That is exactly why.
At a Weld vender display at a drag meet several years ago,I asked why motorcycle wheels are 3 and 4 times higher than popular custom drag racing wheels,like the drag lights I run on my truck.The answer was because people will pay the price.:deal:
Aren't they Billet? That would make them cost a little more then say the cast 5 spoke they put on the F, but by no means justify's the price. I'm guessing thats why they're so heavy.
I have them on my bike and they definitely slowed it down going from a the solid w/ a 180 to the reactor with a metzler 260. I had put a 26T pulley on a long time before that and the reactors slowed my bike down more then the 26T helped it accelerate.
