Waterproof Motorcycle Cover for Honda Grom MSX125/Navi/Monkey

In this review the Waterproof Motorcycle Cover for Honda GROM MSX125, Navi, Monkey and compatible 2022 Benelli 135 / 2023 Grom is evaluated for everyday outdoor protection. The bottom line: this cover is best for riders who need a compact, easy-to-store solution that delivers reliable waterproof and UV protection without damaging finishes. It stands out for its reflective strips and exhaust heat insulation, making it a practical choice when secure, visible overnight storage is the priority rather than a heavy-duty, multi-year shelter.

Key Features

• Fitment: Designed to fit GROM MSX125, Navi, Monkey and compatible Benelli/Grom models, it offers a tailored fit when you check your bike length before purchase.
• Waterproof PU Coating: The black PU coating repels rain and provides UV protection to help prevent cracking and fading of leather and plastic parts.
• Ventilation: Two air vent holes reduce trapped moisture under the cover, helping to limit condensation and mildew on the bike finish.
• Night Visibility: Two full green reflective strips increase visibility and help reduce collision risk during low-light storage or roadside stops.
• Wind Security: Three windproof buckles, two long straps and elastic hems front and rear keep the cover snug and resistant to lift in windy conditions.
• Exhaust Protection: A heat insulation cotton layer at the exhaust area prevents the cover from melting when put on after the engine has cooled sufficiently.

Who It's For

This cover is well suited to owners of small-displacement bikes like the Honda GROM MSX125, Navi and Monkey or the listed Benelli 135 who park outdoors and want all-weather protection that is light and packable. Commuters, apartment dwellers and riders who need fast on/off coverage and a compact storage bag will find the balance of features useful.

It is less appropriate for owners who require a heavy-duty, multi-year abrasion- and theft-resistant cover or for those who need full tire coverage on oversized custom setups; some users have reported mixed durability and coverage limitations on larger tyre profiles, and the included lock holes require separate locks for anti-theft security.

Pros & Cons

Pros

• Good waterproof performance and UV protection from the PU coating keeps paint and plastics safer in sun and rain.
• Reflective strips and FRONT sign improve nighttime visibility and make the bike easier to spot.
• Vent holes and heat-insulated exhaust panel reduce moisture buildup and protect the cover from hot pipes when used correctly.
• Compact storage bag and relatively light 300D oxford build make the cover easy to stow and handle.

Cons

• Mixed reports on long-term durability mean heavy daily use or very exposed coastal conditions may shorten the cover lifespan.
• Coverage and strap length can be borderline for some tire and accessory setups, so measuring the bike is recommended before purchase.
