tyre monitor

Agreed there is a way that the Explorer ones can be replaced if you have the nouse - it does tell you how on the Explorer forum - but given that you can only get at them with the tyre off, a tyre fitter is not going to wait a couple of hours whilst you cut, de-solde and rebuild the sender unit from within the tyre. The only way would be to have a spare set you take with you at tyre change time.
It may be different on other Triumph models, but certainly from reading the Explorer forum it's not an easy thing to replace the batteries yourself on the Explorer senders

You're right and I think they are all the same crap design.
