Trail 125 cargo sidecar build

CCjon · 2026-02-16T21:08:43Z

Ok guys, am turning to the group for ideas, suggestions, warnings and insight. Bought a very low mileage (showing only 38 miles) 2024 Honda Trail 125 to haul on the tail of an RV to use as a campgrounds scoot. But... I want to add a lightweight (probably aluminum) cargo sidecar to it. My thoughts are: 1. Reduce countersprocket teeth from 14 to 13 for more torque 2. Raise handlebars and seat for my height 3. Add USB outlet for iPhone 4. The bike weights 260, need to keep total weight with sidecar to less than 325-335 5. Use a narrow bicycle type wheel or similar for sidecar to give more ground clearance and easier rolling. 6. No brake on sidecar 7. Locate mounting spots on bike for subframe and upper struts 8. Will be keeping speed to 30-35 mph, tops. No Alaska backroads planned for it. 9. Plan to keep a narrow wheel track, +/- 26-28" c2c If you have already build a creature like this or have been planning a sidecar build for the Trail 125, would love to hear your thoughts, suggestions, problems encountered, solutions, etc. What are your ideas ??????

There has been no discussion of performance enhancements to the Honda. A turbo would make you the coolest kid in the RV park.

Until a sidecar rig can do wheelies, the world is incomplete.
