Probably a good moneymaker for Yamaha. I'd be curious what they actually cover as warranty and what is excluded as 'abuse' or 'normal wear and tear.' I could see wearing out the dogs on second gear, or needing a rebuilt head sometime in the 100k miles, but the guts of most modern engines are pretty bomb-proof these days. Lots of other oil makers outside of the bike world will offer engine warranties for exclusive use of their products (Penzoil for example gives you 15 years or 800,000kms if you use solely their synthetic oil) and I've never heard of anyone 'cashing in' on them.
