    Is price a factor? I went with TB as it was much more affordable

    Price is not a factor. I only care about the most power for the street since I don't race on a track.

    7K on the TB cam is when the bike wakes up, which I don't mind at all since I live around (and above) that RPM anyway.

    They're identical cams... TB copied their cam off the DCR R2, so take your pick lol

    I went with the TB Cam and had the reflash by DHM as well as purchasing the cam from them. I got great results at a reasonable price. The grom now feels more like a real motorcycle and the power continues to build all through the power band. Drop a tooth with a smaller front sprocket and you will have good acceleration and power for anything except high speed roads (where you have no business being in the first place). But that's just one opinion. The Grom is all about creating something fun, it is a blank canvas after all! Have fun!

    The Koso cam gave me more of a well rounded improvement vs the TB cam which took away low end power and favored high rpm power.
