Ivan needs to hand over the bike outside of Yangon city limits to comply with local laws. He was gracious enough to give recommendations on where to go and what was a good option. he speaks Burmese and has been living in the country for over a decade.
He let me know you could ride a machine from Yangon to Mandalay one way, or vice versa, and drop the bike off. Amazing option. They will even pick or drop off the bike up from your hotel.
Ivan has many big bikes to choose from but is limited to a few scooters. Perhaps with more demand they will expand their fleet to include more automatics.
The other option in town isn’t allowed to rent bikes now and another shop has some horrible reviews that make sense to avoid.
Please make arrangements in advance with Ivan to get your ideal situation since he has to coordinate with the Mandalay branch. good luck exploring Mandalay.
