BMW S1000RR HP4, almost one hp per kg

BMW delivers a new blow to its S1000RR. After releasing the 2012 version earlier this year, it now takes one step further and surprises us with this new version, the HP4. For those who don’t know what the HP designation means, here is a brief description: these are the most extreme versions of their models.

The HP4 is the motorcycle taken to its extreme, a bike that will be available for the street for around 20,000 euros, each one unique due to the engraving of its serial number. And we say taken to the extreme because its power-to-weight ratio is almost one to one, without a doubt, thrilling.

It is a motorcycle you could jump straight into a Superstock championship with, although its modifications are almost closer to the Superbikes themselves of the world championship. The new BMW incorporates the DDC (Dynamic Damping Control), the famous system through which BMW ensures we get the maximum power at all times, whatever the conditions, reacting to bumps, acceleration, braking and corners.

Looking at its numbers, we are dealing with a motorcycle that produces 193 hp (142 kW) at 13,000 rpm, with a maximum torque of 112 Nm at 9,750 rpm. But the motorcycle has not only been tuned for more horsepower; it has also gone through the “bikini operation”, reducing its weight by a total of 8.8 kg, bringing it to 199.2 kg ready to ride. This weight loss is achieved through a change in the exhaust, incorporating a titanium Akrapovič, along with other tweaks such as forged wheels and an even lighter battery. The traction control has been revised, which had always been one of its weak points, and it also incorporates a quick-shifter, so shifting from one gear to the next will be instantaneous. In addition, it features the rear tyre in the 200/55 R17 size for the first time.

But when something improves so much in power, its braking performance must also be reviewed, and this is another of its strong points: a new Brembo braking system, with floating discs and monobloc pads, combined with a race-grade ABS with four possible settings: Slick, Race, Sport and Rain.

And in case that were not enough of a racing motorcycle, it tops things off with a launch system (Launch Control), in which an anti-wheelie system kicks in, keeping traction always directed forward and minimising power losses in anything other than pure acceleration.

Aesthetically, we can see its black fairing and the characteristic single-seat tail, although a kit is available that adds a seat and footpegs for a passenger. Apart from this kit, there is another one that makes the bike even more racing-oriented, incorporating several parts in carbon fibre as well as adjustable footpegs, levers and wheels with a blue finish. Blue and white appear everywhere, even on the instrumentation.

A true racing motorcycle within reach of the most dedicated enthusiasts of the Bavarian brand, who will still have to wait until September to see it live and in person.
