I emailed them about distribution to SA and their response was:
"We are offering shipping for this kit all around the globe. During check out process on our website, the system will calculate the shipping costs for you."
I also asked them about dealer possibilities and their response:
"As for distribution of South Africa, we already have been contacted by Yamaha’s distributor of South Africa to handle the distribution of our product as well, unless this deal doesn’t work out, we will unfortunately not be looking for other distributors in that country.
There will be a possibility to become a dealer under the distributor on the other hand. In the mean time, as the deal is not sealed, you still have possibility to reserve some kits from us directly."
Let's hope this materialises soon. Will be good for Yamaha in SA.
