I've never ridden a Rocket Three but I'm sure they are a formidable power cruiser. I have owned two other modern Triumphs though and I certainly don't miss the service costs. Surprisingly, boxer BMW's are cheaper to keep on the road, particularly if your into big kilometres. You won't be disappointed with the new GS once you get acquainted. It's an amazing bike that just does it all so easy. Simply trust the Telelever and ride it like you stole it.
