Hello All, 
 
This is my first post, and my first Yamaha! 
 
What’s happened is the f/r/h/s disc has started to warp and I have been looking to replace this part.  
However, along the way I have stumbled across sites where owners have converted to R1 discs and calipers... 
 
Is this easy conversion and is it actually worth doing? 
 
Any info will be appreciated. 
 
Thanks 
 
Moosa
