The R80 G / S from Matias got a good 30,000 kilometers on a tour from Brooklyn to Ushuaia in Argentina. Now there are another 35,000 from Barcelona to Cape Town.

But Matias has too much respect for his G / S for the new trip. So he completely rebuilds a 1983 ST.

Matias has no fewer than 14 reinforcement plates welded into the main frame, and two additional diagonal struts reinforce the rear frame, which has been moved forward slightly with a new lashing frame. In this way, the frame can now also tolerate real spring elements with a good commute.

At the front, Matias uses a WP fork with 250 millimeters of travel, with a light single-disc brake system, floating Brembo saddle and a 21-inch Talon rim.

When it comes to the tank, Matias makes no compromises. He orders one of the Dakar nylon tanks from HPN with a capacity of 43 liters and should he ever fill up with bad fuel, two ignition curves that can be switched in the cockpit help keep the engine from knocking.

The original oil cooler in conjunction with an extension ring for the oil pan and an improved thermostat keeps the temperature in check.

The rear brake drum is rotated 180 degrees to protect the deflection from falling rocks. The original hub is reworked to accommodate an 18-inch Excel rim with a 130 tire.

As an upgrade for the 797.5 cubic centimeter boxer, Matias chose a big-bore kit with high-compression Moorespeed pistons, sharp camshafts and revised cylinder heads. Together with a Siebenrock exhaust system, the now 1,001 cubic engine produces a good 72 hp on the rear wheel.

The cockpit consists of the original round instruments of the R80 ST in the new holder. This is also where the switch for switching the ignition curves to bad fuel is located.

At the rear, the swing arm and the cardan shaft must first be lengthened through the long fork. The final drive is 100 millimeters longer and creates space for a Wilbers shock absorber.

Original BMW ST gets fit for Cape Town

The R80 G / S from Matias got a good 30,000 kilometers on a tour from Brooklyn to Ushuaia in Argentina. Now another 35,000 are on a tour from Barcelona to Cape Town – on a converted R 80 ST.

Matias knows his 1985 R 80 G / S inside and out. He drives his BMW over 30,000 kilometers from Brooklyn to the southernmost point of the American continent, to Ushuaia in Argentina. He and a friend are on the road for seven months. Now Matias is planning a new trip. From his native city of Barcelona to Cape Town. But too much respect for his G / S made him grab a 1983 ST and completely rebuilt it.

More displacement and performance

After 30,000 kilometers + X, an overhaul of the 797.5 cubic centimeter boxer is only fair. Matias chooses a big-bore kit with high-compression Moorespeed pistons, sharp camshafts and revised cylinder heads. Together with a Siebenrock exhaust system, the now 1,001 cubic engine produces a good 72 hp on the rear wheel.

Their 797.5 cubic centimeter boxers are made fit for the big tour in advance. Matias chooses a big-bore kit with high-compression Moorespeed pistons, sharp camshafts and revised cylinder heads. Together with a Siebenrock exhaust system, the now 1,001 cubic engine produces a good 72 hp on the rear wheel, where the original boxer only brings 50 hp to the clutch. Everything finely balanced and fitted with 40 mm Bing carburetors with an open filter. The original oil cooler in conjunction with an extension ring for the oil pan and an improved thermostat keeps the temperature in check.

Reinforced frame, extended chassis

43 liter tank, two ignition curves

Conclusion

Probably Matias could have bought a brand new super enduro with the budget and probably still had some money left over. But the emotional connection to the old carburetor boxer and its impressive resistance to all external influences cannot be argued with modern technology. Good this way. And have a good trip.
