About National Cycle

This windshield features 4.0mm thick Quantum hardcoated polycarbonate, offering significantly greater impact resistance than conventional acrylic or Lucite plastics. Its innovative quick-release design allows for tool-free removal when used with a separate National Cycle Quick-Release Mount Kit.

Ehhhhh, it's, , , , , , ok, , , , , read below

OK, First things first, this is a LARGE windscreen. If you are looking for a windscreen that will virtually isolate you from all incoming wind ( and BUGS! ) then this windscreen is GREAT! However, , , it is BIG. I almost sent in a return request though, NOT because of how big it is, but because of how it mounts !!! The bottom 2 "mounting brackets" that attach the screen to the forks, are literally 2 HOSE CLAMPS and 2 plastic brackets. :-/ <br />Of this I was so NOT impressed. I was going to sell my OEM Harley Q.D. tombstone style windscreen, but I will keep it and put it back on after the huge mass of spring / early summer bugs dies off some. This will be a seasonal use windscreen.

Awesome shield

When I received the shield I thought the brackets were a little flimsy but after installing the shield it was solid as a rock. Cuts the wind 95% which I needed for comfort. I'm an older rider and can stick my head to the side to get the wind in my face when wanted. Overall happy with my purchase.

I put it on my Yamaha MT-07

I know this is sacrilege for some, but I put it on my MT-07 with no modifications. It actually looks better than expected. It's a bit further and front than ideal (in front of the headlamp), but I think it's ok. No need to buy handlebar guards now. Seems to be better quality than a Puig I had, which crapped out in high desert winds. This one has attachment for both the handlebars and the fork, so it looks like it's going to stay on there. It feels sturdy. We'll see how it goes. <br /><br />Disclaimer: Your results may vary, use as intended, follow instructions, and use at your own risk.

Excellent product and very quick service.

I am very happy with my purchase of this windshield. It looks to be a very heavy duty windshield and it suits my needs perfectly. Installation was very simple and The hardware looks to be very sturdy. I would recommend this product to a friend. I have not had it long enough to express the durability but it looks like it should last as long as I don't wreck it. Write your review here. It must be at least 25 characters long. Consider whether you would recommend this product and what you like or dislike about it.
