Well i just spoke to the Australian distributor for yokomo and the good news is it looks like the YZ-4 should be on the shelves by the end of the month early next month, the bad news is its going to retail for $850, that would just about make it the most expensive kit on the market, nearly $200 more than the X-ray xb4 ,For that price i hope it includes every possible option or else they can just leave it on the shelf.
