  1. I can only assume (I know, it will only make an ass of u and me) that it is because they have concessions and/or any penalty will only be applied to the rider on it, which is their test rider Fernandez. Will be interesting to see if it does make the difference needed to properly run and be competitive with the other manufacturers though.

  2. I get test riders testing new aero etc just never heard of one being allowed to test what’s presumably going to be next years engine in an actual race weekend?

    I appreciate it’s a huge what if, but what if he actually wins or does something extraordinary to effect this year’s championship?

    All sounds a bit iffy to me!
     
  3. Moto GP is a prototype class... no homoglation rules. If it satisfies the rule book, then it's fair game I guess.. Harks back to HRC running triples and V4 500's back in the day.
     
  4. The concessions that Yamaha have does not have limits on engine development so they can develop and run whatever they like as long as it’s in the rule book.
