Nevertheless, my biggest surprise at the launch
of the 2012 S1000RR was the boundless enthusiasm each engineer, no
matter if gray hair or no hair, showed in regard to sportbikes. There’s a
lot more to this performance-driven crew than just building
transportation appliances, as we found out at the Ricardo Tormo circuit
in Valencia, Spain, where the bike’s 2012 edition was sampled by the
world’s media last week.
For example, Ralph Schwickerath, the S1000’s chassis project manager,
is not only a mechanical engineer but a former racer who is nearly as
quick as Jurgen Fuchs, a BMW test rider who has raced in 250cc and 500cc
Grands Prix. And the RR’s dual project managers, Rudi Schneider and
Josef Machler, were both suited up and ripping around the grand prix
circuit in a rare display among OEM senior managers. And then there’s
58-year-old Markus Poschner, BMW’s general manager for the K and S
series platforms, who chooses the hardcore S1000RR among BMW’s selection
of more comfortable models when he takes his wife out for rides in the
Alps.
 The ballyhooed S1000RR gets some engineering love for its 2012 update. It’s literbike rivals should be afraid.

These sportbike enthusiasts are responsible for the overhaul of our 2010 Motorcycle of the Year just two years after first blowing our minds at its first press launch. No other literbike has such an accelerated pace of development.
Sure, this latest version has only seemingly modest refinements, but,
as the aforementioned Poschner told us, “It’s definitely more than just
a facelift.”
The Walk-around
New
winglets (above the RR decal) and tank-top air inlets are part of the
2012 BMW S1000RR revisions, but its most significant updates can’t be
seen by the naked eye.
The RR’s appearance is mostly familiar, with its most notable
revision a tidier tailsection with new ventilation ducts.
Trainspotter-types will notice new aperture grill venting near the top
sides of the fuel tank and the addition of aerodynamic winglets on the
sides of the nose fairing.
Outwardly, our test bikes were outfitted with a new Racing Red and
Alpine White color combo that looks fresh. Also in attendance were a few
RR’s in a new Bluefire color that just needs some Rizla decals to mimic
the Suzuki MotoGP bikes. Returning for another go-‘round is the classy
four-color BMW Motorsports scheme, as well as a Sapphire black metallic
version that substitutes a black-anodized swingarm in place of the raw
aluminum finish on the others.
More Than Skin Deep
Did you notice the 2.5mm shorter offset in the new forged triple clamp?
It’s the changes under the Double-R’s skin where BMW’s engineers
flexed their muscles. Schwickerath told us his goal was to increase
agility while keeping stability and traction on the same levels. So a
similar but new frame was cast, now with larger air intakes and a
slightly higher swingarm pivot location.
The frame change plus a shorter rear shock, less fork offset and fork
tubes held 5mm higher in the triple clamps result in a rake angle
0.1-degree lazier at 24.0 degree and 2.5mm of additional trail to
98.5mm. These minute changes can result in marginally heavier steering,
but this is balanced by a 10mm wheelbase reduction to 56.0 inches and a
slightly higher center of gravity. A slipperier steering head bearing
also reduces effort at the bars.
Suspenders Animation
New stuff in this pic are the revised heel-guard plates and red shock spring. Also note the quickshifter gearbox linkage.
The RR’s 46mm inverted fork and single shock appear outwardly similar
(except for the red shock spring), but internal changes abound. BMW
claims minimized internal friction at both ends for additional
responsiveness.
The fork now features a mid-speed damping valve that builds up
compression damping with greater precision, and the damping adjusters
now operate in a more linear fashion – previously, there was a wide
variance in positions 1 to 5, with smaller increments between 6 and 10.
Meanwhile, the diameter of the shock’s piston rod has been increased
to allow more oil to flow through the low/mid-speed valve, and, combined
with revised needle geometry, results in a linear buildup of damping
force. A new check valve completely separates the influence of rebound
damping on the compression damping.
Let’s Ride!
As it was my first time at the Valencia GP circuit, I agreed to the
recommendation of starting off in the RR’s Rain mode instead of the more
powerful Sport, Race or Slick selections. New for 2012, the Rain
setting now boosts maximum power to 163 crankshaft ponies, a bump of 11
horses, which felt plenty adequate while navigating a new track.
However, the Rain mode also has a more intrusive traction-control
calibration and restricts power while leaned over past 38 degrees, so on
the third lap I switched to Sport.
Now with its massive 180-rear-wheel-horsepower on tap, the S1000
rocketed down Valencia’s front straight. A shorter-turn throttle and
lighter throttle spring gives quicker access to full power, augmented by
using the same throttle curve as Race and Slick modes (previously four
separate curves). The 20% larger air intakes, repositioned exhaust
catalyzers and revised ECU tuning are said to improve power production
between 5000 and 7500 rpm, but all I could discern is this is still the
fastest literbike in any straight line!
 BMW’s S1000RR is still the quickest literbike down a straightaway.

Trackday junkies will still find the electronic settings in Sport
mode not liberal enough. Throttle application is restricted when leaned
over past 45 degrees, which is still well within the adhesion levels of
the Metzeler K3 Racetecs. Sport mode also limits wheelies, which, on a
sportbike this powerful, is a regular occurrence. However, the
wheelie-control system is now less herky-jerky. It has the same
thresholds for the four modes, but revised calibration results in a
slower reapplication of power after ECU brings down the front wheel.
When I wasn’t thinking about electronics, I was enjoying what seemed
to be marginally quicker steering response. Although still not with the
class-leading agility of a CBR1000RR, BMW’s RR is easily coaxed into a
lean and feels composed in corners.
 Getting down on one knee to prey.

Race Face
Next up was the Race setting which has higher limits than most
non-racers – a rider will need more than 48 degrees of lean before
throttle application is affected, which is a steeper angle than most
riders comfortably achieve. This higher-performance setting also allows
higher wheelies before power is reduced to bring them down.
Radial-mount Brembo calipers supply huge power despite their older-tech two-piece design.
And with the explosive clout from the RR’s potent powerplant,
wheelies happen frequently, even more so on the 2012 model because of
its lower gearing via an additional tooth on the rear sprocket, which
plays a part in the 10mm wheelbase reduction. The front end dances
upward even in fourth gear at 135 mph, making me glad the newly
adjustable steering damper was set to position 8 of 10 to keep the
pucker factor down.
The S1000 nudges 160 mph on the front straight before a rider needs
to bleed off speed for Turn 1. Pushing my braking point a bit later, I
hammered the powerful Brembos and was met with some ABS intervention
through the front lever as the rear wheel was lifting off the ground,
which is as the Race ABS intends in Race mode. Its unexpectedness caused
a bit of a fright, but it’s a condition that can be averted by
switching to the ultra-performance Slick mode or disabling the ABS.
| A Weighty Solution |
| Little known fact: In 2009, during its inaugural season in World
Superbike competition, BMW was having difficulties getting the S1000RR
to hook up when driving out of corners. So, seven months after beginning
series production of the S1000, BMW added approximately a pound of
weight to its crankshaft with the intent of enhancing driveability of
the WSB weapon. BMW engineers tell us not much difference could be felt
on the streetbike, but it did aid the racebike, which has to use a stock
crankshaft. |
Slick Is Quick
Slick mode allows fast riders to push the machine’s limits, allowing
up to a dizzying 53 degrees of lean angle before throttle application
intervention, and the traction-control setting permits a fair amount of
rear-tire drift to help steer the bike during corner exits. And
intervention from the TC is smooth despite considerable rear slip. The
DTC is reassuring and really aids confidence on corner exits. If you’re
especially brave, DTC can be disabled with a long push of a single
button. It’s worth noting here that not one of the S1000RRs hit the deck
due to a loss in traction.
With a cooperative chassis and electronic rider aids, the S1000RR makes it easy to get up to speed quickly.
The heady mill in the RR provided bigger thrills during bigger and
longer wheelies (up to 5 secs), and the awesome acceleration was
enhanced by BMW’s optional quickshifter that allows full-throttle,
clutchless upshifts an instant before smacking into a 14,200-rpm rev
limiter. The bike’s voracity for inhaling straightaways is absolutely
mind-bending for anyone not racing a Superbike.
After getting accustomed to riding near the speed of light, I finally
had a chance to notice the revised instrumentation. The prominently
placed analog tach has larger numbers on its white face for easier
reading, augmented by the returning white shift light. The LCD info
screen can now be set of one of five brightness displays. Also new is a
“best lap in progress” indicator that responds every 100 meters to tell a
rider if he’s on a pace quicker than the previous quickest lap.
In the corners, it’s difficult to say for certain if the new RR has
the improved steering accuracy and feedback promised via its chassis
changes, but I honestly had zero quibbles about its responsiveness and
precision. It obediently goes where it’s pointed, and it feels stable
and communicative when carving around an apex. Also commendable was the
non-existence of major setup issues, as all the riders I polled weren’t
bothering to mess with significant suspension adjustments.
 Picking a precise line is easy on the S1000RR.

The Verdict
Well, since BMW’s uber-bike was already a standout in its class, it
shouldn’t be a surprise to find out this slightly improved model gets a
very high rating. The class-dominating S1000RR is now even more potent
and usable for 2012. And after getting to know the engineering and
testing brain trust behind the RR, I’m fully confident they’ll never
take a backward step.
Pricing has yet to be determined, but with the aggressive MSRP of the
previous version ($13,950 base) and continual elevation of prices among
the Japanese competition, the S1000RR might be a relative bargain.
After all, how many thousands would you have to spend to get another 30
hp from a Yamaha R1…?
