'09 Honda CRV: Bought new, TPMS equipped, 65K miles on the car, system works perfect, never touched.
'08 Kaw C14: Bought with 2500 miles on it, TPMS equipped, 27K on the bike, system only worked if it was above freezing, went through two sets of batteries in 15K, Kaw/dealer refused third, and I gave up on system.
The technology exists for this to be a trouble free, dependable safety feature. For whatever reason, Kawasaki not only laid an egg with the technology, but is less than supportive of it after the fact. There is no defense or excuse for advertising a safety feature, and then executing it so poorly that it is useless. If there is an aftermarket set of equipment that would work, it would be great, but quite frankly shame on Kaw for creating this issue.
BTW - my $2 tire gauge has been trouble free.
Just my thoughts.
