Sure, sometimes it's nice to see that your bike has had fun too. Mud, spatters, dust, it can take it. On the other hand, good and proper maintenance of the motorcycle is recommended. Also on the outside.
Motorcycles deserve a healthy dose of respect and that translates in part into how they look. Keep them 'spic and span', as they say. Tidy, neat, keep their metal skin shiny. You can call it what you want, but a clean motorcycle certainly gives you added satisfaction.
We have the products that make this job a lot easier. Don't use some all-purpose kitchen cleaner on your expensive bike. The right products will make the whole process not only easier, but also a lot more meaningful.
