dude you have no idea how wrong you are....Well, I think that post is sorta right. From what I've heard, the stock ECM limits the HP in the first few gears to 100hp. By putting in a TRE you remove this limitation. That yellow "chip" is a standard resistor chip with a 5th gear resistor in it.
So, ya, they're selling you a resistor for $20. And technically, in first gear, that will probably boost you 43 hp.
It's just a resistor TRE.
only in some countries in europe are the bikes limited to 100hp, for the most part they are not, and i dont think what is being sold on ebay is even a tre....
