Ok, trying to bite my tongue, but can't do it and sleep.
I love the Spyder. I have been riding for almost 40 years, and it is my favorite bike. I have ridden dozens of different makes and models, in case that was a question bouncing around your head....
Now, to your comments..
First, the "Frunk" (which you pointed out how much you dislike that term?), but it's accurately called that since it is the trunk in front!
Second, It is not a gasket, it is a seal. That is also the accurate name.
Third, the reason it "pops off" when things rub against it is because it is a friction fit. Time and removal/reinstall stretch the clamping point, and make it weaker. The part is DESIGNED to be removed for cleaning and/or maintenance. Either re-squeeze it with duckbill pliers, or spend the 16 bucks every so often, and replace it. Multiple bike, auto, boat, RV, etc. manufacturers use the exact same design of seals.
Fourth, There are less "modifications" required on this machine than many others out there. There was a hell of a lot more things that were needed on the three BMW K1200LT's that I have owned than this bike. I wouldn't call seamstress tape a required modification. Parts wear out. Replace them.
Fifth, BRP takes great pride in their machines. So do I. So do the hundreds of thousands of owners. No product is without flaws or room for improvement. The reason I bought a Spyder over any other bike, is because I like TO RIDE, not spend endless hours in the shop, or fearing roadside breakdowns. She is very VERY dependable, stable, and comfortable. It is much more reliable than my Ferrari 308 was.....
Im sorry you have had such a horrible and devastating experience with your Spyder. I certainly invite you to apply for a job at BRP as an engineer to show all of those good for nothing pride-less morons how to build a toy that meets your standards- Or, just sell yours and end the suffering

Yes, I get it, everyone is entitled to their opinion. But an opinion without proper information is about as useful as teets on a bull.:banghead:
I hope you see the humor in my response, and not a personal attack....
