The GB was styled to look like an early British bike. I saw one at the Honda shop in
Gilroy, CA, in the early '90s, and from across the show-room, I first thought it was indeed
a British bike. (I also thought my Seeley was a British machine when I first saw it from a
distance; turns out I was half right.
)
If I recall correctly, the GB originally came with a hefty price tag, like $4K, and they didn't
sell very well, much like the earlier Ascot. Why the GB's are so expensive is a mystery to
me as well. Perhaps it is the "sand-cast syndrome"? I heard of an "in-the-crate" GB that sold
for $10K, and that may have convinced owners that their bikes were a goldmine..
