Some good news from Graham at High Side Tours (HST). On Mon 3rd and Tue 4th November 2014 they have exclusive use of Bira Circuit. They have 1 ER6N still available for hire for one or both days. 10,000 baht/day all inclusive [+ deposit].
Or you are welcome to join with your own bike for 1,200 baht. Please call to reserve as they are limiting the numbers. Please do not just turn up on the day as you may be disappointed if they have to refuse you.
For New Year they are planning a trip to Kaeng Krachan Circuit again. Probably the 29/30/31 Dec 2014 or possibly the 30/31/1. 4 x ER6 available at the moment. Contact HST for pricing packages with/without hotels, etc. Email contact is graham. [email protected]
