How do I inflate them?

Each set comes with a 12vDC blower to inflate and deflate your Knockrz. It conveniently plugs directly into your trickle charge connector on your motorcycle. It comes with a battery harness and cigarette adapter, and a 12 inch nozzle. The fuse on the stock battery harness must be increased to 20 amperes. A 20 amp fuse is included. Most “air mattress” type blowers will work as well.

TIP: It is best to remove the valve and inflate Knockrz as much as possible, then screw in the valve and finish inflating using the stop valve. Faster, and saves battery time.

Do you install them on a painted surface?

We don’t recommend that anything be in contact with a painted surface while being transported. We have found that the material we use makes great contact with a metal surface and does not move around. All surfaces should be very clean before using. Knockrz can be placed in three orientations to optimize the best fit for your application.

Can they be put on a hot motor?

Short answer is NO!

They should be deployed as the very last step before leaving. If you can hold your hand on the contact points, then you should be fine. Make sure all contact surfaces (including Knockrz) are very clean.

Is there any warranty?

There is a simple manufacturers warranty for 90 days from purchase date.

How durable is the material?

We inflate and test all Knockrz before shipping to make sure they remain inflated for at least four hours (if there is a leak, it is detectable after 4 hours). The 0.5mm nylon reinforced material is very strong and puncture resistant. We have used a number 2 phillips head screwdriver (which we believe represents the sharpest object on a typical motorcycle) to demonstrate how difficult it is to puncture. Sharp objects will puncture the material.

How much weight will they support?

We had an independent lab test the compression strength, and they found Knockrz would support up to 500 pounds of dead weight.

What happens with altitude changes?

Quite frankly, we know the air volume inside the Knockrz changes with altitude, but have not had a failure yet to determine how much change would result in a failure. We recommend that you check them with every 1000 foot increase in elevation to determine how much to adjust the air within. The reverse applies as well. We will update this FAQ as we learn more.

Do you have the patent?

Yes! The patent number is US 9,187,025 B2
