I know the IMS tank now, with a full tank of fuel, makes it a bit heavier, but even with all the protection package and loaded with the bag system I have, I can still pick up the bike on my own without hassles, like I did my old motocross bikes. And I'm a girl. My 600 sportbike I could pick up too, but it was a modified lift that can be used on ANY bike that is heavy. Even A fully loaded Ultra Glide.
Bottom line: Is bike protection mods worth it?
On this bike? YES
Even with the weight of the bike, it sells. And Yamaha sells A LOT of them. It is what it is; a dual sport not a motocross, and even the competition can't claim the maintenance schedules this bike boasts. Maybe KTM uses magnesium components...but the price goes up, not to mention you still have to maintain it a lot more frequently and it's a bigger bike to boot. The bikes that are closest in competition with this bike aren't really even comparable in components, but I digress.
Protection on this kind of bike is a MUST if you ride off road, regardless if you use a piece of plexiglass or aluminum. The reasons are the same, protection. It's there to provide a job, protecting the bike. I'd rather spend $100 on a skidplate and not blow my case open when I hit a nasty sharp rock, than using absolutely nothing and having to shell out a whack on a new case, and lose ride time, all in the name of saving a little bit of weight.
