Yes there a little different(better IMO) different from stock. There available either direct from silhouette or from webike, not really hard to come by if you got the cash.

Your notice the extended lowers at the back and the wider suzuka style nosecone, these are also incredibly well made.

EDIT: just thought tho if you go the silhouette route you may aswell buy the VFR version which is exactly the same but it fits a VFR funnily enough They also do a slightly different style for the VFR too.
