Parker Yamaha has them for $89 and the 3 up rear mat is $42, OEM mats. They are PSA, pressure sensitive. Peel and stick. Hydro-Turf will have them, Black Tip will have them. Just sit back and wait for the wide array of colors to accent your Spark. If I got a Pineapple 3 up I would get Hydro Yellow/black Camo cut diamond.
Sorry for the following :rant:
Everyone keeps forgetting this is an ENTRY LEVEL SKI. Forget the fancy iBR, and yada, yada, yada and just ride it. Our old skis didn't have it. Look at it like a car seat for your kids (those old enough)---we all grew up without them and we made it this far, so pull up your big boy swim trunks and just buy the stripped version. I'm surprised no one has compared the Spark to an ink jet printer. Get them in on the low entry price and get them on the inks (accessories) and make your money off that, pure marketing genius. Remember, no one is twisting your arm to buy the "extras" YOU control the final price of your ski, guys have become accustom to the gingerbread. I would buy mine with nothing, give me a spot for a Gatorade and I'm good to go. Heck, ride an HX for a weekend and you will learn real quick that you have just enough space for your car keys and wallet and that is pushing it.
