Help - What front end is this?

[gh129]

So I know it's not stock, I thought it was an MK2 but then I read that MK2 is a 3.5" rim, mine is a 2.5" rim.
The rotor is 320mm.

That's a Bros front wheel and not a MK2

Check out this Japan yahoo auction https://page.auctions.yahoo.co.jp/jp/auction/u460123812

Thanks, looks like mine the all the numbers match what I have on mine. This helps but I have to admit despite a bunch of googling I', still confused with whats a MK2 vs MK1 vs Bros vs NT650. Is this spelled out somewhere in the forum? I want to buy another wheel like the one I have for rain tires and knowing exactly what to call it and differentiate it will be a big help.

MK 2 wheels look like this

Bros are usually called NC25 or NT400, Hawk is Rc31 or NT650. Hawks little brother and maybe that's why it's called Bros. I think engine and ecu, wheels and brake/forks are different but pretty much everything else are the same

I have Bros front wheel but you might be on the other side of the pond I am assuming, and might have couple sets of MK2

I'm a bit closer then that, just outside Toronto, Canada. So next question would be... I have a Bros front wheel and i know that fits and works with my existing caliper (in pic above), would the MK2 also fit?
I am interested in grabbing one wheels you have preferably with a rotor

I only know Japanese specifications.

In the Japanese market, BROS is, as the name suggests, a brother of 400 and 650.
400(NC25) is called BROS P2 (product2)
650(RC31) is called BROS P1 (product1)

The L type is the so-called Mark II.

those brakes are all compatible.
Good Luck
