Information
BMW S1000RR is a race oriented sport bike initially made by BMW Motorrad to compete in the 2009 Superbike World Championship, that is now in commercial production. It was introduced in Munich in April 2008, and is powered by a 999 cc (61.0 cu in) four-cylinder engine redlined at 14,200 rpm.
BMW made 1,000 S1000RRs in 2009 to satisfy World Superbike homologation requirements, but expanded production for commercial sale of the bike in 2010. It has a standard anti-lock braking system, with an optional electronic traction control. As of 2016, it has a wet weight of 204 kg (450 lb), and produces 148.4 kW (199.0 hp; 201.8 PS) at 13,500 rpm. With 133.6 kW (179.2 hp; 181.6 PS) to the rear wheel, it was the most powerful motorcycle in the class on the dyno.
2009–2011
The S1000RR was released in 2009 and was considered the best-equipped sport bike in the 1000 cc category, and with a bore and stroke of 80.0 mm × 49.7 mm (3.1 in × 2.0 in), it also had the biggest bore in its class. The bike came factory fitted with ABS and dynamic traction control, a first for road-going superbike at the time. On top of this, it came standard with three riding modes (Wet, Sport and Race) with an additional riding mode (Slick) available only after connecting a dongle, that you received with the bike, to a special jack under the seat. It was also the first production motorcycle to offer an optional quick shifter. This is a clutchless shifter that allowed you to upshift with no clutch actuation even at full throttle. After the initial delivery of motorcycles the factory started shipping them with a software governor that limited RPM to 9000 for a short break in period that was later removed by the dealers. The 2011 bike remained unchanged, keeping the same livery options, engine, chassis and suspension.
2012
In 2012, the bike received slightly more significant changes. It was given new throttle maps for each of the four riding modes, to combat throttle response issues that customers were facing with the bike. To further aid this issue, BMW updated the throttle tube to be lighter and have a shorter pull. The intake and exhaust systems received updates: the ram air intake was made 20% larger and the catalytic converters were moved from the headers to the muffler, which allowed the oil sump heat shield to be removed, saving a small amount of weight. The optional DTC (Dynamic Traction Control) was updated, smoothing the butterfly valve action when a wheelie was detected, providing a less violent response to the bike’s front wheel lifting off the ground. The chassis was updated; the front suspension was lifted by 4 mm (0.2 in) and the rear was lowered by 5 mm (0.2 in). The wheelbase was reduced by nearly 10 mm (0.4 in) through a tooth addition in the rear sprocket (45). The angle of the steering head was revised and the offset of the fork was reduced by 2.5 mm (0.1 in). The triple clamp on top of the fork was uprated to forged aluminium. Lastly, the spring rates and valving in the suspension were revised, including special check valves to allow for completely independent compression and rebound adjustment, coupled with a 10-way adjustable steering damper. The 2012 visual updates included a new face of the tachometer as well as new heel plates, a slimmer-looking tail section and reshaped side panels with plastic winglets: these were said to improve aerodynamics at speed. Smaller visual updates included grilles on the side of the tank plastics and a new “RR” logo.
2013 and HP4
In 2013 the bike did not receive updates to the same extent as the 2012 bike. However, BMW introduced the HP4 variant, a more track-oriented version of the standard S1000RR. The 2013 HP4 saw the ride-by-wire system again taken to a level unseen outside of the WSBK and MotoGP. The HP4 was fitted with a Dynamic Dampening Control (DDC) system that updates and makes changes to the suspension every 11 milliseconds, responding to various sensors as well as throttle input and is adjustable on the fly, a first on any production motorcycle. The bike was given an electronic controlled interference pipe and acoustic valves, allowing air to flow into the exhaust and burn unused fuel as well as upgraded Brembo Monobloc brake calipers. The riding modes of the HP4 differ from the standard bike, in that it allows for all 144 kW (193 hp; 196 PS) to be accessed in four modes. The HP4 also introduced combined braking, meaning that in all modes except slick, the back brake is applied automatically when the rider applies the front brake. It was offered in multiple race kit packages, ranging from the stock claimed 144 kW (193 hp; 196 PS) of the S1000RR all the way up to a claimed 158 kW (212 hp; 215 PS). The 2013 HP4 was also equipped with more electronic features, launch control and pit-mode, all accessible from the controls on the handlebars. The bike was also given its own colorway and an HP4-specific tachometer face. Also available at extra cost was a competition and premium package which included HP carbon engine belly pan, side spoilers and trim, HP folding clutch and brake levers, HP adjustable rider footrests, standard forged wheels finished in Racing Blue Metallic, a decal kit, (optional) heated grips, a pillion rider kit and an anti-theft alarm.
2014 and HP4
The 2014 S1000RR saw some more minor updates and the first race-ABS as standard. The handlebars were also slightly modified, as well as some very minor changes to the fairings. The HP4 variant was sold for the second year with no major changes; available at extra cost was a premium package which included HP carbon engine spoiler and trim, HP folding clutch and brake levers, HP adjustable rider footrests, standard forged wheels finished in Racing Blue Metallic, a decal kit, heated grips, a pillion rider kit and an anti-theft alarm.
2015
In 2015, the S1000RR saw major updates and changes. Notably, the bike now weighed 4 kg (8.8 lb) less and gained 4.4 kW (5.9 hp; 6.0 PS) to a claimed output of 148 kW (198 hp; 201 PS). This was achieved through reshaping the ports, a new cam profile, lighter valves and shorter velocity stacks drawing from a larger airbox. An all-new exhaust has also been implemented, drawing from the previous years HP4, adding a controlled interference pipe and acoustic valves. More options made available in the 2015 variant were included in the “Dynamic Package” which included BMW’s Quickshift Assist Pro, allowing for clutchless up and downshifts. BMW also introduced a “Race Package” which gave the user DDC from the HP4, a “Pro” riding mode as well as launch control, a customizable pit limiter and cruise control. To the electronics, BMW again added smoother front wheel lift intervention and a new “User” mode, where the rider is able to customize some defined parameters, allowing for a fully personalized riding experience. More learnings from the HP4 include combined braking (automatically activating the rear brake when the front brake is applied), on-the-fly ABS and DTC control and lean angle sensors that provide a readout on the dash. The 2015 bikes lighter chassis consists of four individual aluminium cast pieces welded together with the engine tilted forward at a 32 degree angle and integrated as a load-bearing element. The fork overlap of the immersion tubes was reduced to 6 mm (0.2 in) and the steering head angle increased 0.5 degrees to 66.5 without any change in the yoke offset. The swingarm pivot point was lowered by 3 mm (0.1 in) and the wheelbase lengthened by 15 mm (0.6 in). The new chassis geometry provides increased rider feedback from the front end the rear wheel. The visual updates to the S1000RR were also vast, with the asymmetric headlights being swapped (high beam left, low beam right), a softer nose and all new colorways. The muffler was changed to a larger can, while the fairings became more aerodynamically advanced adding vents and slips to allow for better stability at high speed.
2017
In 2017, a non-street legal, track-only variant, the HP4 Race was added, made in a limited production run of 750 units.
