Hey roamr,
There are actually uite a few different options. There is a company in the UK call f1moto.
Here is their gallery link
http://www.f1moto.co.uk/They make subframe kits for the Gen 1 bandits swapping to the following.
MV Augusta, Yamaha R1, sv-650, and quite a few others.
You will almost 100% positively have to cut your existing subframe off. Unless you have some serious skills in metal work and can just modify the current frame.
Don't know if this helps you, but it gave me some great ideas of where I wanted to go with mine (Gen 2).
Thank god my friend had the skills and access to a lot of the tools needed.
Later.
