Also, keep in mind your F3 is still going to vibrate at 60 mph from the imbalance of the engine. Our 3 cyl engines will never be as smooth as the first 2 cyl power plant Can Am's.

Just a note. i installed doc humprey's vibration dampener which is far from being a piece of plastic, by the way. a very nicely designed and milled piece of kit he has. Just mentioning it as numerous folks who tried the BRP unit have had to replace it several times due to it's construction materials and workmanship.
Also, our 2016 F3 limited has 0 vibration at any speed. we feel nothing through the foot boards, seat, or handlebar, whether it's 30mph or 80 or anywhere in between.
Like the OP I will never get over the gall of BRP in this respect. It just takes huge attachments for a company to improperly engineer/design/manufacture a product that universally exhibits this type of flaw, and charges the customer to fix it.
