I ordered this filter to go on my 2000 XR100R- which the site said would be compatible with my bike. When I got it in and took it to my mechanic, he said it was definitely NOT compatible with my bike. The clamp system wouldn't work with the permanent filter on the bike. All that was needed was a foam piece which we were able to obtain from a local cycle shop.
I have no complaint about the product, only that it was not compatible with my bike.
