I built up the Aoshima "Thunder Chopper" several years ago and I remember not being able to shake the feeling of deja vu during the project. It turned out that it was a rebox of an Imex "American Chopper" (Easy Rider) which I had built sometime back in the mid-90s.
What can I tell you about it? Typical Japanese manufacturing - decent quality, minimal flash, light parting lines, and good fit. It has the typical areas that many modelers feel need to be improved with most bikes (spoked wheels, drive chain, slightly oversized tubing for simulating wiring, etc.), but overall, the Imex/Imai/Aoshima bikes were fun to build.
