Honda S90 (Super 90)

1964 - 1969

All years and models of the S90 are great bikes. The one that are a little more desirable to collectors is the 1964 and 65 models with the offset intake and aluminum cylinder.

Offset intake 1964-65

Inline intake about 1966 and up

The very early S90's had an aluminum cylinder with a steel sleeve, as seen in the left picture. This was changed to an all steel cylinder that was painted silver in about mid-1966. There is no cooling issues with the all steel cylinder but the Aluminum Cylinder is more desirable for a collector.

	The early one piece steel cylinders look like the aluminum ones with the large idler sprocket bolt on the side of the cylinder and if they have not started to rust like the one in the picture, you may need a magnet to identify it.
This Steel Cylinder has the large bolt head like the aluminum cylinder and the steel cylinder pictured above but has a rectangular raised are.	The later one piece steel cylinder design can be identified by the small bolt head for the idler sprocket on the side of the cylinder.

The tank badges.
It can be difficult to find good original Honda tank badges. They tend to curl from exposure to the elements then it is almost natural to push on them to straiten them back out but then they crack and break. It is possible to straighten a curled badge with the correct amount of heat. If you have the screws, don't loose them because they are not a common standard screw.

Blinkers on a 1965 Benly 90 (Non-US model S90)

The early US S90 models didn't have blinker and when they did they were round. These small rectangular blinkers were never imported to the US.

6 volt Festoon bulbs are hard to find. The local Honda dealer says they are discontinued.
Honda P/N 34905-201-000 Winker Bulb (6V-8W).

I found some at Donsbulbs.com http://www.donsbulbs.com/cgi-bin/r/t.pl
They are 6v 10watt 31mm X 9mm
The new bulbs are 10w instead of 8w but work just fine.

The tool box is located under the seat.

No print date. From the early sixties based on the off-set intake.
Great poster, wish I had one.

Always check for rust inside the tank when purchasing an old Honda.
