You would be correct. Loncin has been OEMing the bimmer 650 thumper for some years now. Somehow I think Austrian engine maker/designer AVL is involved, or was in the earlier years before Loncin took on full responsibility. This is not the engine that goes into the F650GS, which is a twin that's probably still made in Germany. That engine, as we've discussed before, is actually not a 650cc at all, but is the same displacement as the F800GS -- the same engine block. It's the G650GS that uses the Loncin-made engine.
The engine you are referring to is the 652cc single which went into all F650 BMW bikes pre 2008 and into all G650s after 2008. It was developed by Rotax in Austria with and for BMW as is the 798cc parallel twin which sits in all 2008 and later F650s and F800s.Quote:

AVL from Austria is the developer of the 597cc engine which sits in the JH600s.
Dear Andy,
Yes, it's Rotax not AVL that supplies the thumper engine technology to Loncin for the G650GS. Thanks for the correction.
Do you understand BMW's logic for using the same 798cc engine in both the F800 and F650? Perhaps a different crankshaft with a shorter throw so the 650 displaces a smaller volume? Why bother offering an F650 twin if it's really an 800? Weirdness from the marketing department, I suspect.
cheers!
There is a lot of confusion about BMW's naming convention and I personally haven't yet found any reasonable explanation.Quote:

F650GS: 52 kW (71 hp) at 7,000 rpm (output reduction to 25 kW (34 hp) at 5,000 rpm possible)
F800GS: 63 kW (85 hp) at 7,500 rpm
F800ST: 62.5 kW (85 hp) at 8,000 rpm (output reduction to 25 kW (34 hp) at 7,000 rpm possible)
F800R: 64 kW (87 hp) at 8,000 rpm (output reduction 25 kW (34 hp) at 6,000 rpm possible
F800S: 62.5 kW (85 hp) at 8,000 rpm (output reduction to 25 kW (34 hp) at 7,000 rpm possible)
The output reduction is useful in some markets where new riders are facing power and power/weight ratio limitations.
Still, the name 650 is weird, confusing, strange, a myth, ... :confused1::confused1::confused1:
Hey, I prefer thumpers anyway!Quote:
