Tested: Motorex Moto Protect corrosion protectant review


Date tested: April 2018 | Price: £13.50 for 500ml can | www.motorex.com


Motorex markets Moto Protect as being ‘particularly suited’ to protecting bikes when not used for extended periods. It’s easy to apply from the aerosol can, but the spray is rather lack-lustre, so will struggle to push the product up into the harder-to-reach areas.


Motorex Moto Protect performance

Despite the can boasting ‘long-term effect’, Motorex Moto Protect performed more poorly than almost all our other products. By the end of week two, the steel plate coated with it had 20% coverage of rust, and the metal was completely ruined by the end of the fifth week.

Fresh steel plates were cut to size, folded at 90° (to give vertical and horizontal surfaces), then thoroughly cleaned before being coated with each product, as per the manufacturer’s guidelines. The test was carried out indoors, with a reasonably regulated temperature. For more information on how the test was done, please watch the video below.

Morning and night, the plates were each sprayed with a 5% solution of road salt in water, then consistently rinsed off at the end of each week with a hose head set to a shower pattern.

After eight weeks, the hose head was switched to a more aggressive fan spray, and the plates were rinsed with a consistent five full strokes from a distance of one inch each time.

After 14 weeks, any products that hadn’t completely corroded were hosed off every evening.


Motorex Moto Protect stickiness test

After being left for 24 hours, the steel plate that was coated with Motorex Moto Protect retained little of the sand that was dusted on it to test stickiness. When rinsed, a tiny bit was left, and it was all removed when hosed with the fan head.



Metal plates were cut to size then thoroughly cleaned, before each product was applied as per the manufacturer’s instructions.

The plates were left indoors, laid horizontally for 24 hours, then each was dusted with fine sand. The plates were tapped vertically to knock any excess sand off, before being assessed for stickiness.

Next, each plate was rinsed with a hose head set to a shower pattern, and the amount of sand left was assessed.

Finally, each plate was hosed with five full strokes from a distance of one inch using a more aggressive fan pattern, before being checked for any remaining sand. Both rinsing cycles represent the methods used during corrosion testing.


Motorex Moto Protect safety on rubber

Soaking an O-ring in Moto Protect caused no issues with swelling, cracking or any other damage.

Brand new O-rings kindly supplied by motorcycle parts specialist B&C Express were put into test tubes containing each product. These were left for three months to soak, before the O-rings were carefully removed and assessed for any swelling, cracking, or other changes to their structure.

Please note that we do not recommend using these products as chain lubes – we’re just using the O-rings as a consistent material.


Motorex Moto Protect review verdict

Sold as a motorcycle protectant, it’s upsetting to realise how ineffective Moto Protect is. If your bike is ridden in the rain, Moto Protect will be of no use, and even it’s just left parked outside, this product is going to do little.

In our testing, some multi-sprays performed far better than this, so if you really want to prevent your bike from rusting, we suggest you use one of the better fluids reviewed below.
