Custom of the Week: BMW R80 G/S ‘Africa Shox’

Modern Dakar bikes are lightweight, sophisticated off-roaders, with a maximum capacity of 450cc.

But the early days of the rally were dominated by mammoth desert racers—like the mighty BMW R80G/S, which racked up four wins in the 80s.

This immaculate 1982 model is a restomod owned by Mark Johnston, and it’s a spectacular homage to the Dakar-winning days of the Gelände/Straße. Remarkably, it’s only Mark’s second build: Bike Exif featured his first last year, and when we teased a shot of this R80G/S alongside, readers insisted on seeing more.

Mark lives in the northern suburbs of Cape Town, South Africa, but bought the bike blind from a guy upcountry in Pretoria.

“I wasn’t too concerned about the overall condition, as most of it was going to be replaced anyway,” he says. “But the bike turned out to be OK in the end.”

‘OK’ didn’t stop Mark from ripping out the G/S’s motor and shipping it to Volker Schroer in Port Elizabeth. Volker rebuilt it from the ground up, bumping the capacity to 1,000 cc with a big bore kit from Siebenrock. The work included gas flowing the heads, and installing valves suitable for unleaded petrol. The exhaust silencer is from Akrapovič, but the header is custom, courtesy of Scorch Design.

Back home, Mark began transforming the classic Beemer’s chassis. He started with a set of 48mm upside-down WP Suspension forks up front, liberated from a KTM 525 EXC. The forks were also fully rebuilt, with new stanchions and stiffer springs.

They’re hooked up to the bike via a set of custom triples, made by Mark’s go-to guy for machining: Ian Ketterer at BlackSilver Customs. The front wheel is an all-new custom setup, and the front brake caliper was rebuilt and connected to a new master cylinder.

Out back, the swingarm was lengthened by almost two inches, and an offset added so that a 140-section tire could be squeezed in. The rear shock’s a one-off too, built by local suspension guru Martin Paetzold at MP Custom Valve.

The subframe’s another custom piece, built for one and with a non-removable luggage rack. Look further down, and you’ll notice that the subframe support struts also include tiny hooks for securing luggage straps.

For the seat, Mark used the original two-up pan, but cut it shorter and reshaped the back with fiberglass to accommodate the rear fender. He then re-shaped the foam, added a gel pad and sent the seat to Alfin Upholsterers for a fresh cover.

Just in front of it is an HPN rally tank, imported from Germany and painted in a variant of the original Paris Dakar race livery.

The headlight mask is an OEM BMW item (from the original ‘Paris Dakar’ edition of the R80G/S), but revised to work with quick-release straps. Off-road style fenders conclude the bodywork at each end.

“The bike rides like a dream,” he reports. “With all the changes, you wouldn’t think you’re riding a 37-year-old bike. I put on 4,000 km in no time riding the South African countryside.”
