At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Motorex Joker 440 Synthetic Spray is a multi-use workshop product, promising to clean and lubricate, repel water, protect against corrosion, penetrate seized threads and stop squeaks. Sure, bike shop shelves groan under the weight of similar, cheaper products. However, it seems more powerful and longer-lasting than just about all of them.
Unlike a lot of maintenance products, Joker 440 doesn't contain PTFE which – though useful – is toxic and unkind to composites and seals. It also impairs electrical connectivity. The 'smart straw' helps ensure precise delivery, too. It's thicker than products such as GT85, and closer to the Tru Tension Maintenance Spray in consistency.
It lingers longer and, for me, seems more efficient when it comes to tackling stubborn contact points like seat posts, threaded bottom brackets and quill stems.
Several wet weeks and the odd waterlogged road later, I'm pleased to report there's a solid film still clinging to the rust-prone components I treated with it. No hint of tarnish, or loss of connectivity with the electricals either. In comparable conditions, I would've been into a third helping of GT85 to achieve similar results – at least on electroplated surfaces, anyway.
It lasts well even after several sudsy bucket washes, and lord knows I like my sudsy bucket wash narratives. That said, WD40 is better if you're simply flushing out drowned battery contacts and the like.
It works well on cleat mechanisms, locks and cables too, keeping movements and engagements reliable and slick.
Being thicker it's slower acting than some, but I found I needed less of it to encourage stubborn components to separate, and compared to WD40 and PTFE-infused blends, Joker 440 is palpably more effective. Three liberal blasts, left for 60 seconds apiece were sufficient to liberate a weathered Ti track sprocket and an old-school freewheel.
The lack of anything obviously harmful to rubber and composites means it's also safe for suspension linkages. It did an excellent job of silencing a squeaky sprung/elastomer unit, for instance, and it remained quiet even a very soggy fortnight later.
£14.99 for 500ml is steep. Tru-Tension Maintenance Spray is £8 for 500ml, while Juice Lubes JL69 is another bike-specific blend I'm fond of and £5.99 for 400ml. Then of course, there's WD-40 Multi-Use, which is £5.99 for 450ml.
Joker 440 is long-lasting and closer to being a penetrant/protectant than other multi-purpose maintenance sprays, and while it's undoubtedly expensive it's thick enough that a little goes a long way (and stays there a long time). If that's what you're after, rather than just something for flushing out cables and electrics, it's great stuff.
Thick, efficient and very effective as a protectant, but pretty expensive with it

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Motorex says "Fully synthetic, universal lubricating and corrosion protection spray. Leaves behind a highly effective protective film. Creeps under water protects against corrosion, takes effect dielectrically and cleans and maintains metals and plastics."
Tell us some more about the technical aspects of the product?
* eliminates squeaking
* protects against corrosion
* repels water
Does much the same thing as a wealth of other 'workshop in a can' aerosols, but the seemingly thicker blend is more effective at loosening rusted/stubborn components, including seat posts, stems and so on. The protectant qualities also seem more robust than WD40 and similar products.
The protectant film seems very durable.
The can is expensive, but a little seems to go a long way, and it works very fast too.
Tell us how the product performed overall when used for its designed purpose
Very well. It seems a richer, longer-lasting blend than most similar sprays, and works faster when freeing stuck components. The lack of Teflon is also nice, which means it's safe around seals and other rubbery components. It won't interfere with electrical components either.
Tell us what you particularly liked about the product
Long-lasting and particularly effective.
