Buying A New Shineray / Platinum / M-Bike / Keeway / Sym / Lifan Ect Motorbike

Hi. Does anyone have any recomendations for dealerships selling the above "enduro /dual sport" type motorbikes in or around the Chiang Mai area. I will be moving there, from England, early next year, and untill i find a suitable house with a secure garage (when i will purchase a KTM 350 / 450) i will require a road legal off road style bike. I was a motor vehicle technician, so some spanner twirling is most welcome in order to modify / adapt the bike. I will be using it mainly for locating and exploring off road tracks in advance of ordering the KTM. Top speed or road manners are not a concern. To all the "cheap bike" haters out there, dont bother moaning they arent as good as a xxxxx, because i expect that at 35% of the price! I only require something cheap, that will be consined to second bike duties once i order a 430,000 BHT KTM. Any positive help,information and advice welcome! I will be over again around June time to put your information to the test. Many thanks in advance JEFF.
