Even wet, that gives the HP4 a power-to-weight ratio of just 2.27 lbs/hp. That's nearly twice as potent as a Veyron. In other words, the
Bugatti would need to have nearly 2,000 horsepower (or weigh half as much) to match the relative thrust of the BMW HP4. To get its weight down, BMW Motorrad gave the HP4 lightweight forged wheels, a titanium exhaust and even a lighter battery. Launch control, dynamic dampers, ABS and traction control are all part of the package as well, but don't expect it to come cheap: $25,000, which may seem cheap for that kind of performance in car terms, but that's a hunk of change and a half for a motorbike.
