Yamaha FZR400S Motorcycle - Street (1988-1990)

The Yamaha FZR400S, a revered sportbike from 1988 to 1990, was powered by a consistent 399cc liquid-cooled, four-stroke, inline-four engine. This DOHC, four-valve-per-cylinder unit was part of Yamaha's "Genesis" family, known for its forward-inclined cylinders optimizing intake. While engine displacement remained constant, the FZR400S saw notable updates. The primary model was often referred to as the FZR400 or FZR400R. A significant mid-cycle evolution occurred with the 1990 model, which introduced upgraded braking featuring larger four-piston front discs and an aluminum Deltabox swingarm, a substantial improvement over the earlier steel unit. Around this time, a more performance-oriented variant, the FZR400RR SP, also emerged, offering enhanced capabilities. These changes reflect Yamaha's continuous refinement of the FZR400 platform during this period. FAQ:
