The old C50/70/90 were brilliantly practical, stable & economical machines with solid, simple engineering & basically bulletproof.I did this maths 6yrs ago - six years later - nothing viable has come onto the market place to replace a/my Honda C90? (AFS 110 108cc Honda C90)
Simple question?
(no bullying please )
Unchanged today they they'd make a superb buy and transport solution. Cheap on resources, cheap to run, durable - brilliant things.
If your 110cc more modern variant is half as good, then that'll still make it about 50x better than so many alternatives.
In terms of bang-for-buck & frugality - it's a tough act to beat.
The only thing they don't have, is any cool cachet for those who value image over, well - value & practicality.
