BMW S1000RR is a sport bike initially made by BMW Motorrad to compete in the 2009 Superbike World Championship,[1] that is now in commercial production. It was introduced in Munich in April 2008,[2] and is powered by a 999 cc (61.0 cu in) four-cylinder engine redlined at 14,200 rpm.[3]

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.[4] With 133.6 kW (179.2 hp; 181.6 PS) to the rear wheel, it is the most powerful motorcycle in the class on the dyno.[5]

2009–2011

2011 BMW S1000RR

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.[6] The 2011 bike remained unchanged, keeping the same livery options, engine, chassis and suspension.[7][8]

2012

In 2012, the bike received slightly more significant changes. It was given a new face of the tachometer as well as 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 also received updates, the ram air intake was made to be 20% larger, as well as moving the catalytic converters to the muffler from the headers. This allowed for the oil sump heat shield to be removed, saving a small amount of weight. The optional DTC (Dynamic Traction Control) was also updated, smoothing the butterfly valve action when a wheelie was detected, providing a less violent intervention to the bikes front wheel lifting off the ground. The chassis was also updated, with the front suspension being lifted by 4 mm (0.2 in) and the rear being dropped by 5 mm (0.2 in). The wheelbase was also reduced by nearly 10 mm (0.4 in) through a tooth addition in the rear sprocket (45). The angle of the steering head was also 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 also updated to a forged aluminium component. Lastly, the spring rates and valving in the suspension were overhauled, 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 new heel plates, a slimmer-looking tail section and reshaped side panels with plastic winglets said to improve aerodynamics at speed. Smaller visual updates included grilles on the side of the tank plastics and a new "RR" logo.[9]

2013 and HP4

In 2013 the bike did not receive the same level of updates of 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.[10] 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, heated grips, a pillion rider kit and an anti-theft alarm.[11]

2014 and HP4

2014 BMW S1000RR

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.[12] 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.[13]

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.[14] 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.[15] 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.[15]

2017

In 2017, a non-street legal, track-only variant, the HP4 Race was added, made in a limited production run of 750 units.

2019

The S1000RR received a full model change for 2019 at the November 2018 EICMA, Milan, Italy. The 999 cc (61.0 cu in) four-cylinder engine is entirely new, which is claimed to produce 152 kW (204 hp; 207 PS) at 13,500 rpm (up 4.5 kW (6.0 hp; 6.1 PS) from the previous iteration) and 113 N⋅m (83 lbf⋅ft) of torque at 11,000 rpm. This new engine employs BMW ShiftCam technology on the intake side, which varies intake valve timing and lift. The system has sliding concentric outer shafts, with two different cam profiles on them, on a splined inner shaft with the drive on one end. An ECU-controlled motor switches between low- and high-speed cams at 9,000 rpm in under 10 milliseconds, which produce soft, low-lift, short-duration cams for low-down and midrange torque, then a more aggressive profile cams for peak power production. The outer shafts are moved by a movable pin engaging in a cammed slot on the shaft, which slides the outer camshaft section left and right as needed. BMW claims the addition of this system gives the S1000RR a more linear torque curve than its predecessor.

Aside from power increase, the S1000RR’s engine gains a weight loss of nearly 4 kg (9 lb) and a more compact external design. This was achieved through the use of specialized parts, like hollow-bored titanium intake valves and new DLC rocker arms that are said to be 25% lighter. The camshafts are now directly powered by the crankshaft, thus eliminating the need for the previous idler gear. The water and oil pumps are combined into one component for a compact design. The exhaust system is also 1.28 kg (2.8 lb) lighter on the 2019 model, which contributes to a total 11 kg (24 lb) loss in comparison to its predecessor. This brings the overall curb weight of 197 kg (434 lb).

To harnessing the power output, BMW gave the S1000RR a package of electronics suite of rider aids, including ABS Pro (cornering ABS), Dynamic Traction Control (DTC), Dynamic Traction Control Wheelie Function, Shift Assistant Pro (which allows for clutchless up and downshifts), Hill Start Control (HSC), Launch Control and Pit Lane Limiter. There are four preset riding modes: "Rain", "Road", "Dynamic" and "Race", as well as three "Pro" modes, which can be custom tuned and come with a three-stage engine-braking adjustment.

The chassis has been revamped for the 2019 S1000RR, which is focusing on weight reduction while improving handling. The aluminium perimeter frame drops 1.28 kg (2.8 lb) of weight, now using the engine as more of a load-bearing unit and reducing width by 13 mm (0.51 in). With a focus on improving agility, BMW steepened the steering head angle to 66.9 degrees and reduced trail to 93.9 mm (3.70 in). The wheelbase has been increased by 9 mm (0.35 in). The front suspension is a 45 mm (1.77 in) inverted telescopic fork, which is decreased in size from 46 mm (1.81 in), that is claimed to optimize flex and midcorner feel. BMW Dynamic Damping Control (DDC) semi-active suspension is still available on the S1000RR as an option, which has been enhanced with updated damping settings. The fuel tank and seat design are now slimmer. The front fairing is narrower and more aerodynamic than its predecessor, also housing twin symmetrical LED headlights, with the intake directly centered at the front for optimum airflow. The instrumentation now uses a 6.5-inch TFT display, which has four preset settings.

The M package, the first of any BMW motorcycle, is available, which includes motorsport paint finish, M carbon fiber wheels, an M lightweight battery, M Chassis Kit with rear ride height adjustment and swingarm pivot, the M Sport seat and a "Pro" riding mode. The package reduces the weight further to 193.5 kg (427 lb).[16][17][18][19]
