Just replied but the internet connection here in Nam Pat has let me down. Have had 2 sets of Metzler Tourance fitted, the most recent by the piston shop in Chiand Mai. They are great for high mileage and only changed them at 20k because i was going to Laos a few weeks ago. Have had a high speed off the next day when i hit a large oil spill as i was coming off the mountain. New tyres, loaded bike, new brakes and oil do not mix.
In Laos they were just great on the shite roads but if you want for the mountains go for something softer, less mileage but a lot safer. The scorpions sound ok.
