Rumour has it this is the 2010 yz 450f

Ok a pretty good source over at thumper says this is the 2010 yz450f .... With fuel injection at the front of engine, exhaust straught out the rear of the head, cast alloy bolt together frame ,electronicaly controlled rear shock,

Dunno may just be rumour but a pretty cool concept

OOOPPPS just read MR YAMAHA Isnt happy about pics getting out so have removed them

Interesting ideas, though got to say I reckon it's a fake ( two sets of front mudguards one @ front / one @ rear, petrol tank facing wrong way, air filter case pointing to radiator guard ).

over on thumper pics still up go to ..make model specific ..yamaha..yz/400/426/250 under 2010 yamaha 450

Guess time will tell not bad idea less damage to be done to header pipe. interesting part will be the tuneing due to short exhaust system and noise level would also have to be taken in to account with shorter exhuast.
I still want a 2010

you yamaha thinking while everyone else has done just the 450 as fuel injected they will have sat back and waited (not like the non injected isnt competive away) and bring out both the 450 and 250 inject at the same time and learnt from everyone elses mistakes.

yeah sorta looks like they may follow the europeans husa berg ,bmw crowd,with some of there ideas, and some of there own the artical also said the WR was coming out with the same stuff..But suppose we will have to wait till 2010 to find out..i know some 450 bmw's are having starting problems seems to be something to do with the wiring and ive seen one in the states with the cast chassis that has cracked in half

simple eveyone else honda suzuki kawasaki bought only the 450s out fuel injected so far.
Yamaha has sat back and waited learnt for their cock up and will bring out both the 250s and the 450s with injection.
