The new harley-Davidson XR1200 seems to be racking up the kudos. Motorcycle Daily has a write up on it, and they conclude:
This is the ultimate Harley-Davidson Sportster, with performance and reliability completely unknown to the guys who owned a Sportster decades ago. Guys that dreamed (like Erik Buell) about what a Sportster might be or might become. That dream is finally a reality, with factory reliability and a factory warranty.
From what everyone is saying, this seems like the closest thing to a modern sportbike that Harley has ever built.
