Background – The BMW K1300S

BMW announced updates to the K 1200 series at the 2008 Intermot show in Germany. They sent us 85 pages (!) of information covering the BMW K 1300 S, BMW K 1300 GT and BMW K 1300 R, with even a little S 1000 RR thrown in for good measure.

This much information means that BMW is counting on this as a major release. But. we can’t help but wonder if this is a case of too much, too late?

With the global economic meltdown of 2008, worldwide extreme fuel prices and the difficult loan situation in many countries, a $20k bike with a 1300 cc engine may not be the best strategy. Meanwhile, at least in North America, dealers are completely sold out of smaller, fuel-efficient 125 cc to 500 cc motorcycles for the first time in decades, due to the new riders coming online and high fuel prices motivating buyers to look for MPG rather than HP.

In any case, the production schedule for the new K 1300 series was probably set several years ago, so there isn’t much that BMW can do about it. And 1300 cc should be quite a kick. may as well go down in flames as the world comes to an end!

Here is an edited version of their information on the revised K 1300 S; we’ll follow up with the rest of the new K 1300 series as soon as we can wade through the rest of the 85-page press release covering these new models.

BMW K 1300 S

The New BMW K 1300 Series

The significantly updated and upgraded successor to the BMW K 1200 S is proudly celebrating its world debut at the 2008 INTERMOT motorcycle show: the new K 1300 S, the most powerful and fastest BMW the world has ever

seen.

As a milestone in the BMW Sports Encounter World and with engine output of 129 kW (175 hp) combined with overall weight of 254 kg (560 lb) including fuel, this truly supreme motorcycle offers the utmost in dynamic performance and sporting riding features. Launching this new model, Europe’s largest and most successful motorcycle manufacturer is once again increasing its leadership in the topmost class of sporting high-performance machines.

Conceived consistently as a sports machine, the K 1300 S has not only maintained, but in many areas even enhanced the qualities of its predecessor. As a result, this new high-performer combines fascinating and innovative technology of the highest caliber with outstanding all-round qualities and safety.

On the road this means even greater riding precision and agility, even more dynamic power and performance, and, at the same time, the superior safety and ease of control in all situations so typical of a BMW.

Like its predecessor, the K 1300 S does not make any compromises, but rather brings together even more consistently than before all the virtues of the most dynamic motorcycle in the K-Series: sporting and dynamic performance combined with superior comfort, playful and easy handling.

This is also enhanced with absolute riding stability, supreme top performance in conjunction with perfect everyday riding qualities, an even more slender and sporting look with optimized protection from wind and weather, plus sophisticated ergonomics.

Taking up a great tradition of BMW Motorrad, the new K 1300 S stands out through qualities typical of BMW such as a long service life, ease of maintenance, optimum emission management by means of a fully controlled three-way catalytic converter as well as maximum active safety when applying the brakes ensured through the most progressive brake system currently available in the market: BMW Motorrad Integral ABS featured as standard.

As in the past, BMW, through the K 1300 S, offers the only sports motorcycle in this segment with a maintenance-free drive shaft.

Featuring innovative top-end technology, optimum riding qualities, an even more dynamic look and performance enhanced to an unprecedented standard, the K 1300 S impressively renders the BMW Sports Encounter World, clearly maintaining BMW’s strong leadership in the upper sports segment.

The main objective in developing the new K 1300 S was to create an even more supreme motorcycle with enhanced riding qualities ensured by an even more powerful and harmonious torque curve and a higher standard of riding comfort.

Increasing engine capacity to 1,293 cc while maintaining maximum engine speed of 11,000 rpm ultimately led to a significant improvement of performance, power and torque. In its fundamental qualities, the K 1300 S is based on the proven drivetrain configuration and engine arrangement of its predecessor, using the existing advantage of a low centre of gravity made possible by the extreme angle of the cylinder bank tilted 55° to the front and allowing very low arrangement of the engine.

At the same time the new K 1300 S benefits from the very slender engine block allowing a very low angle in bends for a truly sporting and dynamic style of riding.

In its suspension and running gear the new K 1300 S – by far the lightest 1,300-cc model in this segment at 228 kg/503 lb dry weight – applies a successful concept combined with proven modules and components. One example in this context is the extra-low V-shaped radiator interacting with the wheel supports to provide an ideal configuration of the frame above the cylinder head and, as a result, reducing the overall width of the machine.

And with the frame profiles merging smoothly at the rear, the K 1300 S enables the driver to hold his knees tightly together, ensuring optimum contact with the motorcycle under all conditions. The active, dynamic and forward-looking seating position is tailored fully to the rider, but nevertheless allows a relaxed and comfortable style of motorcycling at all times.

So while being unusually dynamic and sporting, the K 1300 S is almost playful and certainly very safe in its behavior, guaranteeing stress-free riding pleasure even in sporting style. Innovations on the running gear and electronics. The upgraded front-wheel Duolever suspension makes a significant contribution to the outstanding riding qualities of the K 1300 S.

The newly developed, lower longitudinal arm now made of a forged aluminum alloy ensures an even more sensitive and transparent response, further enhancing the leadership of BMW Motorrad in the area of suspension technology.

The spring/damper set-up is firmer than before also in the interest of even better feedback. The K 1300 S is available with second-generation Electronic Suspension Adjustment (ESA II) as an option, a further development and improvement of the original ESA suspension introduced for the first time in series production on the K 1200 S.

Applying the most advanced CAN-bus technology, the progressive on-board network allows a wide range of functions and facilitates the diagnostic procedures usually required by intelligently connecting the machine’s electrical and electronic systems.

Second-Generation, 1300 cc Powerplant

The second generation of BMW Motorrad’s four-cylinder power units has been upgraded and updated in the interest of even more power and performance, extra torque, and supreme riding dynamics.

Displacement of the four-cylinder inline power unit in the K 1300 S is up by 136 cc from 1,157 cc to 1,293 cc. Maximum output is 129 kW (175 hp) at 9,250 rpm, maximum torque of 140 Newton-meters or 103 lb-ft comes at 8,250 rpm.

In absolute figures, this is an increase in engine output by 6 kW (8 hp) and an increase in peak torque by 10 Newton-meters (7.4 lb-ft). While the former K 1200 S had to be revved up to 10,250 rpm to develop its maximum output, the power unit of the new K 1300 S develops its maximum power at a relatively low 9,250 rpm.

A further significant advantage is that more than 70 per cent of the engine’s maximum torque is available from just 3,000 rpm, with 10 Newton-meters or 7.4 lb-ft more torque available all the way from 2,000–8,000 rpm versus the K 1200 S.

The objective in developing the new model was obviously to enhance the already high standard of riding dynamics and sporting characteristics through power and performance easy to handle at all times. And weighing 82.8 kilos/182.6 (K 1200 S: 81.3 kilos/179.3, in each case including the clutch, gearbox and oil), the upgraded power unit of the K 1300 S remains one of the lightest engines of its size in the market.

Like the previous model, the K 1300 S benefits above all from its carefully conceived overall configuration as well as the space-saving arrangement of ancillary units and the integrated gearbox. In all, this makes the entire drivetrain very compact, with ideal concentration of all masses in the middle of the machine.

And as on the K 1200 S, the overall width of the power unit, measured on the level of the crankshaft, is 430 millimeters or 16.9. The perfect interaction of technical solutions and optimum integration of the engine and running gear already featured on the K 1200 S is fully retained on the K 1300 S.

BMW K1300S

In the process of upgrading the power unit of the K 1300 S, the engineers at BMW Motorrad have given particular emphasis to supreme riding qualities. Hence, the combustion chambers on the four-cylinder, the intake camshaft angle and the valve timing as well as the stroke of the outlet valves have been modified accordingly, with the outlet valve springs being re-set from the ground up.

Running in anti-friction bearings, the connecting rods are extra-light forged components made of heat-treated steel. Measuring 119 millimeters or 4.68 in length (K 1200 S: 120 mm/4.72), they keep lateral forces acting on the pistons to a minimum and guarantee superior engine refinement despite the longer stroke.

Together with their anti-friction bearings, the conrods weigh just 404 grams (K 1200 S: 413 grams). In usual BMW style, the upper conrod opening comes with a bearing bush conceived for a service life of more than 100,000 kilometers or 61,000 miles.

Newly developed lightweight box-type pistons measuring 80 millimeters or 3.15 in diameter, with a short piston apron and two slender piston rings optimized for minimum friction as well as a slender oil scraper ring, serve to increase cylinder stroke and, accordingly, the capacity of the engine.

Balance Shafts for Engine Smoothness

The balance shafts turn twice as fast as the crankshaft. To minimize any noise or sound waves generated in the process, the balance weights are connected to the balance shafts by means of elastomer units.

Split horizontally along the middle of the crankshaft, the cylinder crankcase is made of a high-strength aluminum alloy. Made of a die-casting, the compact upper section forms an extra-stiff composite unit comprising the four cylinders and the upper bearing support for the crankshaft.

Dry Sump Oil Supply

The K 1300 S features dry sump lubrication introduced on the K 1200 S and proven over many years – the same technology as is largely used on racing engines.

Apart from superior operating qualities and reliability even under extreme conditions, dry sump technology quite unique in this segment keeps the crankcase low and flat and therefore ensures a low position of the engine and a low centre of gravity.

By leaving out the usual oil sump, the entire engine may be fitted 60 millimeters or 2.36 lower down than a conventional power unit.

The oil reservoir comes in a tank fitted in the frame triangle behind the engine. A dual oil pump operating at the rear of the crankcase and driven by a chain from the clutch shaft draws in lubricant from the oil reservoir and feeds the compressed oil first to the oil filter (main flow filter).

Easily and conveniently accessible from outside, the oil filter is positioned on the lower left side of the crankcase. From there the compressed oil flows into the main oil pipe in the crankcase and is spread out through internal holes to the lubricating points.

The oil flowing back, in turn, gathers at the lowest point in the crankcase formed by a bulge in the lower lid. The second pump then delivers the oil flowing back first to the oil cooler and from there to the oil tank, forming a reflow system patented by BMW.

The larger oil cooler is integrated beneath the headlight in the aerodynamically optimized front fairing for superior aerodynamics. In the interest of consistent lightweight technology, finally, the oil cooler pipes are made of aluminum.

The oil level is checked conveniently and easily by means of a transparent plastic pipe at the outside of the oil reservoir. This patented hose-like pipe also serves to drain oil from the tank during maintenance. Capacity of the oil tank is 4.2 liters or 0.92 imp gals.

An oil level warning system is available as an option in conjunction with the likewise optional on-board computer.

Optimum Location for Ancillary Units

To keep the engine as slender and compact as possible, the electrical ancillaries and their drive units are fitted behind the crankshaft in the open space above the gearbox. The alternator, in turn, is driven by the primary gear on the clutch, developing maximum output of 580 W and maximum electric power of 50 Amps.

The pre-shaft starter is connected to the engine by a freewheel drive unit operating on the alternator drive gear. Power transmission – reinforced multi-disc oil bath clutch, optimized cassette gearbox and HP Gearshift Assistant.

Gearbox and Shifting – The BMW Gearshift Assistant

The gearbox has been upgraded and modified for the new K 1300 S, with the shift forks, the shape of the dog-shift units and the geometry of the gears themselves being optimized in the process. The gears are now contoured

differently at the rear and the shift forks come with a three-point rest replacing the former two-point base.

To reduce weight, the hollow shift cylinder is made of high-strength aluminum alloy and runs in anti-friction bearings. The shift forks are made of steel and are lubricated by compressed oil.

To reduce the length of the gearbox, the two gearbox shafts are positioned above one another. The gears themselves are in straight-tooth configuration benefiting not only the degree of efficiency but also the overall width of the gearbox.

The K 1300 S features a new shift lever with an ergonomically optimized pivot point. Together with the likewise new anti-friction bearing for the shift lever this ensures an even more precise and faster gearshift than before. At the same time gearshift travel is even shorter and more dynamic.

For the first time in the history of large-scale motorcycle production by BMW and, indeed, for the first time in series production worldwide, the rider of the K 1300 S is able to shift up with the help of the optional HP Gearshift Assistant without operating the clutch and, accordingly, without the slightest interruption of traction and pulling force.

To perform this operation the ignition and fuel supply are interrupted for fractions of a second in the shift process. The HP Gearshift Assistant introduced for the first time on the HP2 Sport comes together with the sports footrests available as special equipment. Shaft drive to the rear wheel – optimized and quite unique in the sports segment.
