well im looking at the specs of both 900rr and the f3, they are not that far apart in design. the f3 is a bit smaller than the 900rrin size but weighs 2 pounds more stock. looking at both bikes, they are almost aerodynamically even... even tho the 900rr is bulkier, it has vent holes to let air pass by... so if anything, with the 900rr wheel behind, the f3 would just handle like a 900rr which is not that bad... my bike handles pretty well i must say

 

Not true. The f3 has different geometry than the 900rr and the wider rim will affect how a tire is shaped when inflated and affect the ride. For a wider tire, say a 180, you may have a larger contact patch but turn-in will be slower.

 

from every person that i talk to, they say if u want power, go a 900 or 1kcc bike, but 600's would always handle better. I havent been on a 900rr but i have been on a 954 before and there definately is a difference in handling between them and my 600. 600s falls into turns a lot faster than the 954. and plus 600's can rev closer to their peak power in turns as opposed to the larger motor bikes. i can only assume that the 900rr has just the same ground-to-wheel contact dynamic as the 954 there for if i have the same size rims front and back of a 900rr/919/929/954, i think its safe to say that my bike would handle like 900rr/919/929/954.

i understand that the f2/3 has different geometry but if the tire size is equally proportional to the rim as a 160 on a 4.5 rim is almsot as similar as a 180 on a 5.5 rim. and plus 160 tires fall into turns easier, less of a distance to travel around the tire in thee rear

 

installed 160 60 in rear and 120 60 in front and wow it made a huge difference.

 

I take it my post was deleted.

Basically nick, Your a YOu know jack ****, and it is showing. Stop now.
Jst please stop. You obviously do not know anything about what your talking about and pulling stop out your butt. You need to sit down, open up a geometry book. Then when your done, Open up a book on chassis design and handling. Becouse what your saying well. Belongs on the CBR Short Bus.

 

160 60 rear 120 60 front is the only way to go!!!!!!

 

Dont be a douche man... i have my degree in engineering. I must admit i am fairly new to bikes but give me both bikes under the circumstances that i stated and i will measure it out and prove it... i dont know if you read that i have a 900rr rear wheel currently on my bike and front wheel profile of both bikes are a 120 so i am basing the information comparable to MY bike, not anybody elses.

 

take it easy guys!!!

 

appologies... ill get back on topic... hows the tire holdin out

 

Yes
I forgot, you have the only Cbr600f3 that has the same steering head geometry, fork length, 16 inch front wheel, ( yes I know they eventrually changed to a 17inch front) But they also changed the whole bike for that. YOu must also have they same chassis stiffness. What a unique bike.


Engineering degree in what? Model airplains. Becouse It isnt in motorcycles. So Im tring to be nice, but seriously you dont know what your talking about so please stop. YOur going to fill others with that dribble.
