Can anyone confirm the wheel rim sizes for early (1973-75) Honda C50 and C90 bikes?
Im wanting to confirm what I need before purchasing new rims for my C90, told they are the same on Facebook so need to confirm....

Secondly the exhaust / muffler, do they share this item also?

Hi

Going on memory!
the C50 rims are narrower than the C90 120 to carry 225/17 tyres
The C90 rims are 140 to carry 250/17 tyres
I expect to 50 not to be an issue with wider rims but a very slight loss of top speed as wider tyre = more rolling resistance

I think the exhausts are the same on the per restricted bikes

Dave is a walking encyclopaedia on all things Cub, but the other place to do a bit of searching is over on www.c90club.co.uk (you do need to register first to see the forums but it takes minutes) as there's a wealth of information over there, for this and any other queries. Thumbs Up

Slight correction, very slight.
