Are you sure Lion Roar produce a motorcycle by itself?
They usually produce PE upgrade parts for others' kits, so plastic molding is not their line of production and business. Just my 2 cents.
You said you pay about $100 per armor, so you always buy PE upgrade kit for your armors?
As for dogs, I have three in the house namely Bank, Big and Brown. The first two are domestic dogs, midium size but the last one is a big golden retriever and the greediest dog that I've ever seen in my life! But he's cute and most friendly to all visitors:
Thanks for your info about the VK4502. Did you modify the kit? and what kit? I think I have some of them built before (Italeri's and Dragon's) but they don't look like yours.
