2002-2003 Honda CRF450R Service Manual


As some may or may not know, I am an avid mx’er (motocrosser) and currently own and run an offroad motorcycle and ATV web forum.

I often see requests for manuals, and over the years I’ve managed to buy and receive a few of them.

As of late, I’ve seen quite a few requests for older CRF450R manuals, and since that was my first bike, I just happen to have one, though I can no longer share it due to copyright laws and my desire to stay out of trouble.

So without further ramblings, here is more information:

Sorry — The free download of this manual is in violation of Honda’s Copyright laws and has been removed. You can purchase this manual online from Helm Inc.

Please do NOT email me for a copy of this manual. I will not be able to fulfill your request.

    Hi mx-guy,

    I just wanted to thank you for providing this service manual as a free download. I am a german living in Chiang Mai, Thailand and just bought a CRF 450 It needed some work impossible to do without a service manual which is very difficult/expensive to get in Thailand. Thanks to you I am off to our beautiful trails and tracks with a much better performing bike.

    I’m just glad to help, and glad you are going to be able to put it to good use.
    Mmmm Thailand has got to be a lot of fun on a bike.

    Thank you, thank you! I only I had found this site before I ordered a Haynes manual from Amazon. Now I can dig into my new (new to me) toy.

    Keep the rubber side down

    MxGuy, thanks a bunch – you are the only site with this download available i could find. My buddy swamped his cr last year end of season and siezed the piston, he just got laid off and is about to have a child. So – you guessed it, time to revive the Ol’ girl and go for a ride !! It’s an 07′ but like you said, not much other than the plastic has changed. this saved a good chunk of change for him as without a job, money needs to be saved for parts !!

    thanks again – great help.
