I have that type from arrow motorized, better than stock. I'd save a little more and get something bigger if I were you, I'm already looking for another to install.

I have one like that, also from Arrow. It works fine, provides a very noticeable boost in bottom end and midrange power, and has proven to be durable. I've had it on my bike for a couple years now, and couldn't be happier.
