Rare Rally Kit: 1968 Honda CM91 Rally

Disclosure: This site may receive compensation from some link clicks and purchases.

I think we’ve only seen one other example of a Honda 90 with a Rally Kit here on Barn Finds and they’re fairly hard to find. I know that they aren’t a big, bad Harley, but for those of us who are into unusual, vintage Japanese bikes, this looks like a winner. The seller has this 1968 Honda CM91 with Rally Kit posted here on eBay in Bellingham, Washington, there is no reserve, and the bid price is $635.

You can see the skeleton of a regular Honda 90 under that add-on gas tank, or actually, a CM91, which is also called just a Honda 90. The CM91 came out in 1966 for the 1967 model year and it was basically the same bike but with a new OHC engine. The seller says that the rear shocks and side covers are replicas, as is the fuel cap.

Honda’s “Custom Group” included four variations of the new CM91, two that added a new gas tank and two others with slight modifications, but kept the look of the original step-through design. This is the Rally, which supposedly gave the otherwise meek-looking Honda 90 a “competition look”. The narrow gas tank and contoured seat give it an extra kick.

There was also a Roadster kit with a bigger, wider gas tank meant to give the 90 the look of a “big bike”, and two others without added gas tanks, the Boss and Student. The CM91 was available in black, white, and red, as with this example, and they were a nice upgrade for those who wanted an easy-to-ride step-through bike but wanted more power for street and even highway use than the Super Cub 50 had. The CM91 brought it up into the 55 mph range, which if a person is on a backroad without a lot of traffic, might be just fine.

The engine is Honda’s 89-cc OHC single-cylinder, which had 7.5-hp, and the seller has added a new carburetor – a CT90-style carb – to replace the original one, which had water damage. The cases show the usual wear, but it has a new battery, new Michelin tires, Honda fuel lines, points and plate, and a lot of NOS Honda bolts. This bike has a three-speed semi-automatic transmission and it’s said to start easily and run well. For this price, this is a no-brainer. However, for those of us who aren’t in the Pacific Northwest, shipping will be a factor, unfortunately, because I’d really like to have this one. Have any of you seen a Honda 90 with a Rally Kit?

    When the owner of the first Honda dealer in Carson City died a few years back he had a bunch of sheds on a piece of commercial property he leased out. In it was one Ike this (of which I’d never seen before) a 1st year Honda 750, a GL1000, a Scrambler 90 and an S90-the 750 and the S90 still in their crates. There were other bikes too (all Hondas) though I wasn’t privy to how many more or what they were.
    His son I’d heard sold them all and kept the land/buildings leased out.
    It’s calling your name, Scotty!
