Suzuki looks sweet Mr Bozzy, but you need to put your name on the fairing screen or we won’t know who’s riding it.
The RB and F2B screens are the same size so a pattern one should fit.
900 wheels will fit the RB but the RB wheels are wider which does allow for wider tyres.
I’m not sure if the 900 discs fit, the front disc has a sequence of slots around the center where the RB has a solid black line, so they are different. However I am aware of an RB owner who had 900 front discs fitted, I’m not sure it he had 900 calipers and maybe even 900 forks as well.
The seat looks tatty but if the base is good and you don’t want it I’d make you an offer.
