Well Yamaha have been the first to seriously dip their toe in the water with their R1,instead of going the electrically software route for traction they have altered the firing order by changing the crank shaft the same as Yamaha and hence the firing order.
What you are seeing is Triumph starting to reap the benefits of contacts they have made with running engines in Moto2,but straight forward it might not be,if your not a follower of Moto GP Yamaha have struggle extracting topend power,something that has past all but unnoticed when Ducati went from their classic 1098/1198 long stroke cam belt motor to the Panigali big piston short stroke camchain it has been a bumpy ride in more ways the one.
But Triumphs 765 and the new 900 shows that they are really starting to make an effort and we now live in a world of short stroke/big bore and other variations.
