In 2005, the Japanese motorcycle manufacturer launched the Honda CBR600F4i, a sports motorcycle part of the CBR series in its fifth year of production. The bike was unchanged and featured the same visual and technical specifications as the previous models.
The bike debuted in 2001 when the designation was changed from F4 to F4i, which introduced a new Programmed Fuel Injection (PGM-FI) system that allowed for more precise fuel metering and delivery over a wider rpm range, better throttle response, and reduced emissions.
The model was built around a twin-spar aluminum frame and housed a revised suspension that included a 43 mm fully-adjustable cartridge-type fork on the front and a fully-adjustable gas-charged Pro-Link shock absorber on the rear.
For stopping power, the CBR600F4i packed two 296 mm discs with four-piston calipers on the front wheel and one 220 mm disc with a single-piston caliper on the rear wheel for optimum braking performance.
As for the power figures, the 2005 Honda CBR600F4i had its soul brought to life by a 599cc four-stroke four-cylinder liquid-cooled engine that delivered an output power of 110 hp at 12,500 rpm and 65 Nm (48 lb-ft) of torque at 10,500 rpm.
In recognition of Honda's association with MotoGP champion Valentino Rossi and its 500th motorcycle Grand Prix victory, the motorcycle maker made available for Europe and Australia two Rossi Replica versions that were manufactured only in 2001 and 2002.
