Honda CD 100 is very good and comfortable bike
average is above 50 Km/l
handling, road grip and break is excellent and for more better than CD 70
major disadvantages
more road clearance, if you have low height, this may be problem
steering cut is shorter, difficult to U-Turn on narrow streets
Kick is very hard, specially in Cold weather, may be the problem is solved in new models.
Overall this bike is great in 100CC category, resale is good now a days, not comparable with CD70, but good
