very interesting video I found about yamaha being the only manufacturer of a cross plane crankshaft for the R1..... many interesting points in this video us xs650 guys will knowtice and even the RE phase guys will appreciate .... I knowticed the number 270 degrees while watching and then decided to share it here, you have to have a real mechanical mind and some patience to watch then entire video, but being a moterhead or gearhead myself I found it VERY interesting, YAY Yamaha!
