TE/TC Te300 starters

Any smart guys on hear that have cheap alternatives for rebuilding/replacing starters? One day i will need one or have to rebuild and i love to have knowledge. Plus my brother will have xcw 300 soon as well. I dont use my starter much, never maint serviced yet as well, still new bike. Read on wet mods and maint and replacing now instead of last minute. Thanks for help guys!!

I have a '12 Husaberg TE250 and the starter motor gave out after 3 years. I just replace it with the upgraded OEM 410w starter used on the newer bikes and it was worth the money. I have friends who have rebuilt their starters multiple times, on older KTM's and the rebuilds don't seem to last. There is a cheap Chinese manufactured 410w starter motor, as another available option.

There's two things that go on them eventually.
1-Normal: the brushes wear out after extended use. If you do a big service or rebuild, I suggest throwing a new set in, as when they are borderline they start to arc and do damage to the armature.
2-Total: The armature has it... mostly a short in the windings due to overheating and bad contacts on the brushes, which also wears the collector out. The armature is the most expensive part in there in most cases so...bin!
In a lot of cases you can't even buy the armature separate. I have to have a look if KTM- Husky supply this.

Bearings? If you ever wear these out in a starter you have done a heap of starts or rode it home on he starter... only happens in trucks and high mileage cars.
