On the 13th of September he was talking about the V4 being at a very advanced stage.
Why Yamaha’s rumoured radical MotoGP shift is bigger than just an engine Now it's sounding much firmer.
I wonder if we'll see (and hear) it at the end of season test this year.
Twitty mate, you have to stop basing your information around what Journalist write on Crash Net, they are just story writers, some may have even ridden a bike, but that would be the extent of there technical knowledge.
In the article that you have quoted, Lewis says, In very basic terms,
“
an inline-four is not as powerful as a V4. But the narrower shape of the inline-four allows more flexibility in chassis design, and therefore those types of bikes tend to have nimbler handling. This was a characteristic of the Suzuki too when it raced in MotoGP with the inline-four.”
Well with pneumatic valve engines the inline 4 and the V4, the inline engine has more friction, but can produce the same torque as the V4.
“
But the narrower shape of the inline-four allows more flexibility in chassis design, and therefore those types of bikes tend to have nimbler handling”
I think he got a bit confused here, it’s the V4 that is narrower and has the nimbler handling, the Inline 4 that has the wider crank that has the stability in corners.
Then we get to this bit ‘in theory’.
“
The move also coincides with MotoGP’s shift to 850cc engines from 2027. In theory, if Yamaha can get a V4 onto the bike for 2025 and develop it in a good way, it should give it a boost when the 2027 regulations come into effect.”
As I have said before, that would be two complete engines they would have to design, a 1000cc and an 850cc built and perfected in two years. Then they can’t just swap the engines into the bike, the whole chassis would have to be designed and built to suit each engine size, to produce good handling.
There is no doubt the they will go to a V4 850cc engine in 2027, we might see some action in 2026 as they start testing the new 850 bike under wraps some where, but until then they will be getting the most out of the inline 4, in braking, handling and traction.
