The stator assembly is or was only sold as a set with the stator coils, ignition trigger, complete ignition/stator wiring harness with the connector plug and the stator's flywheel included at purchase.
They have never been offered separately new from either BMW or Husqvarna. The CCM GS450 enduro bikes also used the BMW G450 engines and later on used the 6 spd. Husky engines in their production depending on the timeline.
You need to be aware that some late production flywheel's will not work on the G450Xs crankshaft unless the G450X that you own may have had the crankshaft possibly replaced in the past during a rebuild or engine failure.
Later Husky crankshafts from late 2012- 2013 Husqvarna 449/511 may be the same, until you go to fit the flywheel on the end of the crankshafts stem and find out the flywheel won't go on the later model cranks wider woodruff key or vice versa, meaning the flywheels woodruff key slot is too wide for the narrow woodruff key which will alter timing and be a sloppy fit..
If only heard of 1 of the narrow keyways that has ever sheared in one of these engines but later years of Husky production from like 2012-2013 the crankshaft and flywheel were both slotted for a wider woodruff key to resist shearing.
So the G450X, Husky 449/511 and the CCM 450s stator itself will work on all of these engines but the flywheel has to match the woodruff key and there are 2 different widths.

No, it won't fit.
However, the Stator in the 2011-2013 Husky 449/511 is the same.
The only possible difference is the flywheel itself, if buying a new stator/flywheel assembly.
Some of the later version 449/511 crankshafts had an upgraded, wider woodroof key to locate the flywheel on the crankshaft and of course both the flywheel and the crankshaft has to have the matching slots for the wider woodroof key, that have been machined to match in both the flywheel itself and the crankshafts snout.
These later version flywheels that come with a new stator as an assembly, will not fit on the early style BMW G450X factory narrow slot crankshafts.
Unless the crank in your bike has been replaced at some time with a newer version itself.
As for the stator coils, hall effect trigger, wire harness, etc. they are all the same for the G450X and the Husky 449/511 I should also mention the same in the CCM GP450 as well, so as long as your flywheel isn't damaged and can be used, you can look for the stator from a 449 Husky.

If you find an alternative bike that has a similar sized flywheel that can be used to replace the stator coils please let us know.

Otherwise keep your head up, they come up from time to time on the 2 Fakebook pages "BMW g450x" and "BMW G450X" as well as the Husqvarna 449/511 owners page. You can also continue to look on eBay as well.

Unfortunately nowadays that's 1 of the main reasons these bikes get parted out in the first place as many owners aren't willing to try to find used parts to use as a replacement.
