FE/FC 350 gearing

What have you tried and liked?

i'm still on 14 front, stock rear. Will be keen to try the 13 front once i'm back riding and maybe a 52 rear if it's not the stock rear already (can't remember what stock is off top of my head)

13/52 is stock, I've been running 13/53 and like it MUCH better than stock.

I was actually thinking of trying to go the other way 13/50 ? More like the stock gearing on a KTM XC. I have been riding a 14 250 xcfw quite a bit and it also has low gearing, and I end up shifting more instead of stretching the gear In The revs.

Just my thought tho... was thinking this because the xc-f 350 I have riden felt really good and since the internal gear ratios are very similar with the FE difference just being a lower first and slightly taller second it might make first more usable for me.

Top FE 350, vs. 350 xcf.
Bottom 350 xcfw vs. 350 sx

A friend of mine is running 13/48 and loves it. He can use 3 gear on almost all the mx track and with the high rpms available on the 350 it works out great for him.

I have the 2015 KTM 350 XCF and the stock gearing 13:50 feels pretty good. 1st is a little low but useful and the rest seem spot on. I thought the FE and XC were the same but now see the FE and XCW are at least gearing wise. I'm new to KTM and the new Huskys.

Part of the reason for the 13/53 is because I'm 225lbs lol and the other part is because I only do woods riding and don't like using 1st (or shifting through neutral). I've hit neutral on tricky sections and it no fun! It does cost you on top without a doubt. If the FE's had the HP of the 350 MX bikes it could probably pull the stock gearing with me on it.

chums ,

Good point I to am carrying around a little extra holiday weight... Christmas 98 was a good year ☺️

I live in central Oregon and that where I do must my riding these days, so either fast desert trails or 2nd, 3rd gear single track. But I do get in some good tight single track and hitting neutral does suck
It's funny how everyone has that "sweet spot" they like to run in the gearing (2nd for me) with the right RPM

With the research I have done (could be wrong) is that the FE TOP END is the same as a XC KTM with comp ratios etc... Yet lower end is more off-road woods xcw, but they put it all in the SX frame! Husky just picked and choosed the best parts to use

I run 13/50 (Stock) on my FC350 and I want to try 13/52 as first gear is too high for trail riding... plus I have a Rekluse coming to help with the stalling..

I might build a gearing calculator for the husky when I get a spare 5 mins

I have a ktm 350sxf which should have similar gearing to the xcf, and I run 13/50 gearing at the moment but will be switching to 13/49 gearing once the rear sprocket wears out (which shouldn't be to long).

so I have built a gearing calculator which shows max gear speeds, RPM at various speeds and shows what changes sprocket changes make compared to standard.
Before I upload it and tidy it up, does anyone know the max RPM these bikes do?

I believe the 350 is 13,500

Here is a link to it https://docs.google.com/spreadsheets/d/17RdvvNc1lcfrVWttmGxIiL5O-g8gaR_lv0bDu5YTAoU/edit?usp=sharing

I built it in metric then converted the metric to imperial via excel function, from what I could see the calculations are correct.
nothing is locked so you can edit it to suit other bikes

can someone try to edit and save the changes in a cell, happy for the gear specs, min/max rpm and tyre size to be changed but not the calculations

Oops my bad think the FE IS 12,000 having hard time finding the other models RPM

did you try the calculator?

Tried to change the rear sprocket to a 50, but won't let me???

try now

All good now, thanks champ!!

Try this using the KTM version of the bike
