Hello Guies, If you are looking to rent some dirt bikes while in Siem Reap with a guide to discover Cambodia, I can recommend you Hidden Cambodia Dirt Bike Tours Paul (he is cambodian) who is taking care of the business is a really nice and funny guy. He knows Cambodia on the back of his hand and will take you off the tourist track. He has mainly some 250s, Honda XR and Honda Baja. Contact details are on their website! :happy2: Keep riding!
