857-1: Motorbike with Sidecar
This set came out in 1979. I went ahead and downloaded the instructions and started the build. The original was blue and gray, I went with the all Black styling. The single cylinder engine is basic, there is no suspension but the complexity of the gear to chain and the steering makes this kit a fun build.
I might modify this model and make it based on a 1-3-5 width build instead of the 2-4 6 width build.
