The BMW R 65 GS is an all-terrain motorcycle from the vehicle manufacturer BMW with a single-sided swing arm (monolever) and was produced in only 1,727 units from 1987 to 1992. It is the smallest BMW travel enduro and rounded off the GS model range of the time with the R 80 GS and R 100 GS . Officially, the motorcycle was only delivered with a 20 kW (27 hp) engine.
history
Due to the tier driving license valid from April 1, 1986 in Germany, newcomers to motorcycle driving licenses were allowed to drive a maximum of 27 HP motorcycles for two years. In order to be able to serve this target group in the GS area, the predecessor R 80 G / S was quickly equipped with the smaller 20 kW engine of the R 65 Type 247 E and thus the new R 65 GS model below the R 80 GS and R 100 GS created.
A significant part of the 1,727 units produced may have served as driving school and government vehicles (disaster control, emergency services, military).
Compared to the Japanese single-cylinder enduro bikes of the 27 hp class at the time, the R 65 GS was relatively expensive at DM 9,450. The difference in price to the R 80 GS up to 1990 of only DM 1,400 appears small with the same equipment. Ultimately, the R 65 GS failed to succeed in the market; it was withdrawn from the range in 1992 and replaced by a 20 kW / 27 PS variant of the R 80 GS . "In the shadow of the new, enthusiastically received larger siblings, the smallest GS went under, even if the press did not criticize this machine."
properties
Compared to the larger GS models, the R 65 GS lagged behind in terms of comfort, among other things, it was not equipped with the better Paralever chassis. However, it is often overlooked that the disadvantages of the Monolever swing arm are less noticeable at lower torque and lower power.
Due to the specially developed 20 kW / 27 PS engine adopted from the R 65 , the R 65 GS has some technical features compared to the other BMW two-valve enduros, in particular with a 61.5 mm much smaller cylinder stroke, smaller valve diameter, smaller carburettors , a special camshaft with different timing and a larger rear axle ratio. “The BMW engine design went to great lengths to make the 20 kW variant of the R 65 shine with perfect engine characteristics. The result was convincing in operation: an engine that offered the buffalo characteristics that were so sorely lacking in the R 45. "
The special features mentioned lead to a comparatively high expenditure for a technically fundamentally possible conversion to a higher engine power.
Visually, the R 65 GS differs only slightly from the old R 80 G / S, among other things by a different paintwork and the chrome-plated exhaust.
