will 07 450r style plastics bolt on the a 2003 300ex?

[Sjorge450R]

no. The 07 uses a plastic tank design like the 450r. There is no acual plastic covering the tank itself. Not sure on the rears tho

[bwamos]

as above said.. so it's a yes & no answer.

You can but you'll have to buy a seat, tank, and lighting also.
