Could be EFI but not validated yet...06 is still a recent release....you will have to wait to December for any 07's..other than that no info :ride:

i asked becaused dident the dealers meeting just happen? though ther might be info floting around..........

No this would be in June...... :ride:

Yamaha is going to have to work really hard to improve the '06 YZ450F. What a bike!

I'm thinkin blue, a carburetor, a slightly different steering angle and a higher set of pro tapers.

Oh, slightly different graphics too.

Quiteter muffler too!

Looking really good that they will have EFI...

according to TWMX and other sources, the only manufacturer that will have EFI for 07 is honda on the 450. all i know is that if it is honda or yamaha, i am buying it. i want EFI!!!! :ride::banana:

Well, a pretty reliable source who is inside Yamaha to a degree stated that it looks like EFI for next year. He didn't say 100%, but it is good enough for me to think it is going to happen. He actually said he'd be surprised if they all didn't have it, but couldn't be confident in Kawi's plans...

The problem with EFI is the battery to power it....right now the weight range is 7-12lbs....that is the problem Houston.... :ride:

I dont think the battery is going to be needed. Snowmobiles have had batteryless EFI for years.

I thought EFI was illegal in the current AMA rulebook.....am I wrong?

EFI would be absolutely awesome!! it's strange that in Japan and Europe they can race EFI yet nobody in AMA is running them.

what exactly does EFI mean to starting, jetting and electronic ignition?

they cant run EFI right now because it is not on a production bike

I just got my new MXA mag and they said the main problem is the battery but it was just a general Q&A article nothing specific

EFI should be awsome. I couldnt wait for it though! should be an awsome bike!!! :ride:

it would be cool don't have to mess with jets . :ride:

Remember, that issue is new, but the Japanese Nationals were quite a while ago. It's sounding more and more like it is going to happen...

You're way behind. Read Transworld's article in the newest issue (Got mine yesterday). You'll get a techno briefing on how they are going to do it. Hell, one company is incorporating the kickstarter in to get juice to the system. Crazy...Awesome, but crazy the technology is so damn good...
