Motorcycles do have radiator guards available as aftermarket accessories, and some motorcycle models come with built-in radiator guards or protective grilles. However, not all motorcycles have them as standard equipment for several reasons:
Cost: Including a radiator guard as standard equipment would increase the manufacturing cost of the motorcycle. Manufacturers often prioritize keeping the initial purchase price of the motorcycle affordable for consumers, and radiator guards may be considered optional accessories.
Design and Aesthetics: Motorcycle manufacturers pay careful attention to the overall design and aesthetics of their bikes. Adding a radiator guard may disrupt the intended visual appeal or alter the bike's appearance. Some manufacturers prefer to leave the decision of installing a radiator guard to the rider's discretion.
Riding Conditions and Intended Use: The need for a radiator guard can vary depending on the type of motorcycle and its intended use. Motorcycles designed for off-road or adventure riding, where they are more likely to encounter debris or rocks, may have more robust radiator protection as they are expected to face more demanding conditions. On the other hand, street motorcycles primarily used for commuting or touring may not require the same level of radiator protection.
Customization and Personal Preference: Many motorcycle riders enjoy customizing their bikes according to their preferences. Radiator guards can be easily added as aftermarket accessories, allowing riders to choose the type, style, and level of protection that suits their needs.
It's important to note that protecting the radiator from damage caused by debris, stones, or other objects is crucial for maintaining optimal cooling and preventing overheating. Riders who are concerned about radiator damage can consider installing a suitable radiator guard as an additional protective measure.
