Yamaha Thailand sells the Yamaha YZ450F, not all Yamaha dealers know that. But they have parts for the YZ450F 2015, 2016 and 2017 models.
You did not specify which year your motorcycle is, therefore I included the YZ450F Water Pump parts catalog for the 2015 model. The part catalog in in English and Thai, which makes it easier for you to communicate with a Yamaha dealer.
You can also try to call Yamaha Thailand, not sure if you in Bangkok or somewhere else, but the main telephone number is 02-740-8000. They can help you, and speak English… something what is still rare at a motorcycle dealer in Thailand
Really, is the Yamaha YZ450F available in Thailand? How much does it cost?
Yes, the Yamaha YZ450F is available in Thailand. The Yamaha YZ250F is also available in Thailand.
The prices are:
2017 Yamaha YZ250F 275,000 THB
2017 Yamaha YZ450F 325,000 THB
Just to be clear, the Yamaha YZ250F and YZ450F are full professional off-road motocross bikes (MX Bikes), therefore this motorcycles are not road legal and cannot be registered.
I need some help please Yamaha YZ450 water pump seals where can i buy them from in Thailand tried many shops no one speaks English
