Some users in order to fuel, downhill (especially long slope) when in neutral or the clutch catch, only brake (brake after mainly rely on) to control the speed. Here we were to analyze the pros and cons of this method of operation, allowing users to understand the harm this method of operation, to master the correct method of operation. 1,  cub motorcycle manufacturer to make the rear wheel hub rim color: brake to control the speed after prolonged use, bound to the rear wheel rim temperature is too high, the temperature exceeds the range, make the material annealed, color, strength reduction, as well as long-term use of dangerous breakage.
2, increasing maintenance costs for parts, and there are security risks: rear wheel rim temperature is too high, easy to make the rear wheel rim bearing early damage caused by abnormal wear and rear swing, handling worse; rear wheel rim temperature is too high will make the friction plate high temperature failure, reducing the braking effect, accelerating friction plate, brake disc wear. Above, not only increases the cost of the maintenance user for parts, there is a great security risk.
