MotoGP » No seamless downshifts for Yamaha


"Honda was the first manufacturer to introduce seamless upshifts to MotoGP, in 2011. Ducati and then Yamaha subsequently developed their own versions of the technology, which slashes the amount of time taken to change gears." NO IT DOESN'T!! What it does do is take out the torque spikes that otherwise result from decelerating the engine to match the new gear during near instantaneous gearshifts.

MotoGP » No seamless downshifts for Yamaha


The point is that you can't have instantaneous shifts without some way of absorbing the massive torque spikes you'd otherwise get. The main aim of seamless shifts is to have an uninterrupted flow of torque during gearshifts so that you don't unsettle the bike. If speed of shift is the aim, why are they bothering with seamless downshifts?

Insidejob:
Vilas46: A good article ultimatemotorcycling.com/suzuki-returns-motogp-exclusive-inside-story/
Thanks Vilas! That's an enjoyable read.
Not a very good article - it perpetuates the old myth that "High-revving (aka “screamer”) fours produce big-horsepower, but they lack low rpm torque. With their relatively narrow powerbands, they are harder on tires and the rider" Truth is that a conventional in-line four produces more torque and power just about everywhere compared to a cross-plane crank type. they feel more "torquey" because they sound andfeel like you're revving them less. The theory behind Yamaha's cross-plane crank is that it reduces fluctuations in crankshaft speed and so gives more consistent drive. Nothing to do with low down torque - just look at an R1 power/torque curve compared to its rivals

Can't help thinking an in-line four is a backward step. The v4 was competitive and only needed a couple of top line riders, Bautista hasn't done any better on an "almost" factory Honda, so it must have been good. It might help them to develop road bikes but will they sell any? Surely that's what WSB's for? Better to be at the front in WSB than be embarrassed in motogp. - go ask Kawasaki
