The most important features of the new G 650 X model series
at a glance:

•           Sporting and emotional design characterised in particular by lightweight features.

•           Fast-revving single-cylinder power unit developing maximum output of 39 kW (53 hp) at 7,000 rpm and peak torque of 60 Nm (44 lb-ft) at 5,250 rpm.

•           Crankshaft running in anti-friction bearings and an even lighter alternator reducing free mass forces.

•           DOHC valve drive with cup tappets and four valves.

•           Liquid cooling with an aluminium radiator.

•           Electronic BMS-C II engine management with intake manifold injection and dual ignition.  

•           Stainless-steel exhaust system with three-way catalytic converter and oxygen sensor.

•           Dry sump lubrication with the oil tank positioned appropriately for an ideal centre of gravity. 

•           Close-increment five-speed gearbox with secondary chain drive.

•           High-quality running gear components, eloxy-plated aluminium attachments.

•           Torsionally-rigid tubular bridge frame with bolted-on aluminium rear frame.   

•           Stable upside-down telescopic fork, fixed-position tube measuring 45 millimetres (1.77´´) in diameter.  

•           Light and highly stable two-unit cast-aluminium swing arm. 

•           Top-quality spring struts at the rear.  

•           Low unladen weight between 156 and 160 kg (344 and 353 lb).

•           Conified aluminium tubular handlebar.

•           Foot brake and gearshift levers made of forged aluminium. 

•           Fuel tank positioned beneath the seat for an ideal centre of gravity, with good access to the filler pipe. 

•           High-performance brake system with on-demand ABS as an option.

•           Model-specific range of accessories and optional features.

The new single-cylinder models were developed under the leadership of BMW in cooperation with Aprilia S.p.A., Noale, Italy (Piaggio Group). Production is by Aprilia in their North Italian Scorzè Plant, naturally fulfilling all of BMW’s strict quality standards. And as on the F 650 models, the power
unit comes from Austrian specialist Rotax, again following the specifications and requirements made by BMW Motorrad.

In their overall concept, the three new models, using largely the same parts and components on the engine and frame as well as the same main features, seek to offer a very different and distinctive character in each case.

Optimised in weight, power and performance – the single-cylinder power unit.

The truly convincing single-cylinder power unit already featured in the existing BMW F 650 model series – to this day the benchmark in its class in terms of refinement, smoothness, fuel economy, and emission control – sets the foundation for the engines in all new G 650 X models.

Reflecting the different sporting requirements and demands made of each model, a number of components have been modified to reduce the weight of the new motorcycles by approximately 2 kg, enhancing the engine’s fast-revving response and performance and boosting engine output by 2 kW. As a result, the power unit not only offers maximum output increased to 39 kW or 53 hp at 7,000 rpm and peak torque of 60 Nm or 44 lb-ft at 5,250 rpm, but also even more dynamic performance and a greater athletic character in every respect.

Even lighter than before, the alternator minimises the free mass weight of the entire crankdrive system running in anti-friction bearings, giving the single-cylinder even more spontaneous and athletic performance. The balance shaft serving to optimise smoothness and running refinement has been retained, with the new starter and alternator cover made of magnesium making a significant contribution to the lower weight of the engine. The redesigned four-valve cylinder head, finally, serves mainly to connect the power unit ideally to the frame and suspension as a load-bearing element.
