The front end was upgraded with a set of WP Suspension open-chamber forks, with a whopping 250 millimeters of travel. A 21-inch Excel rim was laced to a Talon hub with heavy-duty stainless steel spokes and matched to a single four-piston Brembo brake caliper. “I went with a single because a dual front disc makes the wheel considerably heavier, and it means twice as many components to worry about,” explains Corea.
In the rear, the boxer’s shaft drive swingarm was stretched by 100 millimeters and hooked up to a custom-built Wilbers shock. The final drive was overhauled with new bearings, and the rear drum brake was flipped vertically to protect the moving part from rocks. The OEM rear wheel hub was then drilled so that it could be laced to an 18-inch Excel rim.
Corea fitted Mitas E-07 dual sport tires at both ends, utilizing the new rear wheel’s offset to squeeze in a 130-wide rear. The center stand had to be modified to accommodate the taller suspension, and now has a foot lever to aid in lifting the bike.
For the fuel tank, Corea went straight to the crew that built the BMW Dakar bikes in the ’80s: HPN. He started with a 11.3-gallon nylon unit, and made sure that a clear strip was left behind when it was painted, to function as an analog fuel gauge.
“When you ride through more isolated areas,” he explains, “low-quality fuel is a given. That can create ‘pinging,’ which is dangerous for the motor. To circumvent the issue, the bike has a dual curve ignition system that can be switched from the dash to retard the timing.”
