This is a resto-mod BMW R80G/S Paris Dakar. A restored and modified version of BMW’s ultimate adventure motorcycle. The bike that started it all, updated with 21st century suspension, brakes and electrical.
The donor bike for this build was a clean BMW R80ST from North Carolina. Sharing the same main frame as the original G/S the ST was the road going version of the adventure bike. Stripped to the frame, we extended the wheelbase by 50mm by extending the swingarm and drivehsaft before refinishing everything in glossy Avus Black glasurit paint. The original would have been finished in a semi gloss, the gloss really helps the bike pop and to the more diligent enthusiast, suggests everything is not what it seems.
The full drivetrain has been rebuilt, starting with a crank out engine rebuild, all the cases have been refinished with a glass beading process before being ultra sonically cleaned. New bearings throughout, a new 1000cc top end from Siebenrock with euro spec high compression pistons, the bike packs a punch. The 5 speed gearbox received the same style rebuild and incorporates a taller 5th gear for better cruising speeds.
The front end has been discreetly upgraded with top of the line suspension from Öhlins, a pair of black telescopic forks wear black rubber gaiters in the style of the ‘80s original. Hand made turn signal mounts were designed for the project to incorporate the original boxy turn signals from the original, a design cue deemed essential by Sabel, the bike’s designer.
A one piece combination gauge is housed in a factory headlight binnacle, incorporating a GPS speedometer and electronic tach, backlit by LEDs. The original bike was offered with an optional tachometer housed in a separate gauge pod bolted to the top triple, an element that always looked awkward and somewhat of an afterthought. A factory R1250GS wheel hub has been vapor blasted and rebuilt before being clad with new Brembo rotors and is attached to the bike via a custom axle. Brakes are factory R1250 calipers from the same R1250GS.
The gas tank is a factory original Paris Dakar steel gas tank finished in Alpine white and adorned with the iconic graphics. Factory solo seat and rack complete the look, complimented by the factory 2 into 1 exhaust system finishing with a chrome muffler and steel exhaust shield. Factory valve covers have been finished with hand made yellow carbon fiber bash guards, inspired by ‘80s rally bikes.
Fueling comes from 38mm SmartCarbs, modern carburetors with a metering rod instead of jets actuated by new versions of the factory hand controls. The factory airbox has been modified to increase airflow with a high performance intake.
Weight of the bike has been reduced drastically with the upgrades. As you can see from the pictures the bike has quite an airy look to it with good visibility through the frame. A 2lb lithium battery is housed under the gas tank and is charged by the new modern charge system. the same charge system provides the bank mounted pickup point for the TwinSpark ignition system, with the second coil pack taking place of the original diode board under the front cover of the engine - the same location used as the pre 1970 bikes.
An LED headlight is mounted in an original style headlight binnacle with a custom aluminum bracket. Factory tuen signals have been mounted on custom aluminum brackets mimicking original placement and are modulated via an M-Wave turn signal relay integrated to the a new factory wiring harness; this creates a gentle pulsating effect of the turn signals, again giving a hint to other road users that all is not what it seems.
The end result is a powerful and reliable analog adventure motorcycle .
