Quote Kunihiko Miwa,Yamaha's Senior Executive Officer
"We were thinking about the new engine concept three or four years
ago. the cross-plane concept makes a very good feeling. engine with
good power characteristic but with an
in line four it is a very wide
motor. The R1 engine is very wide, too wide, and we considered a twin
but the triple was the best solution using a crossplane crank design".
Its like I have a brother...
