Nobody knows, but it's most likely because of production costs. The 4D System has Beyblades with multiple parts for their Metal Wheel and their 4D Bottom is a combination of various pre-exisitng Bottoms.

Hasbro probably didn't want the price to increase, so they used the same number of pieces they previously did; of course they had to modify them.

It still sucks in my opinion, because they changed the colours, decreased the weight by about 10 grams, and even used weird pre-exising Track/Bottom combos for Beys.

AD145WD on Beat Lynx? WTF?
