No need to keep the Busa. The FJR is very fast to 120 -130 mph. It will do nice power wheelies in 1st and 2cd gear. After getting the FJR, I see no reason for you to keep the Busa, unless you still need that really high speed fix! Still, there is nothing like the power of the Busa and it's so arrow! The FJR will run 120 mph+ all day in total comfort, don't even need the visor down and it's rock solid!
The FJR is better for me cause.
1. Comfy.
2. No chain to fuss with.

12. Should hold it's value better than the Busa.
