*The installation of the DY Racing Center Spring requires special tools and expertise, so please have it installed by someone who is familiar with the maintenance work, such as a shop that handles WirusWin products. *There may be changes in product specifications due to the manufacturer's reasons.
DYRacing is a famous manufacturer established as a high-spec parts manufacturer in Taiwan, and has the No.1 share in the Taiwanese racing market, which is used by many riders. The spring rate is strengthened by 15% compared to the stock type. Eliminates the lack of torque that occurs when an third party's exhaust is installed. Especially when used with the WirusWin exhaust, it has an outstanding effect. The effect is great even with a stock exhaust, and it is recommended for stock engines! It accelerates smoothly from zero start to maximum speed. There is no unevenness in the rpm drop, and the body reacts quickly when you want to move forward with fine accelerator operation, so it is very effective for passing through town. If you replace the Hyper Weight Roller Kit at the same time, it will be more effective.
