The Honda CT 110 is a small motorcycle manufactured from 1980 and on. It's essentially the CT 90 of the 1970s but with a slightly enlarged engine. In 1980, Honda increased the displacement by 16 cc, or 18%, over its CT 90 ancestor. The transmission is a four-
My particular Honda CT 110, serial number 5,006,649, dates to 1980. It’s powered by the original one-
It incorporates many changes developed on the basic CT 90 layout through the 1970s. Compared to systems on my 1968 CT 90, the breathing system is routed further back, the instrument gauge cluster is redesigned, and there are turn signals, actuated by a switch on the right-
Notice the strange little black reserve fuel container hanging on the rear. It's the original and is much prized by collectors of these bikes.
I got my 110 from the same brother-
Deferred maintenance. I completely disassembled the carburetor, cleaned out various gum and other (aluminum oxide?) deposits, and reassembled. The bike got a fresh battery. It needed little else to restore it to more-
Upgrade. The Honda 90 had shown how it could get us way close to superabundant High-
This was done by obtaining an old CT 200 wheel, on Ebay. No large sprockets were on the market at the time, but a complete wheel was (rotted, rusty, bent spokes, who cares), incorporating the odd, large, rear sprocket of the CT200. Naturally, everything but the target part was discarded, and the desired sprocket was installed on the CT 110. It went on with nuts and bolts beside the existing rear sprocket. There it is in the photo to the left. Effective tooth count went from 45 on the existing sprocket to 68 on the modification. Theoretically, the bike's hill-
Naturally, the chain received additional links to accommodate the larger sprocket. The chain guard needed to be removed, as shown.
Useage. I've driven the 110 comparatively little in the 14 or so years I've owned it. It's given me a few joy rides around the neighborhood. It's amazing the emotional lift one gets from doing a few loops around local blocks at 20 mph on just a little Honda 90 or 110.
Finally, to test how the big rear sprocket would perform, I put the 110 to use on a wilderness fly-
Here's the bike (below) parked near the end of the road beside a meadow at almost 9,000 ft.
From here, I hiked cross country to this tiny, never-
and then moved on to this lake, where I landed this respectable, tasty brook trout.
So that, my friends, is where an old Honda trail bike can get you.
