i have heard the same thing. my pal just bought a 2000f4, it came with an Elka shock and the Pre owner raised the back end on it to. not sure how much, 3/8" i think. i'm looking forward to triing it out against my stock geometry for comparison. i'm adding racetec internals up front soon.
do u track your bike? our other riding partner just picked up an 05 cbr6rr.
i have sent u a new PM.

 

I have about 5mm of shims for my rear shock which equals about 15mm in ride height. I also have my front end dumped down another 5-10mm. It still doesn't turn in quite as quickly as I want but its much much better then stock.

 

Sort of right in my opinion, but I think for track it's a big advantage to do the swap.

The newer forks can be adjusted much better than the standard F4i with better internals. Further more will the newer forks allow you to run bigger brake disc's, which means harder braking less heat. Last thing is the newer forks and front wheels is much lighter than the F4i.

 

When the F4i was winning championships as hondas flagship 600 the 900 series [900/929/954rr] had inverted forks as did previous v4 sportbikes from honda yet honda still ran standerd forks on the race bike. If they made such a big difference in the f4i's handling then they would have utilized them in the race series.

 

Correct me if I'm wrong, I can't remember any championship win's. It was a good bike and it took some podiums, but that's all I think.

Anyway, I'm pretty sure that if you took a top racer and put him on a standard F4i Vs another top racer on a F4i with 08 600RR forks the second will win. And one of the reasons the RR is a much better bike is not power, it's much better suspension and chassis.

Of course for most of us the F4i is more than capable as standard, but we can not do what a pro racer can. We can not adapt to the bike's faults and behaviors as they can. So if you want to go faster on track, with out riding on the limit, these upgrades are a big plus.

An example from my own life. I race with Andy Carlile. He has the official lap record on motorcycle around Nürburgring in Germany. He raced my F4 around Dijon in 1.34,5. This is with bt016 tires and a engine that was purely setup. I could not get along with the tires (bt016 slide a lot in the heat) and the bad throttle response so my fastest was around 1.40. Two weeks later I was again on the same track with engine setup and bt003's. I ran a 1.36,5. Just trying to say, if you are not a pro a good setup bike make's one hell of a difference.

 

AWESOME, exactly the info I need!


True, but you have to remember that those were the very first years that the top of the line SS had inverted forks; it is also true that tech starts from the top of the line, and it trickles down.

If non inverted forks and non radial calipers where better, then all modern sportbikes would be using them.

 

the f4i won the 2002 world supersport championship
