I also have a carbon (harris) fender currently on my bike which was a replacement for the original scratched OE fender on my SP5. Whilst looking ok on my bike, the mounting points on the SP5 fork legs are about 5-10mm higher than on stradas and so I would like to get a new OE fender, so that it fits tighter to the wheel, as this fender is ideally for a strada/DS (silver fork legs). If I can get an OE fender, the Harris one will be available. Any interest?
Paul I'll get back to you early next week, as I'm away for a few days. I must inform you that this is based on me having a OE replacement in my hand before you get it as otherwise the bike is without one! Nat Legs are different. I had a strada at the same time as the SP5 and the legs (and forks are different though both Showa) easy reference is that SP legs are bronze in colour - but believe me the differences exist or I wouldnt be after a new fender!!!
Just waiting on confirmation from JHP that OE is available and not a back order then we can talk about a price. BTW - what sort of price are you getting on Pirelli Diablos - saw you were using them on a different thread.
