Sometimes companies drop concept vehicles with tons of details and no hope of ever getting made. Sometimes, you get virtually no details but assurances a real-world version is coming. The BMW HP4 Race Motorcycle is among the latter. BMW Motorrad's president has promised that the production model will have the same full carbon fiber main frame and carbon fiber rims shown in the preview, but that's about it. Otherwise, you'll have to wait until next spring for more information, like when you can place your order for a highly-limited, hand-manufactured example of your own.
