Royal Enfield Navy Water-Resistant Bike Cover (Part No. 1990643) — Genuine RE Accessory for All Royal Enfield Models

Protect your Royal Enfield year-round with the Genuine Royal Enfield Navy Water-Resistant Bike Cover (Part No. 1990643). This factory-approved accessory is tailored to shield your bike from rain, dust, UV, and grime while folded neatly in its storage pocket. According to the Bike-Parts Royal Enfield catalog, this is a certified genuine spare — identical in materials and branding to what is offered by RE dealers.

The cover is made of premium water-resistant fabric with reinforced seams and elastic edges for a snug fit. Many retailer listings show it marketed as “fits all RE models” (Standard, Classic, Electra, Thunderbird, Bullet, Meteor, etc.). 

It folds into a compact zippered pouch, making storage convenient. Having this cover means you can leave your bike outdoors with greater peace of mind — no more worry about sudden showers, bird droppings, or harsh sun damage. The cover also preserves paint, metal parts, and cosmetic finishes.

Installation is trivial — just drape and stretch the cover over the bike. The elasticized hem ensures it holds well even in windy conditions.

FAQs

Q1: Will it fit heavier / wide bikes like those with panniers or crash bars?
A1: It’s made to stretch reasonably. However, bikes with wide accessories may push the cover’s limits — best to measure fully installed width before ordering.

Q2: Is it fully waterproof or just water-resistant?
A2: It is described as water-resistant — it repels moisture and light rain, but in heavy downpour or sustained rain, some seepage is possible along seams. Use under shelter when possible.

Q3: Can I use it outdoors permanently?
A3: Yes, for temporary outdoor parking. But for long durations, especially in harsh sun or extreme weather, periodic removal & drying is recommended to avoid trapping moisture under the cover.

Q4: Will it scratch the paint when putting on/taking off?
A4: The fabric is soft on the inside. Still, be cautious and avoid dragging over dirt or grit. Clean the bike before covering if possible.

Q5: Is it a genuine part from RE?
A5: Yes — the Bike-Parts Royal Enfield catalog lists 1990643 as a genuine spare part
