As someone who loves to frequently take their motorcycle out on the road, I was hesitant about trying out a new protective shield for my engine but after I put it to the test, I was impressed with how well the Qiilu Universal Motorcycle Cylindrical Waterproof protector held up against harsh weather conditions. The automotive-grade material is tough and durable, while still being low maintenance. The only downside is that it can be a bit difficult to install. Overall, I highly recommend this protector for any avid rider looking to protect their engine.
