I was actually looking at the same set on amazon and my only thought was if the throttle tube that was already inside these grips would work with our bikes. Did you have any issues? They LOOK like they should and the dimensions seem right on the amazon page.
I like the 'flat' throttle boss on the spiked one as well, but I don't like the spike all that much.
