There are several reasons why not all motorcycles come with center stands:
Cost: Including a center stand adds to the manufacturing cost of a motorcycle. Manufacturers may choose to omit it on lower-priced models to keep the overall cost of the motorcycle more affordable.
Weight and Complexity: Center stands add weight and complexity to a motorcycle. For lightweight or performance-oriented motorcycles, reducing weight is often a priority to improve handling and overall performance. Center stands may be left out to save weight and keep the motorcycle more agile.
Design Constraints: Some motorcycle designs, such as sport bikes or cruisers with low-slung frames, may not allow sufficient space or clearance for a center stand. Designers prioritize the overall aesthetics and functionality of the motorcycle, and a center stand may not fit within the design parameters.
Rider Preference: Some riders prefer not to use a center stand and instead rely on side stands or other methods for parking their motorcycles. Including a center stand on every motorcycle may be seen as unnecessary by certain riders, and manufacturers may choose to offer it as an optional accessory instead.
Aftermarket Availability: Even if a motorcycle doesn't come with a center stand, aftermarket options are often available for purchase. Riders who desire a center stand can explore aftermarket options that are compatible with their specific motorcycle model.
It's important to note that while not all motorcycles come with center stands, many touring, adventure, and dual-sport motorcycles do come equipped with them due to their practicality for long-distance riding, maintenance, and stability when parked.
