There have been drastic changes in the requirements for individual mobility concepts, specifically for conurbations. The challenges facing inner city traffic in future will be growing traffic volume, rising energy costs, and greater stringency of CO2 stipulations.
The BMW Group has recognised these challenges and is developing series solutions for the mobility needs of today and tomorrow.
As its first offers in this sector, BMW Motorrad had presented two premium vehicles on the maxi scooter segment. The BMW C 600 Sport and the BMW C 650 GT combine the outstanding riding properties of a motorcycle with the specific agility and conceptual comfort of a scooter for a new kind of dynamic riding experience.
POWERPLANT & TRANSMISSION
The 2-cylinder inline engine of the C 600 Sport and C 650 GT is an all new development by BMW Motorrad with a displacement of 647 cc. In both models, its rated power output is 44 kW (60 hp) at 7500 rpm, and its max torque of 66 Nm is available at 6000 rpm. The power is transferred via a directly integrated CVT, or continuously variable transmission.
The engine owes its low position and therefore low centre of gravity to its cylinder bank, which is inclined to the front through 70°. The characteristic sound and low vibration levels are the result of the 90° crank pin offset, 270° ignition spacing, and two balancer shafts driven by spur gears.
An electronic fuel injection system supplies the four valves under the two overhead camshafts. Oil is supplied from a dry sump with double oil pump, and an efficient cooling concept optimises the thermal equilibrium in the 2-cylinder engine.
The exhaust system is made completely of stainless steel and complies with motorcycle specifications. Fitted with a closed loop catalytic converter and an oxygen sensor, the C600 Sport and C650 GT fulfill today the Euro-4 emission limits of tomorrow.
SUSPENSION AND HANDLING:
One objective in the development of the C 600 Sport and C 650 GT was to combine directional stability at high speeds on the motorway with playful handling in city traffic and clear feedback to the rider – just like a motorcycle.
Accordingly, the design of the C 600 Sport and C 650 GT suspension features a torsionally rigid hybrid interconnection of a tubular steel bridge frame and a diecast aluminium unit at the swingarm bearing. In addition, the 2-cylinder inline engine functions as a bearing element, presenting a particularly rigid construction for stable and high precision response.
The greatest possible riding stability is also provided by the bearing for the cast light-alloy single swingarm with coaxial centre of rotation.
Also the suspension elements fulfil more fastidious needs for sporting character and comfort. At the front, an upside down fork presents a generous fixed fork diameter of 40 mm. The tail presents a reclining spring strut on the left side. The spring travels are each 115 mm, as they also occur quite commonly on the motorcycle sector. Also the tyre widths and cross sections of the C 600 Sport and the C 650 GT are aligned to motorcycle dimensions.
The new C600 Sport and C650GT are fitted with a generously sized braking system consisting of a two-rotor disc brake at the front and a single disc brake at the rear, each 270 mm [10.6 in.] in diameter. At the same time, the BMW Motorrad ABS fitted as standard ensures maximum possible safety.
WORLD PREMIERE FLEX CASE:
The FlexCase for the C 600 Sport is an innovative stowage space concept.
A flap in the tail base under the seat enlarges the stowage space on the stationary vehicle. This can be used e.g. to hold two helmets.
The differences between the C600 Sport and the C650GT at a glance:
The sporty, dynamic scooter BMW C600 Sport is characterized by a seat positioned for extremely active riding. This was made possible by the arrangement of the foot boards, seat, and handlebar in an ergonomic triangle. More fastidious needs for touring and long distance capabilities, on the other hand, are fulfilled by the luxurious C650GT. The rider and passenger can therefore adopt a more relaxed sitting posture that is highly appreciated especially over long stretches. The ergonomics designed for even greater passenger capability and comfort can be felt in particular on a more comfortable seat with adjustable backrest for the rider in conjunction with a higher handlebar and comfortable floor boards in lieu of separate footrests for the passenger. In addition, the C650GT presents a larger, powered windscreen for even better protection against wind and weather
