I have a Loncin dirt bike and recently popped my tire...this is the first time I've had to replace the innertube and I'm confused...

I need to replace the front inner tube and the tire says 1.85x21 in one spot and 2.75-21 on another spot...

I understand that I need a 21" tube/tire but what width? 1.85 or 2.75? Note above that one has an x between the number and the other has a - (dash)...not sure if that matters...

any of you do work on dirt bikes?

Paging RDB to the white courtesy phone, paging RDB to the white courtesy phone!

RDB wouldn't know. his parents would just buy him a new bike if the tire had the audacity to *KERPLOW*

im probably wrong but i think on regular bikes... the bigger number is the size the fork has to be for clearance.

err so the thread doesnt scrape it i mean.

i think im wrong about that... but there is a vehicle selecting thing here. o.O

Well considering it's a whore to change the inner tube on a motorcycle, I may just bring it somewhere and have them tell me what tube I need and have them fix it...

kin if u live near boston i'd try calling parkway cycles in everett... they service pretty much anything so they could probably at least point u in the right direction... i have a shitty old honda motorcycle and they were the only place around that would not only order my parts but also service my bike from time to time...

I'll look into it...

I may just patch the innertube...
