my rear tps has already been replaced. the front is just now giving the low battery warning when temps are in the 20's or lower. so i know end is near, but warranty will cover it. as far as the warranty...standard is 3 years unlimited mileage. it also has an extended three year warranty (6 total) for around $500. i say its worth it for a couple reasons. most people say extended warranties are useless, and thats usually true, but think about this... this is a first (now second) year bike...ALOT of new, untested in time technology. there is a masssive amount of electrical things on this bike. the enemies of electronics are temp, vibration, and exposure to elements. our bikes encounters all three. SO, the cost of the warrany, 5 or so years from now, will MORE than pay for itself when the ecu or kipass, or whatever system goes tits up at 100k miles. hopefully that wont happen, but that $500 will give me some great peace of mind when this bike rolls 6 digits on the odo. even if your bike doesnt rack up mileage, it will still rack up the years. i say get the warranty...you can purchase it at any time during your existing warranty.
