Are you on holiday in Thailand and visiting Nan in North Thailand? In Chiang Mai it is very easy to rent a scooter and even big motorbikes. And although Nan province is a great place for motorbike riding there were until now no shops that rent scooters & big motorbikes. Yes some Hotels or Guesthouses are renting scooters but no big motorbikes.
But now there is "Tono CarRent @Nan". A bit weird name for a shop that rents out scooters & motorbikes but it looks like a good & serious shop. And the guy running the shop is friendly & service minded. He can pick you up from the airport and bring you to his shop.
His shop is located in the new shop-houses behind the bus-terminal. He rents out scooters like Yamaha Fino and Honda Forza 150. But also an off-road Honda CRF 250 and they even have 2 big motorbikes (Kawasaki Ninja 650 and Suzuki Vstrom 650). And he also has some riding gear.
He claims to personally own the bikes and that all motorbikes have an standard insurance. You will have to pay an deposit that depends on the kind of scooter or motorbike you will be renting. And you will have to show & copy your ID. All the scooters & motorbikes look like recently new and well taken care. Have a look at his Facebook page Tono CarRent @Nan
