I bought a 06 F4i last spring. I really like the bike but the salesman never said anything about rider weight etc. I read on the F4i forum that a few heavier guys like me (225 lbs) have put heavier springs in the front and rear to compensate for their weight. If I upgraded to an 1000RR, would I have to do the same suspension modifications? I would assume that if I went with an 600RR, the suspension would need upgraded also?

Thanks

well i was about 200lbs when i had a f4i a few years ago, i didnt have any problems with the front forks whatsoever.
these days i am up to 230 and the new 2006 cbr 1000rr also does not give me any problems.

however, this is just with me alone. when i put my wife on the back of either bike i need to be real careful.

i think you will probley do jsut fine with you stock setup. unless your doing time on the track that is.

lastly, get a 1000rr man, its a way nicer machine.

I weigh 225 and have the 06 1krr; factory suspension, no problems; I can think of only two times I would consider upgrading, 1) if it were really going to do some heavy track time and 2) if all of sudden I had a pile of money. I just looked into to doing a full ohlins setup and pvm wheels, 5k is a chunk of change, and I have yet to max my suspenion out yet, so i am thinking its fine for now...

 

I am A LOT heavier than you guys and my 06 1000RR has not had an trouble. I wouldn't worry about it, 225 is light!

 

All bikes can benefit from correctly adjusting the suspension to best fit you. There is a certain amount of adjustment you can make to the stock spring to accomodate heavier riders. But generally speaking, you shouldn't have any problems from the factory settings.

 

The avg street rider won't find any flaws with OEM suspension.
The fork springs are WEAK, but unless your on the track it doesn't matter.

Example: The 2004/2005 fork springs were setup for a TRACK weight rider of about 155lbs.
Obviously, most 200lbs riders "had no problems" on the street.

Yes, there is an optimal setup for your weight, but unless you are racing it doesn't matter,
the stock stuff is "good enough".

If all you do is drive up and down Main Street at night, trying to look cool for the girls, and maybe pulling
a few short 1st gear wheelies to impress all your GSXR buddies, then the stock springs are fine even
for a 350lbs rider.

If you are 250+ and race, you'll be on your ***.
