Anyone out there using this Tire Pressure Monitoring System for Motorcycles?

I like the idea that the same sensor can mount inside or outside the tire... So I can buy it today, and use it today, without having to remount the tires...

But I'd like to hear from any owners/users of the system.


PS. Trying to find out if just slapping the sensor on the outside would throw the balance off. The sensor weight is given as 0.67 oz, which seems like a re-balance would be in order. I'm also curious if you must (initially) use the stems provided (i would think not, if you already have metal stems).
