High Pressure Radiator Cap with Temperature Gauge for Honda CRF450R

This 1.8 Bar high pressure radiator cap with temperature gauge helps monitor coolant temperature and maintain proper system pressure on your dirt bike.

Overview

The high pressure radiator cap with temperature gauge is a direct-fit cooling system component that raises the boiling point of your coolant while giving you a live temperature readout at the cap. Built to 1.8 Bar pressure, it helps prevent boil-over during hard riding and lets you spot overheating before it causes damage. Ideal for riders who demand reliability from their CRF450R.

Good To Know

Q: Will this cap fit my CRF450R? A: It is designed for the CRF450R and CRF450RX, but confirm your model year and radiator neck size before ordering.

Q: Does a higher pressure cap cause cooling problems? A: A 1.8 Bar cap raises the boiling point, but it should be matched to your cooling system condition and not used to mask an existing overheating issue.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
