i have a saxon tour 1995 model rotax 500cc motor
it came with a 18 tooth engine sprocket
in slow town traffic it was way to tall gearing
i went to a 17 tooth and it was much better but is still
a bit tall but i use it for touring
if your use is town and roads posted 60 or less
a 16 tooth may be even better
rotax.net
has engine parts sprockets and even hop up
parts
