Tomorrow, we will see the next iteration of the Harley-Davidson Sportster – a move tipped by the Bar & Shield brand’s not to subtle “From Evolution to Revolution” premiere tagline.

That tagline is a nod to the names of the Evolution motor that powered the previous Sportster generation, as well as Revolution being the name of Harley-Davidson’s new motor platform, which also powers the Pan America 1250 adventure bike.

The new Sportster is tipped to look a lot like the Harley-Davidson 1250 Custom that Milwaukee has been teasing, and now the latest reports are saying that the new Sportster will have a potent 120hp on tap.
