They aren,t only talking chassis. A sled is only as good as it,s weakest drivetrain link. Blowing belts will not get you home. How many belts should one have to carry to go a thousand mile trip ? Maybe they start coming with a caboose, full of belts, as standard equipment. I,ll stick with my Yamaha Apex RTX. It,s not the lighest, and it,s not the fastest, but I have the confidence that it will get me home, from every trip I take. And I do have a choice, cause I own a older very reliable Cat as well, but it just sits in the garage, looking pretty. The newer ones, looks like they should be just sitting in the garage as well.
