think the easiest way will be skimming some foam from the seat

get the seat, take leather stuff off it

cut some foam away, re-leather it

i dont think the suspensions adjustable so it would be a new rew coil if you wanted that ajusting

Are you a midget? the cbr is fairly low as it is lol.

As said, you can remove some foam from the seat to lose a little bit of height, if this isn't enough though you'll have to turn your attention to the rear shock. It's not adjustable, but wether there are multiple holes on the mounting bracket for the top of the shock so these holes make the shock sit at different angles, adjusting ride height i am not sure, doubt it.
You may end up having to buy an adjustable aftermarket shock.
Or possibly a spring for a lighter weight rider, i guess that might cause the rear end to sag slightly.

How short are you? The CBR is already a very small bike, most peoples problems are just a lack of confidence, you don't need to be tall (or even able to touch the floor to some extent) to ride bikes.

as long as you can put your tip toes on the floor on on side then you'll be fine.

you must have an inside leg of like 12 inches to not be able to cope on a cbr 125!
aseanmoto sell an adjustable shock which could work however it would adjust the feel of the bike.

Thanks for the advice lads, it's my Daughters bike and she is

a) Short
b) Very new to biking so she may get to be OK with more experience.

Thanks

How short? I'm 5'6" and have not found a bike I cant ride yet. You never need to touch the floor once you are moving and only ever need 1 foot on the floor when stopped so as long as she can touch the floor with 1 foot without struggling the problem is just psychological.

I know a girl who is obsessed with lowering her bikes, she has an SV650 with lowered suspension and a cut down seat and still drops it really quite regularly because she has no confidence and believes she is too short, in reality she is not much shorter than me.

If she is seriously small then it might be a problem but apart from that you might end up doing more harm than good by reinforcing the lack of confidence. She would also be very limited too her next bike if she wanted to move up as there very few bikes as small as the CBR about.

Hi, I'm 5'2 and the cbr125 was the best bike I tried before deciding on one. Yes the ybr and cg also have a slightly lower seat height but they aren't as appealing as the cbr (imo)
Take her to some dealers and let her sit on bikes and feel the weight of them and the riding positions.
Best of luck to her I hope she finds a bike she likes and gets out on the road soon.

I have been addressing the very same need recently and this company: http://www.performanceparts-ltd.com/ have been well on top of their custmer service and got back to me almost immediately. I am buying a replacement spring from them to fit onto the stock shock, and the replacement spring is 80-odd pounds and VAT and postage. Much cheaper than a new shock (£300 upwards), and the claimed amount of reduction of seat height is by 30mm.

Aside from what colour the spring is (forgot to ask), I am curious to know if anyone here had ever "undone" a CBR125 shock???

There is no easy way of doing it apart from adding material to the seat.

ahh man i wanted to highten the rear end to give it more of pointed down look and i find that higher is more comfortable aswell.

ive seen kits that allow yyou to lower the bike by like 30mm using springs and kits to highten the bike using aftermarket shocks but at like 366 for a complete shock is too expensive but for the guy that wants to lower the bike, there is a 30 mm lowering springs that cost like 70 pound

lowering springs

I've been wanting to do the same thing for a while, although for different reasons. I think the easiest way would be a modification to the swingarm to move the bottom shock mount.

Be aware that raising the rear doesn't only alter the looks, it also changes the bikes geometry and any changes will affect the bikes handling.

yeah that is understandable but i was thinking if i lower the front id get ore down force equal as to if i was to highten the rear and leave the front because more down force equals more grip correct me if im wrong.

would prob be a better idea on raising the height to adjust the rear subframe rather than mess with the handling surely? Just tilt it up a bit by extending the lower arm of the subframe maybe

ah just looked at a pic, it wouldnt be that practical to do that, would mean the seat would get deformed and the plastics wouldn't mate up properly

but just a bit of modification to the fairing would fix it though, infact i dont think youd have to its just the part of fairing next to the seat that will need unbolting from the frame so that the rear end could move up slightly, no biggy.
