Hook, you can do some homework. Kuryakyn sells a lot of stuff for metric bike pegs that require an adapter (specific to the valk driver or passenger mounts) mounted to a universal peg/board that has no mount. IE you can fit any number of things to the valk driver's peg location, so long as it mates to a Kury valk driver peg adapter. This is mostly pegs or peg kits with swingdown stirups, etc, but may include floorboards (without ends). I finished off my bikes many years ago, and do not keep up with this stuff anymore.
One thing many have done at the driver position is to use Kury ISO Wings without ends, mated to the correct driver peg adapters. It is about half a floorboard, but for about half the price of floorboards.
This: 1.

And OK while looking that up, I discovered no Kury floorboards without ends are designed to fit the valk driver position (passenger, yes). Pretty sure the reason is simply how small the available space is at that position for standard size driver floorboards, since the valk is center (mid) controls, and the valve covers (and shifter placement) limit the possible size of valk driver floorboards. Cobra boards for valk driver are simply a set of their smaller passenger boards, adapter to fit the smaller space available.
I think most with driver floorboards use Cobras (me too). I was unaware you could get MC enterprise boards alone without the full heel toe shifter as part of the package and that kit is pretty expensive. But the MCE boards are larger than the cobra, if large feet is an issue.
*But when considering boards, you have to be aware that depending on foot size, and if not using a (now discontinued but probably still available used) Rattlebars peg lowering kit (which I
think Westsider has in the pic of his bike with MCE boards), installing driver boards can lead to difficulty getting your toe on the shifter (and many end up moving it one tooth on its spline mount, up or down). And some others have replaced the valk shift arm entirely with a longer one off another model honda (CBX something, sportbike?). This problem is also solved with a heel toe shifter which I think most guys with boards use (me too, and with no peg lowering kit). But no heel toe shifter is availble anymore new, except as part of the MCE kit. Otherwise it's back to used Rattlebars or Kuryakyn. On the other side, there is no issue with the brake at all.
With cobras, looking like this.
Traditional boards

Swept boards

Some things to consider before spending for parts, installing them (making them unreturnable), and finding out they are not working quite right for you.
Also, I think Custom World International out of Quebec CAN may sell floorboards for Valk. All their stuff is well made, but very expensive and shipping to the US is not cheap either. I'm not researching that site, it may be in French. LOL
