Soichiro Honda (the REAL Mr. Honda) was all about the details on everything that he built for his customers and that included keeping the bikes and the riders as clean as possible. Even the bikes built in the early-mid 1950s had over-sized fenders and enclosed chain guards to keep the bikes’ drive chains clean for long life and to keep the lady riders clean as they maneuvered through Japan’s mostly dirt roads in the post-war era.
Stubby, little mudflaps showed up on the 1959 CB92s (front and rear) and the 1960 C110 Sport Cub 50s, which appeared on U.S. shores just after American Honda Motor Company opened up their Los Angeles offices in mid-1959. Honda’s “Touring” CA72-77 250-305cc Dreams had hidden front fender mudflaps to help prevent mud/dirt from collecting up inside the voluminous fender cavity. While not a mudflap, exactly, the 250-305cc Honda Dreams used a rubber packing to help seal the front fender/fork interface from dirt and rust buildup. Reproduction replacements of those packings (in gray or black) are available from www.claussstudios.com, while www.classichondarestoration.com has the reproduction front fender mudflaps available.
Rear mudflaps were always a feature of the 1961-67 CB72-77 Super Hawk lineup, followed by the “Chicken Hawk” CB160 editions which arrived in June, 1964. When the CB160s were replaced by the CB175s, the mudflaps carried on, until the 1971 CB175K5 series, using the CB160 parts. CL (Scrambler) versions of all of those models did not have the mudflap features, however.
The S90 (Super 90) street bikes were fitted up with rear fender mudflaps, as were the following CB100K0-K1 editions which used the same S90 parts, apparently. I did notice that there are two different part numbers for the S90 mudflaps, so some changes were made and require checking your frame’s serial numbers to see which is right for your bike.
While the 1973 CB125S bike was built upon the CB100 chassis design, Honda appeared to have decided to delete the mudflaps on all of their street machines from about 1973-onwards. Despite being in the “mudflap era,” the 1965-67 CB450K0 Black Bombers never featured any mudflaps on the rear fenders, nor did the SS125A Super Sport street machines of 1967-68.
So, if you have one of the mudflap bikes and need to replace those ancient rubber parts, what do you do? Fortunately, for owners of the CB92, CB160 and CB72-77 Super Hawks, various sources have remanufactured both the rubber mudflaps and the corresponding brackets (CB160 brackets have not been reproduced as yet, however). CB92 mudflaps came in several colors, including a very pale blue for the early bikes, superseded to black on the back fenders and white on the front fenders. CB72-77s used the same parts throughout the production run. The CB72-77 parts all have an -010 suffix on the part numbers, so there was some earlier version used in pre-production that was redesigned for final use.
Mudflap reproduction sources include: www.olypen.com/retro, www.claussstudios.com, www.ohiocycle.com www.classichondarestoration.com and various Asian eBay sellers. So, don’t get all in a flap if you haven’t found your mudflap yet. They are still out there and more are coming into the pipeline as demand continues.
