Well I've never bought an extended warranty on anything ever and certainly not on a bike the thought of doing so on my Tiger/1100s or XT are laughable in fact the XT never went back for the 600 service I couldn't be bothered knowing that I didn't need the warranty.
Which brings me to my K do I trust it? no I don't the reason I keep it it's fast and I enjoy riding it and most importantly I can afford it anyone reading this that has caviar taste and fish and chip finance I'd head for the exit door asap.
There are several ways to own a K.
That'll be the DIY job like Tom and there's nothing wrong with that I do the same with my other bikes
The take you chance and have it dealer serviced and take it on the chin option
Or the extended warranty and that'll be the 12 month version because the pay month option isn't transferable which in my book is a major downer if you come to sell it.
BUT
It's not all bad news I've felt from day 1 of the extended warranty I've always had a better deal not only that the bike is looked after but I see allsorts of recalls etc the majority I've had done before even being mentioned on the net the cam chain tensioner and the jump guard were done years ago in fact when I asked about such in 2013 they has been done 2 years previous I hadn't asked and they didn't bother even mentioning it they were just done.
I've had 2 clutch's in 3 if you include the original it's not that they stopped working but they were like a bloody light switch and it was sorted.
If you have a 1300 then I'd say you have a sporting chance of doing without but anything earlier you out on the gang plank!!
For me the question is 'When do you stop paying'?? baring in mind in 09 they reduced the cost down by 50% down to 300 quid
