Nevada is the same for motorcycles. If you don't test with a manual xmission motorcycle, you can only get a moped license, whatever they call it, but it allows only the automatic transmission cycles.
The only restriction I saw from DMV's website is:
"If you take the test on a motorcycle of less than 90cc, your license will be restricted to 90cc or less (Restriction U). If you take the test on a moped of less than 50cc, your license will be restricted to 50cc or less (Restriction Q). "
