The BMW F series is a family of parallel-twin engine dual-sport motorcycles manufactured in Berlin, Germany by BMW Motorrad. Launched in 2008, the range comprises the F650GS, F700GS, F800GS, and F800GSA. In 2012 the F700GS replaced the discontinued F650GS, and in 2013 the F800GSA was introduced with a 24-litre (5.3 imp gal; 6.3 US gal) fuel tank and a larger front fairing and screen. The F800GT, and F800S both have belt drive.

Confusingly, and contrary to industry convention, each model's "number" does not refer to the engine capacity. Instead, each bike in the F-series range uses essentially the same 798 cc (48.7 cu in) engine, but with different power outputs and equipment levels. The parallel-twin engine was first used in the F800S, and is also used in the F800GT, F800R and F800ST, although these bikes are tuned to deliver peak power at a different RPM from the GS models. The GS models have longer suspension travel, needed for offroad use.

The F650GS name causes further confusion as it was previously used for a 652 cc (39.8 cu in) BMW bike fitted with a single-cylinder Rotax engine. It was produced from 2000–2007, then relaunched in 2009 as the G650GS, fitted with a Chinese-assembled engine of the same 652 cc capacity.

Model differences

As of March 2013, the main technical differences between the F800 and F700 are as follows:

Although all bikes use the same basic engine, the F800 produces 85 hp (63 kW), which is 10 hp (7.5 kW) more power than the F700 and 14 hp (10 kW) more than the discontinued F650. Engines on both the F800 and F700 can be modified to deliver a reduced power output of 35 kW (47 hp) for European riders on restricted Category A2 licences.

The F800 and F700 are fitted with twin brake discs on the front while the F650 was fitted with one disc. Both bikes had anti-lock brakes (ABS), which were optional on the F800 before 2013 models and all years of the F650.

Previously, only the F650 had the option of lowered suspension, which was not available on F800 models up to 2012. From 2013 both the F800 and F700 can be specified with a low seat and/or lowered suspension, the combination of which reduces seat height to 820–850 mm (32–33 in) (F800) or 765–790 mm (30.1–31.1 in) (F700), and makes the bikes suitable for shorter riders.

2013 update

The F800GS was refreshed for the 2013 model year, and the F700GS replaced the F650GS. Changes for 2013 included: power increases of 3.0 kW (4 hp) and 2 N·m (1.5 lbf·ft) on the F700 compared to the F650; standard ABS on all models and twin disc brakes on the F700; introduction of optional Electronic Suspension Adjustment (ESA) and Automatic Stability Control (F800 only); new generation handlebar switches and controls; updated instrument dials and standard fuel/temperature gauges; smoke grey turn indicators and rear LED light; new front fairings and paint finishes; and lowered suspension available for the first time on F800.
