Kawasaki’s iconic green and black colorway is about as famous as the moto brand itself — so when we see a custom motorcycle build that departs from the original scheme, it puts us on edge. Thankfully, Toronto’s MOTOBRIX cycle studio is as talented as they come, easing our worries by retrofitting a beautiful 1974 S3 that they’ve come to know as “El Citron.”
Brian Kates’ 1974 S3 is certainly a departure from the original bike — but, like many of MOTOBRIX’s custom projects, the transformation from a drab, overbearing donor into a beauteous beast is all part of a good day’s work. After acquiring the 400cc triple two stroke from a friend, Kates opted for an entire front end swap, courtesy of a GSX-R600. A Cognito Moto steering stem, custom fabricated front light, and orbital mount gives the S3’s leading end a more aggressive look. At the rear, a Suzuki Bandit 600 swingarm and GSX-R1000 monoshock bring the bike into modernity, alongside a deconstructed and rebored engine, rebuilt oil pump, fabricated Higgspeed expansion chamber exhaust, and a sand bent, handmade subframe. A handsome yellow, black, and polished metal color scheme was implemented courtesy of Black Widow Custom Paint — rounding out Kates’ ambitious four-year build.
