I would love a longer warrantee also but we have to look at this in realistic terms.
I have snowmobiles, waverunners and an ATV there is no comparison between them when it comes to taking a pounding. ATV's just by their nature are more dangerous and take a lot more abuse (even if your a mild rider).
I feel while riding all of the above I get as aggressive with one as do the others but have never flipped, fallen off, gotten hurt or done any damage to the snowmobiles or waverunners I can not say the same for the ATV, I don't think I have been out yet that something hasn't occurred. Let's face it we are driving these things in the worst possible conditions and when those conditions aren't bad enough we consider it boring and look for worse condtions.
I'm not saying I like a 6 month warrantee I'm just saying I understand it.

As far as the safety course I agree if it saves just one kid it's worth it.

Just my opinions.
