TZR is your best option. If you want an exhaust though, they are all good if mapped correctly, but performance wise you can really do good with the stock system. Also, the stock clamps are neken so you'd be paying that money for the color and the bar clamps basically.

For the cone valve forks, is this the set up (conversion) or something else?
