EBC after market discs have a good rep. I'll personally vouch for Armsrong waveys and also Stealth waveys. Be aware that some people have had trouble with the Stealth, so it's your call. There are some reeeeeally cheap Chinese made waveys on fleabay that I saw but didn't really look at (I personally don't usually head for the bargain bin when it comes to brakes, but will find a decent price for good quality stuff).
Standard discs are errrm 'very Honda' ie well made, with top quality materials and presented with top quality prices.
Just replaced mine with Armstrongs from here-
BCT Talked to the fella and got them for £299 the set. I am lucky though, coz I can collect from there so no postage costs.
As for calipers, I haven't noticed a problem with the originals that a service kit or the odd new bleed nipple wouldn't cure, so never really explored the possibilities. For me, I don't mind spending money, but it HAS to provide a benefit that's worth the cost. The prices of 'race' or billet calipers are just, well---- eye watering
and a matter for the individual I reckon
Eliminate the impossible. Whatever remains, however improbable, must be the part you forgot to service.
