Yeah, Felix thats a good point. "life" needs to consider that altering the bike in any way will negate the legality of the Shineray GY7. Even something as simple as changing the paint on a vehicle in China actually makes a once legal vehicle, illegal. I kid you not, I know several bikers who have had to repaint their bikes back to the original paint colour as they were first licensed.
