2003 Honda CRF450R Radiator Cap

Recommended Posts

Can someone tell me the recommended radiator cap for CRF 450r.  It as a 1.6 bar cap on it now.  I believe it is the OEM cap that came with the bike but I have no idea for sure since I bought it used.  It weeps a bit to much for me on a long ride.

stock is a 1.1bar.. i added 1.6bar to both my 04 and 08 for woods riding/racing. So if your 1.6bar is weeping, it's getting wicked hot.

Okay, thanks.  We do a lot of woods and trail riding so I will get a new 1.6.  The bike was setting for over 5 years before I purchased it.  I hope it's just age.

Yes, don't make the mistake I did; replace your radiator cap every season, if it's a 1.6!

 

Otherwise.....

 

My cap did not release, and instead it allowed the radiator to expand and crack in several places. No plum of steam, no smell, as it leaked out so slowly and quietly (YZ).

Did not notice the heat till I was 20 miles from the truck and out of water.....
