From Brittany to Milwaukee: French engineer Chloe Lerin has followed an unusual career path. Rebuked by KTM and BMW, she elected to stay in America after school, working for Cummins diesel and John Deere before landing at her current gig developing powertrains for Harley-Davidson. A racing enthusiast, Lerin also works with Harley’s entry in King of the Baggers, the madcap racing series where Indian and Harley cruisers are modified to go at ungodly speeds. Lerin—never one to sit idle—is also a data engineer for a Suzuki-backed road-racing team in MotoAmerica.
