2021 BMW S 1000 R | Lighter new chassis and engine

2021 BMW S 1000 R

BMW revealed a new generation S 1000 R overnight and while peak power remains the same at 165 horsepower, BMW report significant gains have been made in regards to mid-range torque in what they claim is a ‘completely new four-cylinder engine based on the RR engine’. ShiftCam technology has not yet been employed on the S 1000 R but engine drag control (MSR) has made it on to the options list.

The cam-shafts are now powered directly from the crankshaft – the previous idler gear is no longer necessary. The intermediate gear for halving the engine speed is now located directly inside the cylinder head. What is more, the oil and water pump are combined to form a compact module. This gives the new engine an even tidier look.

The engine has been made more compact and lighter

In the new design, it was also possible to reduce the tubing for the water and oil cooling circuit to a minimum, as well as achieving a high level of impact resilience. In order to reduce overall width by more than 12 mm as compared to the predecessor model, there is now only one gear-wheel on the crankshaft, since the intermediate gear of the starter motor engages directly with the clutch gear or primary gear. The starter motor has been integrated on the top of the housing behind the cylinders. The crankshaft position is now detected via the alternator. In order to reduce the overall height of the engine, the length of the 10 per cent lighter heat-treated steel rods was also reduced by 4 mm to 99 mm.  As a result of these comprehensive measures, the new engine weighs a total of 5 kg less than its predecessor.

Fully sequential, cylinders elective fuel injection with two injectors per cylinder.

Maximum torque of 114Nm is available at 9,250rpm with more than 90 Nm of torque available from 5500 rpm and 80 Nm being delivered to the rear wheel from as low as 3000 rpm.  The upper three gears now sport longer ratios for more relaxed highway cruising.

Much lighter and more compact engine with hollow-bored titanium intake valves and speed-resistant rocker arms.

The S 1000 R had shed five-kilograms thanks to a new frame and myriad of other changes aimed at improving what was an already impressive package.  The frame and under-slung swingarm are based on the S 1000 RR and have been made considerably lighter than those of the previous generation model.

Gear shift action is claimed to be improved and lighter slip-assist clutch employed

The new S 1000 R is equipped as standard with Dynamic Traction Control DTC, ABS Pro with banking angle optimisation and the three riding modes: “Rain”, “Road” and “Dynamic”. Shift Assist Pro is optional.

New frame is of a very narrow design. In the area relevant for achieving good knee grip, it reduces the width of the motorcycle considerably by 13 to 30 mm. The ergonomic triangle has been shifted forward by about 15 mm, giving the rider a noticeably more front-wheel-oriented position.

With “Riding Modes Pro”, the new S 1000 R also features the “Engine Brake” function in conjunction with the engine drag torque control (MSR) and the “Power Wheelie” function which allows for monos while still retaining the other aspects of the traction control system. A new six-axis sensor has further sped and refined the response of all the safety aids.

The geometry is strongly based on the S 1000 R. The steering head angle has been changed from 65.2° to 66° with a correspondingly adjusted offset of the fork bridges, thereby making the angle steeper. The castor is thus slightly reduced to 96.3 mm (previously 98.5 mm). However, the wheelbase increases from 1439 to 1450 mm due to the longer swingarm. The range of steering lock has been increased by 5°

The new S 1000 R takes on the 6.5-inch TFT instrument cluster of the S 1000 RR. The rider can choose between customised screen displays for various purposes. The Pure Ride Screen, for example, provides all necessary information for normal road riding, while a further Core Screen shows displays for banking angle, deceleration and traction control.

The new S 1000 R adopts the 6.5 inch TFT display as used on the S 1000 RR.

A Bluetooth smartphone interface, which allows app-based arrow navigation, is already included as standard. The TFT display is operated from the handlebars using the multi-controller, while the optional M package provides a third Core Screen with bar display and lap timer.

The underslung swinging arm was taken from the S 1000 RR. It is a single-section chill cast part. The spring strut, which has a 20 % more stroke, is now located much further away from the swinging pivot axis

A striking new LED main headlamp and newly designed turn indicator and rear lights are also LED. The rear turn indicators have been adopted from the S 1000 RR and feature an integrated tail/brake light function. Enhanced safety when riding at night is ensured by the adaptive turning light, which is a component of Headlight Pro.

The adaptive turning light, which is unique in the mid-range, works by switching on additional LED elements in the main headlight that are fitted with their own reflectors, depending on the banking angle. It is activated from an inclined position of more than 7° and a speed of more than 10 km/h. The additional lighting effect can be experienced up to a banking angle of 25°.

In addition to the basic colour Racing Red non-metallic, the options Style Sport and the M package is available. If optioned with carbon rims and M package another 3.7 kilograms is shaved from the S 1000 R. The standard rims are already 1.8 kg lighter than before.

The new generation of Dynamic Damping Control, DDC, is available on the S 1000 R and its response linked to the riding modes. It is also completely customisable and a maximum damping setting selected for track work.  Tyre pressure monitoring is also optional.
