KEMIMOTO 420D Heavy Duty Waterproof Motorcycle Cover with Side/Top Box Compatibility
Product description
What it is
The KEMIMOTO 420D Heavy Duty Waterproof Motorcycle Cover is designed to guard adventure, sport, and touring bikes when they’re parked outdoors. It’s built to cover bikes with saddlebags or side/top boxes and aims to shield against rain, sun, dust, and bird droppings while staying secure in windy conditions.
Who it fits

On paper, this cover targets a broad range of bikes including popular adventure and touring models. If your setup includes top cases, saddlebags, or side boxes, this cover is positioned to fit within a fairly wide footprint (length 94.48 in, height 62.99 in, width 47.24 in).
What stands out in terms of structure
The shell uses heavy-duty 420D Oxford fabric with a waterproof rating of 2000 mmH₂O and strong UV protection (about 99%). Reinforced seams and windproof buckles are designed to keep the cover in place during gusty winds. A built-in lock-hole at the bottom adds a theft deterrent by allowing you to lock the cover to the bike or frame.



Where it adds value in use
Breathability is addressed with four breathable holes on each side of the handlebars, helping reduce moisture buildup under the cover. Reflective strips improve visibility in low light, aiding in outdoor storage scenarios.
Pros and what to consider

On the plus side, the combination of high waterproofing, windproof design, and a lockable bottom hole provides a practical all-season option for outdoor storage. The 420D fabric suggests durability and elasticity to handle long-term use. A potential limitation is that real-world fit may vary depending on your bike’s exact dimensions and auxiliary gear like larger top boxes or unusual saddlebags, if you’re near the edges of the stated footprint, you might want to verify fitment before relying on it in extreme conditions.
Who it’s for
If you regularly park outside and want a single cover that accommodates bikes with additional luggage (side/top boxes), this model could be a sensible balance of protection and practicality for daily use, road trips, or longer outdoor storage sessions.



Who should think twice
It may not be ideal if you need a snug, form-fitting cover for a compact bike with little extra baggage, or if you require a cover with a dedicated, custom fit for a very specific model not covered by the listed compatibility.
When it makes sense to buy

When you need a weatherproof, wind-resistant solution that can cover a bike with boxes attached and you value the lock-hole feature for added security in outdoor parking.
What to check before buying
- Confirm your bike’s overall footprint aligns with the 94.48 in × 62.99 in × 47.24 in range.
- Consider whether the lock-hole fits your security setup and rack configuration.
- Think about climate needs: 2000 mmH₂O waterproofing is strong, but extremely heavy rain or prolonged exposure may still require periodic inspection.



Practical usage scenario
Imagine you’ve parked your adventure bike at an outdoor lot after a long ride. You roll this cover over quickly, secure it with a small cable through the lock-hole, and the wind doesn’t threaten it thanks to reinforced seams and buckles. In the morning, you find a dry, dust-free bike with preserved paint from sun exposure thanks to UV protection.
Quick comparison in mind
If you prioritize a rugged out-of-the-box all-weather solution for bikes with luggage, this cover sits between basic rain guards and ultra-heavy duty auction-style options. It’s a sensible middle ground for riders who want weather protection plus security features without committing to a highly specialized, model-specific cover.
FAQ (based on available data)
- Q: Will it fit my bike if I have a large top box? A: It’s designed to cover bikes with saddlebags or top/sides boxes, but actual fit depends on your exact dimensions.
- Q: Is it breathable enough to avoid moisture buildup? A: Yes, it includes four breathable holes on each side of the handlebars to promote air circulation.
- Q: Does the cover deter theft? A: The lock-hole design allows you to secure the cover to the bike, adding a level of deterrence, though it doesn’t replace a locked garage.
