Waaaaaaaaaaa

Been thinking of getting one of these, and putting the warning light up by the brake cylinder. It triggers if pressure starts dropping and gives you a visual indicator that it might be time to stop the bike and do some checking of the tires. So far just thinking, but it's not that pricey, might be cheap life insurance.

BE VERY CAREFUL of TPMS systems. My tyre place used to sell them but reckoned that one out of three would always have issues with at least one wheel - and on the R3 I simply cannot get ANY sensor to signal well to its' receiver from the rear rim. Often only picks up if I stop near something and the signal can bounce - which is a bit of a waste of time if you're doing 400km trips on open roads. Even more annoying as I wanted to monitor tyre temperatures.

Without cases etc you should have a better chance. But place the receiver off to one side - as little metal and electronics twixt transmitter and receiver as poss. When you think about it - it's obvious really.
 
Yeah, the sensors would be on the right side on mine at least (angled metal stems) and the receiver would go under the right side cover. But it can't be that impossible to get it to work, they even say you can mount the sensor inside the metal rim. But of course, never tried it so...
