Yamaha yellow with black speed blocks, just to confuse people. No stickers, let them work it out for themselves.
Or just make up a non-existent name:
"XZi 450"
That'll get them wondering what the hell just went past them!
I've always thought that the tail plastics date the bike horribly.
Everything recent has a nice pin-sharp tail, but the rest of the fairing isn't really that dated.
So I have had a play on the rear of mine with gaffer tape (alright, I haven't bothered taking it off since Op Storm in the summer)
A black lower half of the tail slims it down visually, but I was never really happy with where the boundary line (between yellow top and cowl, with black beneath) should go for best effect.
And a black bellypan and wheels makes it look less slabby in primary colours.
But try it on Photoshop, and you will see what I mean.
But I just bought a spare tail plastic with intact lugs as a spare, so I might just start playing again.....
It's not falling off, it's an upgrade opportunity.
