Here’s what you need. I’ve done this mod to both of my 2019 MXR’s and it’s awesome. Makes riding the bikes even more fun and believe it or not, it doesn’t mess you up if you jump back on a normal gas bike with a clutch and rear foot brake.
Note: I just ordered the last 2 from KTM Parts (according to them). & their next shipment will only come in in Jan 2021. At least that is what they told me. They do seem to have the best prices on that part.
if not availlable any more, i took the Magura clutch cylinder from KTM (Magura 167 with 9,5mm diameter) and ordered a brakeline from a brake manufacturer
