Parts fiches are available from Fowlers, Ling's and others.
Collate a list of all the Honda part numbers you need and then check on eBay for availability of copy parts. Most plastic clips are available for significantly less.
In fact, almost
every fastener on the ST1100 or ST1300 is available from Honda
car dealers or on-line for much less than any
motorcycle dealer will charge. Honda used all sort of parts across their entire product range of cars, generators, garden equipment, outboard motors -
and motorcycles - from nuts and bolts, special plastic fasteners, seals and bearings etc. etc.
The other manufacturer who makes cars
and motorcycles (namely BMW) does the same thing - but
all of their parts prices are pretty outrageous
(DAMHIK). The manufacturers like Yamaha, Suzuki and Kawasaki use most of the same fasteners made by the same companies (Honda and BMW do not make their own nuts and bolts etc.) but they don't always designate them using the same part numbers.
Anyhow, if you have a sample of the clip you need, just take it into the Honda
car dealership parts department and ask them to match it - or better yet, get the OEM part number off one of the fiche sources noted above and search for it on-line. Simply put the part number (with no words or other descriptors) into the Google search engine window - and press "enter".
You will likely be amazed at what comes up and in any event, you'll almost certainly pay a fraction of the
motorcycle part prices - because these fasteners are not
really a dedicated
motorcycle parts. Things like these plastic fairing clips and push-pins as well as most of the other nuts and bolts used on our bikes are actually generic parts used in all sorts of other applications.
The key thing is to have
the OEM part number - that information is golden.
