In the past few weeks I’ve fielded some questions from a couple of my friends about the F650 GS. With the start of riding season coming up, there are a few motorcycles on the market that have caught their eye. The problem is that several years back BMW made it a little confusing for the uninitiated to figure out exactly what’s going on with the F650 GS.

First, let’s take a look at the original F650 GS. This machine, when introduced in 2000, was the successor to the original F650 Funduro from the mid-90s. It’s equipped with a 50hp, 652cc, single-cylinder, water cooled engine with 4 valves and dual overhead camshafts. In GS trim the F650 received a few new features. Probably the biggest change was moving the fuel tank under the seat. The “false tank” up front stored the oil tank, the airbox, and the battery. The body styling was also overhauled to a more modern design. Unlike the Rotax power plant in the Funduro, the engine production for the F650 GS was moved entirely in-house. The F650 GS was pretty advanced for a small-engined motorcycle of the time. It had a computer-controlled fuel injection system, a catalytic converter, ABS, and a tuned airbox. In 2004 the engine received twin spark plugs that improved the fuel economy and power output. It’s a great small motorcycle and perfect if you’re looking for your first bike or something that isn’t as big or bulky as a full-size motorcycle. Unfortunately, BMW discontinued the F650 GS at the end of 2007.

A brand-new replacement motorcycle arrived the following year and was named (wait for it) …the F650 GS. Wait, what? So, remember earlier when I said that it got a little confusing? This is the spot. Until this point, the “650” designation in the model name denoted the engine displacement. However, the new F650 was essentially the same as the larger F800 with a twin-cylinder 798cc engine, detuned to produce less power. But that original single-cylinder F650 wasn’t gone for long. A year after the twin-cylinder version, it returned as the G650 GS. It got a bit of a power bump in the new series as well as a few new features like heated grips and a stronger alternator.

Now, if you’ve got one of the original single-cylinder F650 GS motorcycles, or if you’re looking at getting one of these small dual-sports, you know that it probably needs some maintenance. After tens of thousands of faithful miles you might be dripping some fluids or have some busted pieces here and there.
