10mm spool kit with special bolts for use with KTM's
thread pitch which is different than other modern sport
bikes that use 10mm spools. Some Husqvarnas also use this thread pitch now due to their affiliation with KTM. We are not certain which Husky models use these or for what year models, but we will post what information we have in the fitting notes.
Early RC390 models use traditional 10mm spool kit with 1.25 thread pitch. We are not sure when they changed over to 1.5 thread pitch but it was before 2020.
This spool kit is only available in our Delrin material
due to the custom bolt only being available in the
appropriate length for that kit.
