Guys, this post is from June. Retail on Hotbodies is indeed $700. In November Hotbodies always has the crazy 50% off deal which sometimes it extends past November if not many people buy them and have sets left (for example I once bought a brand new full set for a CBR500 for $240 because they had leftovers and it wasn't a high selling item). So at the time of this post, you couldn't find them anywhere below $700.
Also I wouldn't worry about the number of posts. OP is with the Quarterly Racing team, which is a professional MotoAmerica team. Last season they had 3 riders ride for them in the Junior Cup class, all on Ninja 400s. They are legit, I've talked to them before (mostly Bob), they have some great bikes and know what they're doing. Sometimes race teams get aftermarket parts after which someone else comes up with something better or due to sponsors they have to switch to other brands, which I think was probably the case here. They had other really nice parts for sale that were also brand new. But you probably won't get much response via the forum, best is to contact by phone.
