The reason the Bandits are priced the way they are, is they don't attempt to incorporate all the newest technology. If you brought the B12 up to date with all the trendy stuff, it would be a $10,000 bike, at least.
The Bandits are a good deal since they use some old, proven stuff from older bikes, along with some cheaper components.
A little lighter, more power, fuel injection, and better suspension is cool with me. Suzuki ought to be able to dive into the parts bin and come up with a new B12 with that stuff.
