BMW F 650 CS
The BMW F 650 CS Scarver is a motorcycle of the German car manufacturer BMW. The partially clad Tourer was introduced in Europe on 24 November 2001 and assembled from 2001 to 2005 at BMW's plant in Berlin Spandau. The abbreviation CS stands for City / Street, the sales name Scarver is a portmanteau of street and carver. The internal factory code is E650C, the model code K14.
The CS was the third model of the F - 650 series after the Enduro BMW F 650 (1993-2000 ) and the successor to the BMW F 650 GS ( 2000-2007) and how these powered by a single cylinder engine from Rotax. The motorcycle fell on its unusual design, the new motorcyclists and commuters in the target group of 20 - should appeal to 30 year olds.

Conception
The bike was the result of a collaboration of BMW with the Italian two-wheeler manufacturer Aprilia, and even though the CS is structurally almost identical to the Enduro BMW F 650 GS, it has some technical features such as a single-sided swingarm, a toothed belt drive, a modular luggage system and a storage compartment on a point at which there is usually the fuel tank.
The American David Robb, Vice President of BMW Motorrad Design from 1993 to 2012, designed the F 650 CS. The small transparent blue windshield appeared as inspired by the iMac G3. The handles on the rear and the tank made of translucent polycarbonate acted as a reference to the Apple style. The bike was in the four colors Azur Blue metallic, gold - orange metallic, Titanium and beluga blue. The side panel could be assembled either in body color or ordered in aluminum look and a blue or sepia - colored bench, so that a total of 24 combinations were possible.
The modularity was continued in the designated as Stuffbay storage compartment, which was supplied as standard with a small " soft bag " and could be optionally equipped with a tank bag. An equally fitting molded hard plastic container could be supplemented by two waterproof speakers with audio amplifier. The ignition key fits into all three different options for the storage compartment. The speedometer is coupled to the audio system and the volume adjusted according to the speed.
BMW traditionally built chain and gimbals in the secondary drive, but with the CS BMW decided for the first time for a belt drive because it offered a cost and weight advantage and is low maintenance. The advantages of a belt drive should make the bike more attractive to newcomers who have no experience or reservations about the mechanical maintenance work at a chain drive.
Distribution
The press reviews of motorcycle magazines were largely positive, some praised BMW for the entrepreneurial risk and the courage to break with traditional concepts and to develop new customer groups. However, it was also expressed fears that the BMW emblem alone would not justify the premium price of 16,000 DM. While motorcycles increased at nominal power and specialization in the early 2000s, the Scarver ran to meet this marketing trend and was intended for commuters, non-traditional riders, beginners, female and small riders.
The CS was part of the strategy of BMW, the reputation of a counter " old people's manufacturer" and to attract new customers. The chief designer David Robb said:
"If we want to offer something to new people we have to offer something new. "
"If we want to offer people something new, we need to offer something new. "
The large storage capacity and ease of use should the CS make it attractive also for motor scooter riders and commuters. BMW estimated the share of potential buyers who had previously not a motorcycle or drove at 40 %. The Scarver was the first designed for beginners tourer from BMW after BMW R 65, which was built from 1978 to 1984.
In 2002, the American motorcycle magazine Motorcyclist described the sales figures of the F 650 CS as a "perfect flop ", which together with other lightweight European bikes " languishing ", because Customers outside the home markets felt they were too expensive. The motorcycle magazine Motorrad introduced the Scarver in October 2007, # 4 on the " 20 biggest motorcycle -flop ".
Model succession
2005 F 650 CS was discontinued after only four years of construction. A year later, the BMW F 800 S was launched, but another motorcycle symbolizes class and less for beginners but rather to appeal to buyers who want to move up from their first motorcycle. The F 800 model series is powered by a twin-cylinder engine, and although the F 800 S divides the belt drive with the CS and its own technical innovations, has carried them away, neither the unusual design nor the unconventional functionality of the CS or provoked comments such as on the polarizing styling of CS.
Construction
Motor
With the single-cylinder engine from the Austrian Rotax supplier the F 650 CS was compared to superbikes the one- liter engine class, which were marketed at comparable prices, motorized below average. The liquid-cooled four-stroke engine produces of 652 cc capacity is rated at 37 kW (50 hp) and a maximum torque of 62 Nm at an engine speed of 5500 min -1. The cylinder has a bore of 100 mm diameter, the piston has a stroke of 83 mm and a compression ratio of 11.5:1. In the cylinder head rotate two chain-driven, overhead camshafts, which drive two intake and two exhaust valves. The fuel injection system is controlled by an electronic engine management system.
The bike accelerates in 5.1 seconds from 0 to 100 km / h and reaches a top speed of 175 km / h For the rapid acceleration at the traffic light and spirited drives through the city traffic the bike was so motorized sufficient.
Landing gear
The chassis consists of a newly designed steel tube frame made of square tubes, which also serves as an oil tank for the dry sump lubrication. The 2,5 liter lubricant of the dry sump lubrication flow, among other things by the two interconnected, more upper -scale features of the bridge frame. Sheet metal panels on the frame protect the rider from heat. The rear frame is bolted. The rear wheel is guided by a single swing arm made of aluminum, the front wheel of a telescopic fork with 41 mm standpipe diameter. The rather soft coordinated central spring strut can not be adjusted in preload and rebound.
At the front tire delayed a perforated disc with dual - piston caliper Brembo, rear disc brake with a single-piston caliper. The rear brake disc is mounted in the 17-inch cast rim. An optional anti -lock brake system controls the delay on both brakes. The delay of 100 km / h in the state requires a stopping distance of 39 meters.
The built- in secondary drive belt drive produces more power losses than chain drives, which are common in high-performance motorcycles. Since timing belt but unlike chains, which always require an easy game, are always tight, they do not suffer from chain hitting. The response of the CS in the drive train is therefore comparable to a shaft drive.
Electrical
The starter battery has a capacity of 12 Ah and supplies the electric starter. An alternator serves as an alternator and produces an electrical output of 400 watts for the supply of ignition and lighting system as well as the on-board electrics. An on-board computer in addition to the analog tachometer provides information on speed, mileage and time. High and low beams are achieved by two faint ellipsoid headlights.
Fuel supply
The fuel tank has a volume of 15 liters, including 4 liter reserve, and is positioned under the seat to keep the center of gravity low. The tank opening is located on the right rear side of the vehicle. The average fuel consumption is 3.7 liters per 100 km, the theoretical range just over 400 km. The manufacturer recommends the use of unleaded motor gasoline with an antiknock properties of at least 91 octane. The exhaust after-treatment is carried out by a fully controlled three -way catalytic converter and below the limit values for pollutants emission standard Euro -2. The exhaust system is made of polished stainless steel.
As an accessory heated grips, a 12V electrical outlet, a car alarm, a helmet ribbon for the dummy tank, a main stand and bags for the rear luggage rack were offered.
Reviews
" The conclusion is from a motorcycle tester, Novelties, rated for over 25 years, to say that the BMW F 650 CS is the most important motorcycle of the new millennium. Because it combines the typical BMW driving dynamics properties such as, easy maintenance, high value retention as well as advanced technology solutions and offers to the toothed belt -care, low-noise drive technology. "
" Stylistically unmistakably inspired by the shimmering - tone design, the trend computers that Scarver to finally lure youngsters from the computer on the bike. In addition to the unusual appearance spices up serving as the basis F 650 GS on an integrated in the tank dummy audio system. Technical features, the 54 -hp single essentially a toothed belt from the chain driven GS. But the boys - The target group was the 20 - to 30 -year-olds - will neither Robbie Williams left in the tank with an Apple motor ".
" The Scarver is accurate, handy and easy to drive. Of bends, hairpins, wide arches or dog people moving curves - no matter the Scarver make all curves mood. The only pity is that the fork during hard braking twists noticeable - a fork stabilizer as in the GS models would be useful. "
" The articulated via a lever system central spring strut offers virtually zero damping is tuned way too soft and can not even be adjusted in spring base. The revenge on uneven turf. The rear of rocks and pumps, and when it comes thick, the whole thing goes crashing down on the block. "
" When Landstraßentänzchen of the 193 -pound Scarver swirls ahead to set their own delicate steering inputs quickly into action and romps like a puppy through the area skew. And maintains this outrageous agility zügigerem pace, resulting in intricate combinations of turns increased concentration calls, because in order to maintain the chosen radius, the steering must be done sensitively.
