Hyosung GV125S Bobber Aquila Specifications – Pictures – Manual
Hyosung GV125-S Aquila Bobber (2019-Present) – The only 125 “Bobber” styled EFI Liquid cooled V-twin on the market!
Since the start of the 2000s, the Aquila 125 bikes went through body & ancillaries changes whilst retaining the same frame & V-twin SOHC engine.
Almost 20 years later we see whole design changes, gadgets, a chassis update & an engine that’s finally liquid cooled!
