This leads me to another question; does your body weight play a part in deciding on the displacement ofa bike? I would assume that if you had two people of equal skills, but one weights 150 and the other ways 250, the bigger person could handle a higher displacement better. Am I wrong? I mean put a 100 pound person on a 250r and it would feel like a Busa

 

They are all rockets and plenty fast. I remmeber reading some guy rode two up (so around 400 lbs.) and he was amazed how quick it was. The 1000 is faster no matter what size you are.

 

f4i all the way im 235 and it moves me great

 

If your comfortable on the Nija you should do fine on a bigger bike, I would not buy a Katana, it's old school, air cooled heavy brakes suck, etc.. there's just better bikes out there,, we own a 05 F4I and a 06SV650S, wife owns th F4I, daughter rides the SV, persoannly I prefer teh SV, it's low end Torque makes it fun and easy to ride, much harder to stall, the F4I is fun when your riding it above 9K RPM's you got to ring it's neck to get it to work, but once up ther in those RPM's it will stomp teh SV, but for an easy fun bike to ride, I'd go with the SV. it's much more enjoyable to ride.

 

The fact that you even made this post means you are cautious and will have no problems with a 600 cc bike. The F4i is a great bike. I started on one and had no problem learning on it. Just get good gear and wear it!

 

just throwing my 2 cents in.

If you had mentioned that this was your first bike I would have said no. However you have mentioned you have a season on a 250. That's great bro!

In no way is the f4i a begginer or first bike, after some good riding though on a good starter sportbike like you have done I think you will enjoy it and if you like it get it. I moved up to it after a season on a Ninja 500 (still wish I had that bike).

The 600cc supersports are flat out horrible starting bikes for new riders. Even the F4i falls into that category as much as it is not serious race ready but it has all the technology and power of a previous supersport and was easily one of the top track bikes several years ago.

If you are thinking of an f4i that's great, my personal reasons I went for it was, comfort, Honda reliability (the bike engine is bulletproof), price/insurance favorability, it's a bike that isn't made any more and it's different.

Best of luck getting one they aren't going to be made anymore. Let us know what you do.

 

Going back to the weight/power issue - i regularly ride double up (me plus g/f probably around 310ish) and we have no problem zipping through twisties and hitting triple digits on the highway (very rarely, and when no cars are around of course to be as safe as possible at those speeds) - so don't worry, it will be more than enough for you to pucker your a-hole :-p

 

my first bike was an f4i and i was great wasnt to fast. i havent even riden a dirt bike. the throttle is as aggressive as the rr. its a great beginner bike but i crashed so so can you. be careful

 

purchased my first bike at the start of this season, an 01 f4i, found it incredibly easy to learn and ride comfortably, its a leap that one can make easily if you are confident and dont push yourself past your ability, in closing go with the f4i.

 

A friend of a friend went from a 250 to a literbike and was fine. The key is that you got previous experience. You can basically get anything you want as your second bike. One caveat, though. Use your 250 like you will use the next bike. Generally the most dangerous thing about riding is performance cornering on public roads. If you are going to get a 600 and take it to the twisties and do 15 mph turns at 40 mph, then make sure you can do that on the 250 before trying to do it on something else. That was just an example. The point behind it is, don't just commute around with the 250 doing the speed limit in 35 mph zones and then go get a 600 and think your previous experience has made you able to take 35 mph turns at 120 mph. I mean it's OK if you don't, but just don't consider yourself experienced. I went from a 750cc cruiser to a 600. I counted the 11,200 miles I rode on that cruiser for absolutely nothing toward my overall experience because I did absolutely no performance riding on it. The guy I mentioned that went from a 250 to a literbike rode the hell out of that 250 before he upgraded.
