What's one example of a successful collaboration between a motorcycle brand and another company or organization? What made it work well?

A great example of a current brand that has links is KTM and CF Moto there sharing the basis of engines that has given people reassurance when looking at a new brand like CF Moto. Unfortunately at the peril a lot of people are looking down on the new chineses brands however with this link and great build quality it's really turning things around and a great alternative.
