Revival Cycles of Austin, Texas has unveiled a custom bike around the prototype of a new type of BMW Motorrad Big Boxer engine, at the exclusive Revival Party on the eve of the annually held Handbuilt Show in Austin/Texas.
“The Revival Birdcage turned out great and really showcases BMW’s Big Boxer perfectly”, says Timo Resch, Vice President Sales and Marketing BMW Motorrad. “Following the ‘Departed’ from Japan’s Custom Works Zon, this is the second custom bike built around the prototype.” BMW Motorrad will present a series production motorcycle with the Big Boxer for the Cruiser segment in the course of 2020.

The frame of the Revival Birdcage is made of titanium and was developed by Revival Cycles itself. “This was our first time to build a frame with titanium, that alone was already a significant challenge”, says Alan Stulberg. “Regardless, the frame came together very well in the end and we are very pleased with the result as it accomplished the goal of being nearly transparent. We wanted to focus attention on the engine and that is precisely what we achieved with this completely unique frame we designed. You can easily view the engine and the drivetrain from all angles.” In addition, almost every single other part on the bike such as handlebars, footrests, shift lever, seat and unique carbon suspension components were all individually crafted.
Alan Stulberg’s team was inspired by Ernst Hennes’ record-setting machines from the late 1920s and early 1930s. It took around six months to develop the motorcycle. “We had already dreamed about this bike for years and in December 2018 we received the engine and could finally get to work”, says Alan Stulberg. “I have always been a fan of the boxer engine, but the pure physical size and aesthetic appeal of this prototype really inspired us.” The bike was completed in time for the Handbuilt Show in a period of nearly five months.

There had already been a lot of speculation about the large-capacity prototype engine on location. Both the exterior geometry as well as the visible elements such as the push rods running in chrome-plated protection ducts are reminiscent of the BMW Motorrad Boxer engines that were built in the 1960s, but the cubic capacity is now much larger now and modern air-oil cooling is used.
An earlier custom bike by Custom Works Zon, based on the same prototype, won the Best of Show Motorcycle award at the Hot Rod Custom Show in 2018.
