In a show that they're serious about sorting out their engine issues, Yamaha have hired Luca Marmorini to help design their lump for 2023.
He was most recently behind Aprilia's move to the 90 degree V4 and a huge step in reliability, and was with Ferrari in F1 before that.
A big statement from Iwata.
At least that is what Gazzetta Dello Sport is reporting.
That is strange. Yamaha has very good experience with vee they just insist for Inline layout. I think 90 degree gives more torque but affects bike length ( maybe longer bike, wider space inside vee give better breathing to engine too, maybe high speed stability, more weight at front to prevent wheelie, more weight at rear to prevent stopie, these all can be advantages of longer wheelbase and 90 degree engine ) which Japanese makers didn't like or prefer.
When Yamaha insist so long with inline layout I don't think they will go for 90 degree. They may go with vee layout. I hope they will. In this case ( narrower vee) I think more power has bad affects on bike. I got this conclusion because of Honda's statement when they had more power with the engine previous years.
So building vee engine with better engineering which eliminate bad affects on bike stability honda had or building 90 degree with a very compact design which will alow them to keep shorter wheelbase should be aim ( according to me )
