Description - This is a good used transmission with 93 hours from a 2017 KTM 250 EXCF.  This will fit 2017-2019 KTM 250 EXC-F and Husqvarna FE250.   But,  as an assembly this can be used in many other KTM's.   This cannot be mixed and matched with other transmissions though, the splines are the shafts are different,  so you have to use the included gear ratios. As an assembly this should fit 2016-2022 KTM and Husky 250F/350F.  This also fits KTM and Husky 2-stroke 250/300.  This has a 13th tooth 1st gear (on the mainshaft),  Other bikes have 14 tooth and some have 15 tooth.  It'll be a big change,  making a pretty low 1st gear.  If you have anything other than a 250 in FE or EXC-F,  I would suggest comparing the gear ratios so you understand what to expect with the change.  Please message me if you're not sure about fit,  if you contact me, I can guarantee fit.  I have listed the correct part numbers. Here are the gear ratios.
