*1000 cc Twin engine  
==History==
*5-speed transmission
Just a few years after introducing the [[BMW R90/6|BMW R90/6]] and [[BMW R90S|BMW R90S]], [[BMW|BMW]] upped the capacity of its range-topping flat-twins to 980cc for the 1977 season in the form of the '/7' series. The latter comprised the R100/7 tourer, which used the 60bhp version of the new engine, while the cockpit-faired R100S sportster and the fully faired [[BMW R100RS|R100RS]] superbike came with 70bhp on tap. Within a couple of years the R100/7 'naked' had been re-titled [[BMW R100T|R100T]] and gained an extra five horsepower, while the others - together with the new [[BMW R100RT|R100RT]] super-tourer - continued to use the 70bhp engine.
*Front Dual Disc Brakes






==Engine==
The engine was a [[air cooled]] air-cooled, four-stroke, boxer two cylinder, 2 valves per cylidner. A 94.0mm [[bore]] x 94.0mm [[stroke]] result in a [[displacement]] of just 980.0 cubic centimeters. Fuel was supplied via a overhead valves (ohv). 
==Drive==
The bike has a 5-speed, manual transmission. Power was moderated via the dry, single plate, diaphragm spring. 
==Chassis==
It came with a 3.25-19 front [[tire]] and a 4.00-18 rear tire. Stopping was achieved via dual 260mm discs, 2-piston calipers in the front and a 260mm drum in the rear. The front suspension was a  hydraulic telescopic fork while the rear was equipped with a dual adjustable shocks. The R 100 S was fitted with a 6.34 Gallon (24.00 Liters) fuel tank. The wheelbase was 57.72 inches (1466 mm) long. 
==1976 BMW R 100 S==
The 1976 MY BMW R 100 S has, at its heart, an air-cooled, four-stroke, 980cc, boxer twin cylinder powerhouse paired to a five-speed manual transmission that can produce a claimed 70 horsepower and 76 Nm of torque.
Standard fittings include a hydraulic telescopic fork as a front suspension, dual adjustable shocks in the rear, a dual seat, pillion grab rails, a small, nose-fairing with a windshield, an analogue instrumentation panel, dual front disc brakes coupled to a rear drum brake, die-cast aluminum wheels and a chromed, dual exhaust system.
==1977 BMW R 100 S==
[[Image:1977-BMW-R100RS.jpg|right|thumb|1977 BMW R100RS]]
The 1977 MY BMW R 100 S is a liter-class naked machine, that is sure to fit the taste for those riders who want superior performance. It comes with a hydraulic telescopic fork as a front suspension, dual adjustable shocks in the rear, a dual seat, pillion grab rails, a small, nose-fairing with a windshield, an analogue instrumentation panel, dual front disc brakes coupled to a rear drum brake, die-cast aluminum wheels and a chromed, dual exhaust system.
In the engine department, it sports a four-stroke, air-cooled, 980cc, two cylinder boxer powerplant mated to a five-speed manual transmission and can reach a maximum power output of 70 horsepower and 76 Nm of torque.
