We worked closely with Polisport to manufacture blue fork boots for the ATC250SX and the ATC200X. These are the correct size for the 85-87 ATC250SX and 83-87 ATC200X giving them a stock OE appearance and not the universal Ebay oversized boots look. They are made with a silicone material just like our other black fork boots. Not only do they hold tight to the lower forks but also the upper fork tubes. In most cases you don't even need to band them. Also, these will look great for a long time as well as last much longer than any rubber style boots. These are a great factory look without having to use them oversized Amazon and Ebay boots that are just too big and rub the tires in some cases. Also, less than half the cost of OEM rubber boots that are no longer available. It's a Win Win!
