2009 Yamaha YZF-R1 released!


After providing as much speculation, information and product renderings to readers as possible, we can finally spill the beans on the much anticipated R1. Yamaha has pulled out all the stops with a ground-up re-do of its iconic literbike. New bits abound, including its styling, chassis and, most intriguingly, a MotoGP-derived firing order of its innovative engine.

In the top class of roadracing, engineers have battled with harnessing the huge amounts of power and getting it to the ground efficiently. In 2004, Yamaha's GP engineers introduced an uneven firing interval for its inline four-cylinder M1 with what's called a cross-plane crankshaft. Instead of the two outer and two inner pistons rising and falling together, the R1's engine has individual cylinders firing 90 degrees apart from each other. This eliminates the torque fluctuation of a typical four-cylinder mill, plus it gives the Yamamotor a very distinctive exhaust note similar to that of Valentino Rossi's racebike.

"It gives a much more precise feeling in the throttle action," says Yamaha's product planner Derek Brooks. "You fill like you can sense that edge of traction."

Well, I'm sure that it will be technologically superior, but it definitely lost the good looks of it's 2004-2008 predecessor. Took some ugly styling queues from Honda's 2008 CBR 1000 I see.

What's up with those headlights? Look like bugeyes from that angle. I like that color scheme and the matching seats though.

I thought so too. But apparantly not.

I like the new look, the bike looks stouter and more compact which seems like it gives the rider more controll over the front end, the lights/intake is a new idea that will prolly give it big buck in sales, and since I was wrong about the "all bikes were 90degree...", it has new technology that none of the other competitors have. Also since its a 'redesigned model' it will make it a big champ in sales in my opinion.... but they have to figure out how to get past that ugly fender bracket thingy in the back

I will work to elevate you, just enough to bring you down.

Easy on the throttle, steady on the gears, roll her over gently and she'll last for many years.

Do you mean the license plate bracket? Doesn't everyone remove those? I dislike the looks of those on all bikes, myself.

I have mixed feelings about the looks but those headlights have got to go.

So i was thinking it looks like a bush baby. or one of those praying mantis. I was down at the local shop, there is one there. they said its really heavy even with its dry weight. Im not a huge fan of yamaha so I really could care less of what they do next but from what I know it seems like an impressive bike. I just dont like how they feel the high seat. even though I am 6'3" i still love the feel of the gixxer.
