As the Honda Forza is from 2006, we can assume it's a Honda Forza 250 (NSS250). In Thailand we only have the Honda Forza 300 (NSS300), which was first introduced in 2013.
It's very possible that some Honda Forza 300 parts are similar, but I would not recommend you buy parts for the Honda Forza 250 without checking if they're compatible.
If you really look for specific Honda Forza 250 parts, I'm sorry to say that you will find that they're very very rare in Thailand. As the Honda Forza 250 was never sold in Thailand official....
I am living in Cambodia and have a 2006 Forza and I need to find a parts dealer with brake parts and disc ?
I hope someone can help , Thanks
