It definitely can make 56-57HP (or more with some major tweaks) and a lot of info can be found on this web Also check my showcase...

Thanks very much for the reply and info! What costs were involved with making that power? Power only - what mods would you need to match your figures?

Well - my bike is 2017 version so it's different from new ones. For 2017 MY European bikes you need a reflash, quick throttle grip, throttle limiter removal and snorkel mod (for increased air flow). In my case it was DIY project and I spent around 400 euros but I have some programming and mechanics background. In your case the biggest investment will be the reflash - don't know the prices in UK, here in Spain a reflash is around 200-500 euros. So, it's all depends on a tuner prices and his willing to make a bit of reverse engineering.
