32HP seems very low for 660cc?

Where did you get that info? Did you try contacting KTM yet? Good luck!

I get that info here on the official KTM web site

I think that model comes out of factory with restricted power and would like to know how to do it full.

If 1HP = 746W, then 21kW would be 28.1HP. That just doesn't seem right for a 654cc bike.

I would think so as well xrider1. I would contact KTM directly and see if there is some sort of way to open up the bike. In terms of maybe removing restrictive exhausts or intake snorkels. I think even the stock XR650L all plugged up has more than 32HP.

I was doing some reading on the net and found a few sites from mainly Dakar and rallye riders who run the KTM 660's. They seem to be able to achieve around 60-65 average and a high of 75 HP. You are correct if that is what KTM's site says. But it does seem awkwardly low. Good luck!
