carriers moved out closer to the brake calipers to reduce weight and to improve rigidity. But stopping power still was not on par with other bikes in the class. There is additional bracing on the steering head for more response, better feedback and feel from the front end. The suspension has also been tweaked with less high-speed damping and a little more low-speed damping with the shock and fork being more street-bias. Additional engine changes include a lighter camshaft sprocket and increased valve spring pressure (two springs per intake valve) which allow for higher revving. There are new piston rings that slide with less friction and increased internal engine oil flow. Redline is now 14,200 rpm, 700 rpm higher than the previous year's F4. To increase the bike's pulling capabilities at high speeds, the fifth and sixth gears have been shortened slightly and the rear sprocket was enlarged from 45 teeth to 46, also adding one clutch plate for greater durability to now making 8. The oiling holes in the camshafts have been enlarged by (to ) and piston ring friction has been decreased to aid cooling at the higher rev ceiling. Spring pressures on the intake and exhaust valves have been increased to avoid valve float. Also, there are now two valve springs (inner and outer) on the intake side instead of the single item that resides on the exhaust side. The F4i's new bodywork carries a more racy look and provides a 3% reduction in drag. It also houses a new dual headlight front cowl design which uses 40% brighter H7 bulbs compared to the old H4 bulbs. The headlights are dual multi-reflector units covered by a one-piece flexiglass lens. The turn stalks are shorter and the mirrors are now positioned higher and closer to the rider. The elimination of carburetors allowed for a slightly larger air box and a larger fuel tank. And a fuel consumption of . In 2001 and 2002, in recognition of Honda's association with MotoGP champion Valentino Rossi and its 500th motorcycle Grand Prix victory, the CBR600F4i was also released in Europe and Australia (2001 & 2002 only) in two "Rossi Replica" versions. CBR600F (2011–2013) In 2011, Honda released the new CBR600F model built in Italy for the European markets that was not released in America. It continues the legacy of the CBR-F line.
