The CBR600F4 was produced between 1999 and 2000. It is the last of the CBR600 series of Honda sport bikes to be carbureted. An aluminium twin-spar frame which reduced frame weight was used, and the engine crankcase was designed to share the swingarm pivot. Through a reduction of internal friction and weight, combined with larger valves, shorter stroke and a bigger bore, higher revs were enabled. The spark plug caps had ignition coils built into them. Slightly larger carbs were added and the oil cooler was now located by the oil filter. A new suspension had larger 43 mm (1.7 in) forks and used Fireblade parts. The front brakes were upgraded and the rear wheel increased to 140 mm (5.5 in) with new 3-spoke wheels. The F4 is fitted with Honda's HISS engine immobilizer system.

The weight of the wheels was reduced.[10] The rotor 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.[11]
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.
I'm failing at the Internet tonight. Anyone have the torque specs for front and rear sprockets and the rear axel of a 2002 honda cbr 600 f4i? I've got the front at 40 (ft-lb), rear axel at 69, bolts on sprocket...?
* Goodrich Stainless Braided brake lines (Front) More is better. These give the front brake a stronger feel with less lever travel. Front brake feels better now and gets me on the brakes harder and faster. The twin line is of course better for performance than the 3 line (remember that hydraulic friction is a function of velocity squared), although the 3 line probably looks better.
Many people who commute on a CBR600F motorcycle change the gearing, which is quite easy. A common gearing change is to go down one tooth in front and then up two teeth in the rear (-1/+2). If your chain and sprockets are due for a change, go this way!
New this year, too, are the front brakes, four-piston Nissin jobs with molybdenum/anodic-oxide-coated pistons and Teflon-coated rollback seals. Both of which are aimed at reduced friction, for consistent, fade-free performance under repeated use.
Sure, the new, fuel-injected bike revved much quicker above 7500 rpm, ripping toward redline as though you just punched the hyperspace button. And it showed a bit more speed at the end of the front straight, too-just shy of an indicated 160 mph, if you could read the speedo past the unfortunately placed clutch cable. But the old, carbureted model actually seemed to accelerate harder exiting the pair of second-gear left-handers that lead onto the two long infield sweepers-the most important comers on the track if you subscribe to conventional wisdom, because they lead onto the longest straights. And this despite the fact that the old bike is geared taller than the new one. 2ff7e9595c
