Wayne Rainey: Yamaha’s 2009 YZR-M1 is best GP bike ever

Yamaha legend Wayne Rainey reckons Valentino Rossi’s current YZR-M1 800cc machine is arguably the greatest MotoGP bike ever built. This year’s factory Yamaha has firmly established itself as the dominant force in MotoGP racing after the early 800cc dominance of Casey Stoner’s Ducati Desmosedici. Italian Rossi and talented Spanish team-mate Jorge Lorenzo have won nine races between them in 2009, adding to...

Another no-sh!t sherlock call

Of course it is. It's the latest thing out there & it's doing all the winning. Dominant? Not as much as the Doohan era NSR's or Rossi era RCV211. Maybe Rainey is trying to belittle Vale a touch by saying such things. Comparatively in my mind Rossi's M1 is similar in performance to Rainey's YZR500's - excluding the 1992 model  - a winners ego will last him a lifetime.Yamaha's generally have been the best handling things out there without quite as much engine as the Honda.

Pneumatic Valve Spring + Crossplane crankshaft

Just want to point that the 2007 Stoner Gets the upper in terms of Speed because his desmocedici Valve wont float even if the engine cranks upto 19000rpm why  because of Desmodromic Valve Timing. So you may observe in all around aspects of the circuit the ducs speed never faltered in all aspects of the circuit.

Now comes the M1 and Honda uses Spring Valve timing, and at 19000rpm they are prone to Valve Float so you may also observe in straights this machine tend to slow resulting to loss of Power. The Yamaha was aware of it so they Introduced a formula 1 Valve Timing System known as Pneumatic in later stage of 07 but the engine tend to be unreliable, but they never gave up and push that direction in 2008. Inspite of some of the critics that it will be unrealiable and added weight to the bike. But their Development effort had resulted to Yamahas fruitful year. In short if you ask where the M1 got their power, the answer is in their Engine and it started in 2008 and that is the Pneumatic Valve Timing. Hope it clears up everything Up... Dont Under estimate the M1 if you drive it will be scary this bike is a monster in straights so much more its awesome agility will be more outstanding than it used to be in 2005.
