Speedo healer v4.0 zx6/9
 

I'm selling my speedo healer got in november last year and was used until march this year and is set up for a b1 1 tooth down in front sprocket this can be reprogrammed easy, it fit a b1/b2 and rr models I think it fits zx9 as well but not sure although you can buy harness kits.

Also has the top speed record button.
