The BMW F 650 GS, Great Adventure Bike
The BMW F 650 GS, for reasons that nobody at BMW Thailand has been able to explain to my complete satisfaction, this BMW motorcycle is called an F 650 GS even though it's actually powered by an 798cc parallel twin, four-stroke engine. The engine of the BMW F 650 GS is basically a detuned version of the power-plant found in the BMW F 800 GS.Whatever reason BMW selected the F 650 GS name, the result is an impressive motorcycle that will find friends even among beginners to the adventure riding, the BMW F 650 GS provides a comfortable, relaxed riding position. Perhaps the gearing could be a bit shorter for more punch in the low rev-section and there's a bit of vibration at the top end of the rev range, but it's no big deal.
The BMW F 650 GS offers some hope for Asian riders, who are all too often ignored by non-Asian motorcycle manufacturers. As well as seat with height that can be set from only 790mm to a still reasonable 820mm, the optional factory-fitted lower suspension takes that down all the way to 765mm. Unfortunately, the small screen is only useful for Asian sized riders, too. Lucky alternative screens are available.
The BMW F 650 GS is powered by a liquid-cooled 798cc parallel twin, four valves per cylinder DOHC, with fuel-injection and digital ignition, capable of producing 70 horsepower at 7,000 rpm while 75 N.m torque at 4,500 rpm.
The BMW F 650 GS engine has proved to be pretty solid, but the detuning will make it even more reliable and tough. Valve timing, for example, should only need checking every 20,000 kilometer. Not that the BMW F 650 GS is equipped with a completely mild package. The parallel-twin BMW engine produces nearly 20 horsepower more than the single-cylinder BMW G 650 Xmoto with a price difference of only 51,000 Baht.
