I think one thing that will change is the importance of staying on the oil change schedual. The frame will not be used to release some of the heat from the oil. Our motors may run hotter and require checking and changing the oil more then some (me) are used to doing. The oil will run hotter making it break down faster. The oil quantity may be less also making schedualed maintence very important. I always buy the extended warranty on my bikes for the big problems that may come up with the new bikes. Thanks Mark The oil in frame/engine difference is a good point. If it does make for higher oil temps then an oil cooler might be a good mod for owners looking for longevity. I think I will invest in an oil temp gauge of some type and compare temps with my brothers 04 YZF450.
