Speed Gems 2 Sapphire 17x1 question

[Toyotachris1982]

So I have recently purchased one of these Speed Gems 2 Sapphire motors for a vintage BK1 XXX project i have and noticed that they come at a seemingly higher price than the other Speed Gems motors. Is there a reason for this? Thank you for any help on this

Just random.

I have three of them and didn't pay much for them.

The only thing that might make a little sense is the color. With all the blue hardware and accessories, blue motors might be a little more popular.

That was my thinking as well is its likely the color
