On my 2011 Tenere the reserve is huge. The manual has it at 6.7 litres (a whole UK gallon and a half!) which makes the main tank 16.3 (giving a combined total of 23 litres).

My experience is the gauge starts flashing at the right time � giving you potentially 100 miles of reserve. When I�ve filled it up shortly after it zero�d I only managed to get in 17 litres.
