Two Motorcycle Engines Create a 15,000 RPM Trombone Duet
A YouTuber known as Maisteer rigs two Suzuki GSX-R motorcycle engines together with a custom exhaust and drive setup to perform a trombone duet at up to 15,000 RPM, using scrap parts and sponsors’ CNC/3D-printed components. The project is presented as playful art-for-art’s-sake tinkering, complete with flames and a lengthy, entertaining build video.
