The speed limit for a Honda Hornet, or any motorcycle for that matter, is not determined by the first service. The first service of a motorcycle typically involves basic maintenance tasks such as an oil change, checking and adjusting components, and inspecting the overall condition of the bike.
The speed limit for a motorcycle is typically determined by legal regulations and road conditions. In most countries, speed limits are set by local authorities and can vary depending on the type of road (highway, city streets, etc.) and other factors. It's important to follow the posted speed limits and adhere to local traffic laws for your safety and the safety of others.
It's worth noting that motorcycles, including the Honda Hornet, have different speed capabilities depending on their engine size, design, and overall performance characteristics. The Honda Hornet 160R, for example, is known for its sporty nature and can achieve speeds in line with the regulations and conditions in which you are riding.
Always prioritize safety, obey traffic laws, and ride within your comfort zone and the limits of your motorcycle.
