Nothing grows data like expertise. So the sole system to determine the finest technique to compose a continent-crossing bike, is to in actuality abominable a continent—then peep what works, and what doesn’t.
Benefit in 2016, Matias Corea rode his 1985 BMW R80G/S Paris Dakar from Brooklyn your complete system to Ushuaia, in Argentina. Now he’s bought one other outing deliberate: a 22,000-mile drag from his native Barcelona to Cape Town in South Africa. So he’s taken the lessons from his first outing, and built his imaginative and prescient of the final drag airhead.
“After 20,000 miles in 168 days, you bring together a clear idea of what the bike is good of and its limitations,” he says. “This compose is in accordance with every little thing I learned on that outing. By the discontinue, I had mapped out every little thing I desired to alter to provide you with the option to tour the sector with an airhead.”
With too unheard of reverence to regulate his long-established G/S, Matias began with its conclude cousin: the 1983 BMW R80ST. The Brooklyn-basically basically based mostly dressmaker’s foremost level of curiosity became on making inspiring upgrades, and building a authentic and simple-to-work-on bike.
“Every ingredient on the bike became vetted on the sphere of how straightforward it would possibly perhaps well maybe be to restore or replace wherever in Africa,” he says. “That mindset modified my perspective on what is a groovy various and what’s a valid kind various.”
Matias went deep in his pursuit for perfection, starting with an engine ability bump to 1,001 cc. The heads went off to Moorespeed in Northampton, UK, to be ported, gasoline-flowed, and modified to bustle oversized inlet and utilize valves. Matias then rebuilt the motor with excessive compression Moorespeed pistons and an asymmetrical racing camshaft.
The crankshaft, rods, pistons, and flywheel assembly were all dynamically balanced, to maximise efficiency and toughen throttle response. Matias furthermore installed 40 mm Bing carbs, then ditched the airbox and modified the consumption to retain an originate rally filter. The utilize is from the normal BMW consultants Siebenrock.
“This engine now pulls 72 hp on the rear wheel and feels unheard of between 5500 and 7000rpm,” says Matias. (A stock R80ST makes about 50 hp on the crank.)
Bettering the BMW’s handling called for not only suspension upgrades, but some chassis work too. Matias turned to grasp welder Esteban Pasquale, who welded 14 reinforcement plates into the frame. The subframe became pivoted forward, and furthermore bolstered with two diagonal supports and a built-in rear rack.
The entrance discontinue became upgraded with a location of WP Suspension originate chamber forks, with a whopping 250 mm of commute. A 21” Excel rim became laced to a Talon hub with heavy-accountability stainless-steel spokes, and matched to a single four-piston Brembo brake caliper. “I went with a single due to a twin entrance disc makes the wheel considerably heavier and it system twice as many substances to peril about,” explains Matias.
Out succor, the boxer’s shaft pressure swingarm became stretched by 100 mm, and curved up to a custom-built Wilbers shock. The closing pressure became overhauled with fresh bearings, and the rear drum brake became flipped vertically to guard the appealing fragment from rocks. The OEM rear wheel hub became then drilled, in assert that it would possibly perhaps well maybe be laced to an 18” Excel rim.
Matias fitted Mitas E-07 twin sport tires at both ends, utilizing the fresh rear wheel’s offset to squeeze in a 130-wide rear. The heart stand needed to be modified to accommodate the taller suspension, and now has a foot lever to serve in lifting the bike.
For the fuel tank, Matias went straight to the crew that built the BMW Dakar bikes within the 80s—HPN. He began with a 11.3 gallon nylon unit, and made determined that a clear strip became left on the succor of when it became painted, to operate as an analog fuel gauge.
“If you happen to hotfoot via extra remoted areas,” he explains, “low-high quality fuel is a given. That can map ‘pinging’ which is abominable for the motor. To circumvent the matter, the bike has a twin curve ignition system that can even be switched from the hotfoot to retard the timing.”
Up within the cockpit, Matias match the distinctive R80ST dials to an Acerbis fairing, and added a twin-port marine-grade USB hub, a hazard light switch, and the ignition curve switch. He furthermore installed Magura handlebars on taller risers, with Acerbis handguards and BMW mirrors.
Out succor is a modified HPN rear fender, geared up with the BMW’s long-established taillight and flip signals. It’s flanked by a pair of sturdy Hepco Becker exhausting cases. Other upgrades consist of a Shorai Lithium-ion battery, reduced foot pegs and a pair of ultra-vivid Baja Create S1 LED fog lights, mounted to the entrance crash bars.
The magnificent minimalist livery became completed by the same man that paints Walt Siegl’s bikes: Robbie Nigl at Peach Pit Motorcycle Painting. The ‘M’ motif on the tank refers to ‘Story Motor’—Matias’ fresh bike ticket.
“This is Story 001,” he says, “and even though it’s a completely accomplished bike it stands as a prototype in my solutions.”
“After the Africa expertise I could proceed to abolish changes and toughen the idea that; there’s consistently one thing fresh to steal a search at. I want to provide only my easiest work for other drag riders across the sector.”
This ‘G/S’ is a flawless mix of traditional model, usability and efficiency. And the truth that it’s poised to abominable a literal continent later this year, makes it your complete extra irresistible.
