R 1200 CL Engine The proven 1200 cc R 259 variant, with high-camshaft-valve control and four valves is fitted in the R 1200 CL unchanged. The engine cooling system is handled by twin oil-coolers integrated in the front frame. Oil circulation is supplied by its own oil pump, regulated by a thermostat.The oil flows through both oil coolers in succession; lubricating oil and cooling oil are separated. Engine management is controlled by the Motronic MA 2.4. in conjunction with the performance-determining components, such s camshafts, valve sizes, air intake design, the R 1200 CL engine is also designed in such a 4 way that a torque range desired for a luxury Cruiser is attained. The engine output of the R 1200 CL is 45 KW (61 bhp) at 5000 RPM, the maximum torque 98 Nm (71 ft/lb) at 3000 RPM. The engine’s displacement and dynamic specifications are: Displacement = 1170 cc Bore x Stroke = 101 mm x 73 mm Pistons = short skirt light alloy box piston Compression Ratio = 10.0:1, Camshaft profile = 256° The exhaust system is designed according to the bikes cruiser characteristic. Technical Features in Detail
R 1200 CL Engine The two piece light alloy crankcase is manufactured using a pressure die-casting method.The oil pan, which holds 3.75 litres, is integrated into the engine case halves. As with all R Series bikes, the engine and gearbox is a combined load bearing element of the chassis. For this reason, both case halves were designed with a specific rigidity with the aid of computer calculations of the Finite Element Method. The 1-piece forged crankshaft is accommodated centrally in the crankcase on sliding bearings. It runs on two bearings, the rear bearing being larger and designed as a double collar bearing. The 125 mm long connecting rods are made of sintered steel and are cracked at the big end. The weight-optimized box pistons are made of light alloy and have machined valve notches on the piston crown. A pressure release channel above the piston ring zone prevents a partial vacuum from building up in the combustion chamber during engine cool down to prevent oil from being pulled in under vacuum when the engine is off. The camshafts are mounted into the cylinder heads by separate camshaft carriers. The cams are made up of a case-hardened shaft with pressed-on individual cams made of sintered material. The camshafts are roller chain driven at a 2:1 ratio geared down by the auxiliary shaft, which is located below the crankshaft and also drives both duo-centric oil pumps. The valves all have 5 mm valve stems.They are actuated in pairs by clear chill cast tappets, short aluminum tappet push rods and forged valve lifters.
