I bought these for my DRZ400SM. Ideal for direct installation. They appear to be well made and can withstand high temperatures and higher pressures. No more worrying about my hose bursting! Another review mentioned that the overflow hose clamps were not included and the original clamps do not fit. Both are true; However, you don't need to use clamps on the overflow hose. The hose is not pressurized and is designed to prevent accidental overfilling or boiling over etc.
