Body weight vs bike weight/size

**lHlonda** · 22-01-2009 02:53 PM

hey all,

i have recently been bike shopping these days (250cc) and i have come across the cbr250r/rr and the new kawa ninja 250r.

both very sexy bikes, after being on both bikes the ninja was way heavier(wasnt allowed to test drive the ninja ><)...

i weigh around 68~70...can anyone briefly explain the maths for this??

maths is obvious all 250cc the more heavier you are the slower it will be..
all i know is

cbr250rr= common, fast, built to last very nimble.
cbr250r= superseded by above, in terms of looks, brakes, frame design.
ninja= looks only.

they all weight roughly the same.. not much heavier or lighter than each other, its just that each have different seating positions and these positions shift the centre of gravity hence making you think its heavier or lighter.
but go with whatever makes you happy..
im about the same weight as you and chose the 250rr.

What math do you want exactly? Power to weight?
Anyway, you are 'ideal weight' for those type of bike.

Go to different dealer to get a test ride of the kawa, then make your choice.

i dont think they let you test ride unless you sign some agreement to buy and very very keen or someshit.
thats what they said to me when i wanted to test a gixer750

remember the center of gravity determines how "heavy" a bike can "feel" both static and while riding.

Oh, so by default the GPX/ZZR is a poor bike then?

the Gpx are a good bike, physically not the prettiest bike but are up there with the 'unbreakable'tag

The GPX/ZZR = new ninja without fairings. They are basically the same bike, although I still wouldnt buy a 'new' bike as a first bike.

zdster is right, i wouldnt get a new bike as a first bike,
as for new ninja is all looks.. to my view i recon so..
sorry im not a fan of them.. at first i was till i rode one.

thanks for the facts guys especially dogcrapau, if ur calculations are right, i must of thought the ninja was heavier cauz the ninja's seating arrangement is far back compared to the cibby.

the maths i was looking for was, if there is actually a limit for weight, eg: if there is a average "body weight" you should be looking at to ride a bike that weighs blah blah blah or vice versa...

There's no weight correlation to bike size or whatever. It usually comes down to rider perception of what they think is a good bike.

The ninja is basically a GPX/ZZR redressed. That engine is a parallel twin. The CBR is an inline 4. What that means is that power delivery between the kwaka and Honda will be different. The kwaka has more torque, a lower redline and a more constant power delivery. The Honda will deliver it in typical honda fashion

go to a different dealer. n ask for a test ride.
dotn go to those stingy ones.

i went to the epping rd honda and all i did was ask if i can test ride. n they had one out the front in 2 mins. n let me go around myself. but then again. might b coz i have full licence~
