Released in 1968, the Honda CB350 and its scrambler sibling, the CL350, quickly became a massive success. The 325cc parallel-twin engine was reliable, efficient, and surprisingly quick for its size. It replaced the CB77 Super Hawk and went on to become one of the best-selling motorcycle models of all time, with over 250,000 CB350s sold in the US alone. The CL350 variant offered high-mount exhaust pipes and off-road styling cues, broadening its appeal.
Collectors appreciate the 350-twins for their classic styling, mechanical simplicity, and excellent parts availability. They represent an approachable entry point into the world of vintage Japanese motorcycles. They're easy to ride and maintain, making them a practical choice for enthusiasts who want to put miles on their classics. The huge original production numbers mean there are still plenty of examples to choose from, ranging from basket cases to fully restored show bikes.
The market reflects this wide availability. The average price hovers around $6,000, which typically buys a clean, running, and largely original example. The low end of the market is filled with non-running project bikes that can be had for under $1,000. At the extreme high end, prices can soar past $25,000 for perfect, low-mileage original survivors or professionally executed custom builds showcased at events like the Handbuilt Show.
Buying Tips
- Check the camshafts and rockers, as they are a known wear point. Listen for excessive top-end rattling on a cold start.
- Inspect the original wiring harnesses for cracks, fraying, or bad repairs. Ensure the charging system is working, as weak stators are common.
- Decide between the CB roadster and the CL scrambler. The CL's iconic high-pipes are often rusted or damaged, making clean originals difficult to source.
- Ask when the twin Keihin carburetors were last cleaned and synchronized. Poor running is often traced back to dirty or unbalanced carbs.
- Verify the frame and engine numbers match and correspond to a clean title. Paperwork can be a major hurdle on bikes that have been sitting for decades.
Prices range from under $500 for non-running projects to over $28,000 for concours-quality restorations and bespoke custom builds.
