Only direct swap I know is the 2006 Paul Smart Ohlins.
Aside from that your options are:
2005-2007 Monster S4RS and Evo 1100S Ohlins forks.
BUT.....while the forks fit the top and bottom triple, you will
NEED to either shave the front radial calipers to clear the spokes OR switch to other wheels. Alpina and Kineo spoke wheels I think clear, along with all the cast and forged non-spoke wheels.
Not including the master cylinder change, it's enough parts that need changing to discourage me at the moment.
