    Not offset I would say.  They are just OEM sprockets; see link below.

    PBI are the ones I use as I need an offset.  I use the table below as a reference (could not find your 2 there though)

    Yes they are a factory p/n but 33338-83 appears to be offset a little like here. https://www.ebay.com.au/itm//383255556401    I was hoping someone might confirm as some pics I find they appear flat and I couldn't contact pbi through the website. Nobody that stocks them had them on hand for measurement or confirmation they were in  a warehouse.A lot of sites use generic sprocket pics wich makes it even more confusing.

    Got yah.... I do not think that is actually an offset in the OFFSET sense of the word. But rather a small offset so that the chain will clear the gearbox cases.  If its perfectly flat then you may find that a 530 size chain would rub on the case.  
    You could dry fit something and see what the clearance is like. 

    Remember if you add offset to the front you need offset in the rear as well.

    Yes that's all good the primary is offset 1 inch already with an extended kicker etc and a 200 wide rear wheel. I made an offset sprocket by machining the center out of a flat one offsetting it 6mm and welding it up for mockup . But when I seen a pic of one that looked to be a similar I thought i'd try and buy one.
