The BMW F 800 R is an undisguised motorcycle from the German vehicle manufacturer BMW . The naked bike was produced at the BMW plant in Berlin-Spandau from 2009 until 2019 and is the third model in the F-800 series after the BMW F 800 S and BMW F 800 ST . The factory code is K73.
construction
Compared to the F 800 S, the R has no single-sided swing arm and no toothed belt in the secondary drive. Aisles four to six are shorter than the clad version. A modified throttle valve mechanism should improve the throttle response.
drive
The liquid-cooled two - cylinder engine from Rotax generates a nominal output of 66 kW (90 hp) and a maximum torque of 86 Nm at a speed of 6000 min −1 from a displacement of 798 cm³ . The two cylinders have a Ø 82 mm bore , the pistons have a stroke of 75.6 mm with a compression ratio of 12: 1. The ignition interval is 360 °. The cylinder head of the transversely mounted in- line engine has two chain-driven, overhead camshafts , which control two inlet and two outlet valves via bucket tappets .
The motorcycle accelerates from 0 to 100 km / h in 3.9 seconds and reaches a top speed of 210 km / h. In a test (1000 hp), the consumption was given as 3.6 l at a constant 90 and 4.8 l at a constant 120 km / h
landing gear
The chassis is built on an aluminum bridge frame . The front wheel is guided by a telescopic fork with a Ø 43 mm standpipe diameter and 125 mm travel. The rear section is screwed on. The two-arm swing arm made of cast aluminum has a directly hinged strut with 125 mm spring travel and travel-dependent damping. Spring preload and rebound damping are adjustable. The seat height can be adjusted from 77.5 to 82.5 cm.
The motorcycle decelerates at the front with double brake discs with a diameter of 320 mm and two-piston calipers and at the rear with a single brake disc with 265 mm and a single-piston caliper. The braking system is from Brembo and is supported by an anti-lock braking system as standard. The cast aluminum wheels measure 3.50 × 17 "at the front and 5.50 × 17" at the rear.
The dry weight is 177 kg, the maximum load is 206 kg and the total weight is 405 kg.
Power transmission
The claw-shift six-speed gearbox has short shift travel. The multi-disc clutch in the oil bath is operated mechanically. The power is transmitted to the rear wheel by means of an O-ring chain .
Electrics
The starter battery is mounted above the engine, has a capacity of 14 Ah and supplies the electric starter . The alternator , a three-phase generator , generates an electrical output of 400 watts.
Fuel supply
The fuel is prepared by an electronic injection and is regulated by an engine control system called BMS-K + . As with all motorcycles in the F series, the 16 liter fuel tank is located under the seat, which keeps the center of gravity low. The tank opening is on the right-hand side, level with the pillion seat. The average fuel consumption is 4.8 liters per 100 km at a speed of 120 km / h.
The manufacturer recommends using unleaded petrol with a knock resistance of at least 95 octane . The exhaust aftertreatment is carried out by a regulated three-way catalytic converter and is below the emission limit values of the Euro-3 emissions standard .
Revision 2015
In February 2015, BMW launched the facelifted F 800 R with the following changes:
- Headlights (now more symmetrical)
- an upside-down fork and the brake calipers of the double disc brakes are now mounted radially
- modified, less cranked handlebars
- Seat height has been reduced and footrests have been moved further forward
- revised engine tuning or translation (the first two gears now shorter), 3 hp more (90 instead of 87 hp)
The following special equipment options are possible:
- Automatic stability control ASC (Automatic Stability Control), electronic suspension adjustment ESA (Electronic Suspension Adjustment).
- Power reduction to 35 kW (48 PS)
Reviews
“The impression of a lively engine always remains, which, thanks to the shorter gear ratio of the upper three gears, develops a lot of temperament even at higher speeds. The best example: if you want to know how fast the R is running, you don't need to run too hard on the autobahn. In no time at all, the 798 turns into the red area and on to the limiter that kicks in at speedometer 220. "
"In view of the objectively offered performance, the Twin easily plays in the league of sporty multi-cylinders, and that with enthusiasm, character and a remarkable soundscape - sonorous humming in the low speed range, energetically out of the middle range, in which it is clearly nimble on tours Hammering the airbox. "
“The first gear has a long translation, the cable clutch cannot be adjusted without a problem, which means that we would have already fully mentioned the details that took getting used to in this first driving report. Elegant swing arm, final drive chain instead of belt as in the sisters F 800 S, F 800 ST. [...] The chassis is rock solid right up to sporty country road speeds. The handling cannot be called playful, the 180 mm rear tire is the limiting factor. 25 years ago, BMWs were despicably called rubber cows because of their soft suspension setup. Long gone. The F800 R is sporty and tight, maybe a little too sporty for bad back roads. "
