    Awesome. But I think bigger can be achieved. Someone should make a GN800 kit

    All factory power measurements are at the crank! So of course it is!! Both those measurements will be at the crank...

    Why do people not get this? Factories do not give you RWHP cos it seems like less, its always crank power!!
    Yeah, nah.

    Same reason they actually believe some of the hp claims from fitting an aftermarket can.

    because it is an kit, not the Suzuki factory, and it's a gn, not a gsxr, so forgive me...

    Damn that's only $220 plus post with today's exchange rate. Tempted to do it just for a lol, plus the bragging rights of having the fastest slowest bike in the country.

    OOOOOHHH - there's also a slotted front brake rotor!
