Chck this out guys, it might be interesting to some of you.
http://www.bandousa.com/html/pdfs_industrial/bu-200_power_trans.pdfCheck out pages 14 and 89 for the 14pitch x 40 wide belts, makes good reading. Looks like the profile is right.
Also stopped by the local Suzuki/Kawi dealer and told him we were
lengthening our swingarm, and the owner said it wouldn't be a prob
for him to find a longer belt, so they are out there.
The Bando's in this catalog are STS series. The Sukuki belt is a UTS
series, but don't think it affects the profile.
A polyurethane blend belt may be more UV resistant or something,
the STS belts here say they are neoprene.
I'm no belt expert for sure! Just passing on what I've come across
on the net.
