Motorcycle Repair/Honda Benly


Dear Bill,
I have recently aquired a Honda Benly engine no.C92e1074522. Chassis no 720030-45.
Could you help me with the year and cc etc. The bike is in Thailand.

Henry, some of the later Benly models have unusual serial numbering, but I believe that your 125cc Benly was built in 1965. Honda was using the first digit after the model to designate the year from 1959-64, then seemed to jump to using a 7 in the 1965 year. We didn't get any C92s here in the US, only the 150cc version CA95. The cc is stamped into front of the base of the cylinder block and should read 124cc.

Need help with vintage Hondas from the 1960s? I am an expert with 250-305cc bikes in particular and most all of the other pre-91 models, in general. I do NOT claim to have a great deal of experience on Gold Wings, Cruisers, ATC/ATVs and dirt bikes.


I have owned/ridden/maintained Honda motorcycles for 35 years. I have written five books on Honda repairs and collecting. I was a service manager for two Honda shops back in the 1980s.
