For those of you that would still attempt to mend a puncture or replace an inner tube at the roadside, as opposed to dialing up the rescue services, I have found a particularly good little pump, it will not fit under the fuel tank and would look out of place anyway, but at 350mm long would probably fit in a tank bag or panniers, it is manufactured by Topeak and is designed to suit fat tyre mountain bikes, I could give you figures for the amount of air it pushes per stroke but all the details are on the net.
It is named Mountain Morph and costs around £18.00 from Wiggle or Chain Reaction, and is manufactured by Topeak, all seals and O rings are replaceable but probably never need to, last time I went to use my replica under the tank pump the dished leather washer was in two pieces, useless, I can't be bothered with little gas canisters and carrying an electric pump seems a bit of an over complication, for me, this is the answer, hope I never have to use it.
