What is the best pipe to install on a stock SR50s for all around diveability other than stock?
What is the size or call numbers for the drive belt if not going to a mother honda?
Last but not least; I hear people talk about metric vs ? tire sizes. If 3.50x10 is the largest that will fit the SR50, is there a size between 3.00x10 and 3.50x10?

Greetings:
The only thing that comes up in a search for 3.25x10 is an inner tube from a Vespa site. 90/90x10 should be about 3.54" wide, but I've heard tell that they're a little narrower in fact than 3.5s. I have no direct knowledge. ANyone with a set mounted and calipers that could measure?

Veedubh20- I have 9,000 miles on the stock variator and belt now. Belt measures 15mm, but I don't know how wide the original belt is, to compare it. The variator does have some very slight waves in it.

Standard NB-50 AF05 Belt is listed as 15.5 mm. in the Service Manual. Confirmed by measuring my new belt from Honda-san.
The belts don't wear all that quickly because they're always "engaged" and the slip happens at the clutch. Unlike snowmobiles, where the clutch releases and grabs the belt itself - 3-4 belts per season was typical.
