Aluminum bar and plastics are high quality.
The hardware supplied for connection to the handlebars seems good.

The problem arises when attaching the plastics to the bar. The bar is pre-drilled, but not tapped. The screws provided are self-tapping Phillips heads. Phillips head screws are designed to prevent over-tightening, so using them here was a very poor design decision. Torx or hex would've been more appropriate.

Phillips head screws of this size are typically good for a maximum of around 2 Nm, but definitely no more than maybe 7 Nm. Installing the supplied screws into the aluminum bar required about 30 Nm of force. (Yes, I started measuring after breaking the first Phillips bit. For the record, I broke two) I don't know the exact torque spec for these screws, but let's say they're good for a whopping 15 Nm. More than twice the maximum for a Phillips of this size. You STILL need to apply 200% more torque to the screw than than it was design for. The result? Broken bits, stripped screw heads, and at least two visits from your girlfriend wondering what all the cursing is about.

I guess the rest of it is ok. But they lose a couple of stars for bad engineering.

I bought these hoping they would be good at blocking the wind and rain here in the northwest. Well, they do a great job of that. I had barkbusters VPS guards on my other bike and in comparison, I actually prefer cycras. This is not based only on their wind protection but, also on ease of install and an overall great design. It cleared all the cables on my old xl600 no problem and the kit even comes with additional spacers and bolts if you need to move the guards forward to clear a master or some cables. The center mount is easy to install and looks awesome. It does clutter up the area around the clamps so keep that in mind if you use a lot of Ram style accessories on your bike. Some review complain about the hardware to mount the shields to the backbones. While it can be difficult, I think most people are trying to force the screw in sideways. The side guards where the most difficult because you have to bend them and install the screws simultaneously. It's molded plastic so if it's really fighting you, just use a pair of pliers with tape over the teeth and squeeze them tight to the backbone as you start the screw. I wish the covers themselves didn't look like dumbo ears as much but, that's the only place these guards might get a lower rank. Overall I love these guards and will probably never go back to barkbusters because of the install, quality and protection the cycra guards have.

Very happy with the finished product. Installing the plastics onto the backbones with the supplied self taping screws was more difficult that I would have thought. I also chose to heat and bend the backbones slightly in order to have the backbone angle more perpendicular to the center reach clamps. No fitment or cable clashing issues.

I had 3 of the 6 screws for the hand guards not grab aluminum due to the predrilled holes being too large. Some cut in just fine. For $120.00, the buyer shouldn't have to use cheap screws and force them into unthreaded aluminum. I will be tapping all screw holes and using some loc-tite.

I have the non-CRM Cycra Probend guards on my other bike and I like the CRM shape better as it clears the cables better. The CRM's are also slightly lighter and allegedly more durable. What's not to like...other than the increased cost? They are great.

I could not get these to fit any one of the 3 bikes I have without extensive bending. And...since the inside clamp goes up from the bar, there is interference with brake and throttle lines. Strongly recommend another brand that will bolt on easily. Also, the bar end clamps are really soft and once clamped, won't thread off. I have used Enduro Engineering and Acer is and both are much better designs.
