I've been looking around for a small but reliable air pump to carry on trips, came across this > Best Products < which seems pretty good, has anybody got, or had the use of one?
I've made my own, starting from a cheapo of about 10EUR, tore down the plastic housing and made an aluminium box around it. Looks a bit like the TT one, except for the manometre. I didn't keep that, because I have a digital pressure gauge that's quite precise.
If you really don't want to spend to much and have something that will last long and cheap enough to replace try this link......

Fit the correct adaptor and off you go for under £16.
After reading a thread on this subject on the ADVrider site, I'm quite tempted to fit a small compressor in the space I have under the tank, ahead of the battery* (where the ABS pump goes - mine's non-ABS). It could be permanently wired in, with an air line long enough to reach either wheel, coiled on top of the air cleaner cover. I've got a cheapy compressor that would probably do the job - is it reasonably straightforward to fit a length of hose (I'm guessing just a jubilee clip)?
I use a small U.S high pressure bicycle handpump from Halfords. It goes up to 40psi, one version has a sort of pressure guage in it, and it is short enough for me to strap it to the air intake tube under the tank edge. Used it several times, works fine, cost about 12 quid. Can't say the physical effort was especially hard either.
