Go to Fowlers and order everything you need to save on postage, what happens with buyers the size of Honda is they design it and put the specs out to manufacturers for supply quotes who say yes please we want to supply gazillions of those.
Back when Triumph went metric they buggered up big time by asking the bearing suppliers if they could supply main ball and rollers of a specific size and were told yes but didnt ask how much so in saving a bit on retooling plus machining they spent 4 times the money on bearings, what they should have asked is what is the most common metric size close to this

Thanks
I managed to get a NOS Kawasaki 92057-1011 chain for £45 so a good saving. Interestingly it is made by Morse who are a long established chain maker, I believe they originally started making chains in the West Midlands in the late 1800s.
