I didn’t call you a liar, nor did I say you were wrong, I understand all of Newtons laws, and I know what you are saying, nevertheless you are referring to a almost unnoticeable difference in newer bikes, the internal have already been lightened from the manufacturer. I know about rotating mass but everything you are referring to in a liter bike isn’t going to make that big of a difference. Agreed the rotating mass of the engine may be slightly more, nontheless that engine creates more hp and tq. The geometry of the bike yet again makes this almost unnoticeable. Agreed that the new 600rr handle GREAT I am not denying that fact nor am I denying you to be right, however on the efficient bikes of today it isn’t a great difference from 600s to 1000s as far as rotating mass is concerned. Yet again I am agreeing with Newtons laws to argue that would be pointless. But noticing the difference in a bike with the same frame, and the same size tires and rims with the same geometry one with a 1000cc one with a 600cc engine, I would say is nearly impossible. I agree to disagree while agreeing =D.

 

Would definitely not start with a 1000. A 600 is more then enough power. When I started on my 600 I thought it was the fastest thing in the world. I then got used to it after A LOT OF riding and got a 1000. I'll tell you this, once you go 1000 you never go back. 600 will feel like scooters after being on a 1000 and push its potential to the max. But start on a 600 and master that first.

 

I've not met anyone that has push either too their max potential lol


Watched the few that come close on TV tho

 

I think I'll eventually get a liter bike or bigger because I want more low end torque for around town, and relaxed low-rev cruising on the highway. Gearing down a 600 would give me the first, but not the second

 

ask a thousand people, get a thousand opinions...

600:
pros - easier throttle control, lower tco (fuel mileage, insurance, ...)
cons - less power, more shifting around town, higher cruising revs on the highway.

1000:
pros - permanent grin from power on demand.
cons - mostly tco.

i rode a 600 (f4i) for several years and it was a great daily ride with forgiving handling. after a while, the power thing becomes more apparent, esp if you're more into 'touring'. i can honestly say my 1000 feels more comfortable, flickable and lighter than the f4i ever did. requires much more focused driving tho. the difference in model years and technology is what i attribute most of those aspects to; so model year factors into the evaluation. same model year 600 vs 1000, i'd say the only real advantage to the 1000 is in a straight line.

personally, i'd recommend a 600 for a few years. you won't be (too) disappointed. 8D

 

I rode dirtbikes since i was 10years old, at 21 i got my first sportbike a 00 f4, put the goodies on it put 20,000miles on it then i bout a 07cbr1000rr 2years later.

Going from the 600 to a 1000 is nite and day. The response, the acceleration, its so much more intense then a 600. I still having went full throttle in 1st gear after 9000miles on it. 1000cc are definately not for beginners of any nature. I dont care if you rode one, that doesnt mean you can handle it on a day to day bases and it takes alot of respect the power it has compared to a 600.

But i agree with previous replys, 600 is great for a track bike because you can get on it hard out of a corner, a 1000cc bike takes more finesse out of the corner because it has enough torque to slide the *** out if you get on it too hard. The 600 and 1000cc weigh close to the same. My 600 felt just as lite as the 1000cc.

go with a 600cc and stick with it for a few years, if your still alive then get a 1000cc

 

I do have to say one thing about a 1000, I have a friend who is 6'6" and weighs in at 280 pounds. His first bike was a Yamaha R1, a 1000. Because he is so big, he got a 1000 to pull his fat *ss around. And he has no issues. But you being 120 lbs, you have to able to hold up a bike, and pick it up off the ground if it ever falls over. My friend was the exception. And he now rides a Harley, and his R1 sits on stands.

 

unfortunately thats a cop out too. Size hasnt got shyt to do with knowing how too ride. A 600 would pull his fat *** just fine. I ride 2up alot on my 600 and still pass 1k's in the mtns with single riders.

 

I've had an 06 f4i as the first bike, then i moved to 08 1000RR.

New bike feels a lot more comfortable, a lot more stable(balance wise), and of course it just looks damn better. I don't push my bikes as much as other people do, i just love the power and the acceleration it has. The looks are also a plus.

I would take 1000rr over f4i any time, but definately not as the first bike though. F4i is very forgiving and really easy to learn how to ride.

Whatever bike you get you can *** yourself up if you are not smart. Just realise that we, the riders, are the limiting factor in bikes performance.

Good luck

 

I myself just bought an 02 cbr 600 f4i. this is after ie owned a 98 900, an 86 shadow 500, a harley electra glide, and a 78 yamaha xs650. I'm a gear head that likes to fix em up then get bored and want something different. but the 98 cbr had the rrr supercharger and nos on it. it definately had more power than this new 600 but this new one has still jumped up and suprised me a few times. I also think the 600 is more fun myself seeing i dont go to the track it is easier to handle, i can crack the throttle and not worry about that 8 sec bull ride, and its still fast as hell. but what i see the most from all my guys(army) buying a NEW bike is not realizing there is soap on the tires from the dealer and laying them down right in the dealer parking lot. 1k sport, 600 sport, big and small cruisers too. whatever you decide to get just respect that you are stradling and engine and take the time to get to know it!
