120 on a 1.40 rim. Too big?

[Spyke]

I have bought a bucket racer a little while ago and it came with a 120/90 by 18 tyre on the back and its sitting on a 1.40 rim. Is this to big? to me it looks to big, If so what size should i put on.

Will this width affect my cornering.

also if anyone knows where to get a cheap tyre thats the right size drop in a pm please.

Hahahaha.

nooo way jose!

ideally a 3.5" for 120

Can cram a 90 onto a 1.6, but isn't ideal.

Must have pictures. Sterling effort!

got a few photos.

on the rim it says 18 by 1.40 but is that right, i measured the outside of the rim and it is about 55 mm which is 2.2 inches. but where do they measure the rim from?

i think i should get another tyre for it.

[xwhatsit]

Whoah! Coolest bucket ever!

That is all.

[F5 Dave]

Looks like a balloon! Nice.

The 1.4 is measured from the bead, ie where the tyre seats. It is a skinny rim, but so be it. A 3" tyre (~ 80) is about what you should be running.

thanks for the info, i did think it looked like a balloon.
ill have to try and find a resonable tyre.

What's all the tin for, if you don't mind me asking?

[TygerTung]

Is that a CB or a CG?

its ct125e

the guy before me did some extensive work on her because if im right thats a dirt bike frame.

the tin is on there i think mainly to stop your foot or gear getting caught in the wheel so that you can tuck your legs in to the bike more, plus it makes it look better.

Q- are you customising your cb250 to make it look like a cafe' racer?

because if you are that is what i really want to do too when i get a road bike!

Ah I see. I suppose with the rear-set pegs, you are dangerously close to the drive linkage ^_^.

Yep, haha. It's going to be an on-going project, it has to be done inexpensively. I'm taking notes from Motu on how to draw a project out as long as possible :innocent:. Cool! The more customised bikes on the road, the better as far as I'm concerned. Cookie-cut bikes are kind of impersonal in my humble opinion, unless of course they are concourse original-style bikes.

yea the legs would be in a pretty dangerous spot, i can just imagen myself getting caught up in the wheel or something.

i just love seeing custom bikes, they just stick out from the rest. i personally love the style of the cafe' racer styled bike.

Some of the bucket guys run a Ching Shin skinny down here (dont know what model) but they seem to work ok and are under $50 per tyre. They're a 90/90-18ish. Dunlop do a TT900 in a skinny 18" but $130 or more.

do you guys think theres any point of putting a smaller tyre on the front
? its a 3 inch metzeler at the moment but i was thinking of putting that on the back.

I'm nobody very smart, but I would've thought on a bucket that the narrower tyres the better. Less rolling resistance, so more top speed -- and on such a super-light bike, I don't think I'd be worried about losing either end, with suitably grippy enough rubber. Take a look at some of the hardcore 125 race bikes out there -- the front tyre is very narrow.

yea thats true.

i will keep an eye out for skinnier tyres, recommended width anybody?
