520 front sprocket for T500

Does anyone know if there is a 16T 520 front sprocket available for the T500? I have seen where the early RM250 sprockets cross but those seem to max out at 15T.

Going an extra tooth on the gearbox will turn your top gear into an overdrive and it'll be a pig in traffic.
If you really want to gear it up, you could get a 2 tooth smaller rear sprocket.

This isn’t for a original T500. I am dropping the motor in a GS500E chassis and it seems that the OEM 39T rear sprocket is the smallest available without getting a custom one. Just trying to get the gearing back closer to the 15/33 gearing of the T500. The 15/39 gearing won’t be horrible since this will most likely never see highway speeds for any prolonged periods but I also don’t need a buzz bomb either. If a 16t front is not in the cards and the 39T rear is not a good match once I get her on the road then I can look at a custom sprocket.

Might be worth while looking at this thread in another forum.

Alan H, thanks for the link. That is nicely done. I highly doubt mine will ever get done to that level. Mine was, I assume, a track day bike at some point as it has had a gsx600 front end swapped on, clip ons, and some safety wiring. I am assuming he is/was running the 15/39 gearing that I am trying to raise based on his comment on the low gearing. I am probably going to modify my down tubes a little different but the way he did it is very clean.
