Behind the scenes at the Yamaha World Launch in Sydney, I got to check out some of the new, advanced components & technology that have gone into the new R1. I found this really interesting, being mechanically minded myself, so I thought I would share…
A connecting rod would normally be made in 2 separate parts and then bolted together but even with dowels and bolts its not perfect and can flex. Now its cast in 1 piece with a fault line where it can be purposely fractured into 2 parts and then joined perfectly back together.
These photos show some of the improved components…
Photo 1 shows the new lightened crank, titanium rods and high compression pistons.
Photos 2 you can see each gear is hollowed right through instead of just where the dogs engage, every effort has been made to reduce weight.
Photo 3 shows on the left the 2014 starter motor and on the right the unit for 2015.
Photo 4 is a complete motor cross section to see the assembled internals.
Photo 5 its not visible in this photo but after casting each head is machined by CNC to make each combustion chamber perfect.
It’s really nice seeing the technical aspects of racing, nice post
