โซ่ DID ER Series Chain 415ERZ Gold เป็นโซ่ทีเบาและแข็งแรงมาก ถูกใช้ในรถแข่งอย่าง Moto 3 จึงมีราคาค่อนข้างสูง แต่เมื่อเทียบราคากับคุณภาพแล้วนั้น คุ้มค่ามากๆ The chain is very light and strong. Used in racing cars such as the Moto 3 is quite expensive. But when compared with the quality is very good.(translated by Google Translator)
I used it with ConversionSprocket of 415 Size used for NSR 50.
If you are doing Race or who is riding everyday, you can see the difference clearly from the change from 420.
Regarding durability, it is enough if you take a street ride.
SPSpec of NSR 250. Machine also has about 415 Size Conversion kit - - -
However, it is certain that the elongation is earlier than 420 w
I use it for Mini bike's for Race.
I use it from 415ER of the previous generation, but I feel that it became ERZ and became strong against twist.
It seems that Joint's Clip was also enhanced.
After using Race we will use it for the city ride Mini bike, but the fuel consumption has improved about 5% compared to the 420 Size Chain.
