Pricing for both not officialy released but from Yamaha they are saying it will be at or lower than current MSRP and from BMW they are saying the new RR will be at the same price point the HP4 is.
22k from VanDuc for a 14 HP4
15k for R1
Perhaps not half the price, but ill take that extra 7k
However, actual purchase price will fluctuate depending on where you bought it and when.
