Product Details

The Mishimoto MMTS-HON-05L is a low-temperature performance thermostat engineered specifically for 2005-2014 Honda TRX450R and TRX450ER sport ATVs. This performance thermostat opens at a lower temperature than the factory unit, allowing coolant to flow through the engine earlier and promoting reduced operating temperatures during aggressive riding conditions.

Key Features:

  • Lower activation temperature than OEM thermostat for improved cooling efficiency
  • Helps maintain optimal engine temperatures during demanding riding conditions
  • Direct-fit replacement for 2005-2014 Honda TRX450R and TRX450ER models
  • Precision-engineered construction for reliable performance
  • Ideal for racing applications, high-performance builds, and hot weather riding

By activating at a lower temperature, this Mishimoto performance thermostat helps prevent engine overheating during extended periods of high-RPM operation, trail riding, or competitive racing. The lower operating temperature can contribute to improved engine longevity and consistent performance, making it an excellent upgrade for riders who demand more from their Honda TRX450R or TRX450ER.

So far good

Shipment notification was sent from a third party and nowhere said it was affiliated with you so I wasn't exactly sure what was coming. Not a big deal, just slightly confusing.

Great site, easy order.

We will see if it is right.
