    I have the athena 280 My bike rips now! It has more power at a lower rpm I can lift the front wheel without having to clutch it or down shift to get the bike to respond.
    The install was easy I had to remove some material from the outside of the cylinder skirt to get it to fit in the case but that was it. I also installed a 2007 R head with stainless valves and a hot cam.
