Sold right alongside BMW's new
dual-purpose single will be its fraternal twin, the F650 Street. As the name
implies, this is a more street-oriented version of the F650. Both bikes share
spoke wheels, but the ST uses an 18-inch front rim, one inch smaller than the
F650. The result is quicker steering and a lower seat height for the ST. Tires
are chosen purely for road work, with a set of Metzeler street tires replacing
the F650's enduro rubber. Other differences include a lower windscreen on the
ST, designed to function more effectively at higher speeds (although the F650's
taller screen will bolt right on the ST).
The ST's handlebars are narrower,
allowing a more tucked-in position for freeway riding while the F650's wider
bars allow more leverage off-road. Front fender design differs between the two
bikes as well. A higher unit is fitted to the F650 to provide more clearance for
dirt and mud, and side extensions cover the lower fork legs to protect them from
stones chips. Also offering more protection is the F650's front engine plate
which tucks in tighter to protect the engine, while the ST's functions more as
an aerodynamic spoiler.
All of the options available for the F650 can be fitted to
the F650ST.
