CRF's Only Forums

Hi everyone,

Im new here on the forum, im using a Crf450r 2009-2012 engine and im from the Netherlands looking for help. I Recently bought a used Hotcams that is in mint condition the previous owner did not know what stage it was, on the Cam it says: Hotcams SF124 2799.
Maybe anyone on this forum knows what type it is by the Numbers ?

I have send a e-mail to Hotcams but whitout respons, local shop did not had the answer either.

My guess it is a stage 2 but since it came with cases , 480 barrel and other small parts it might be a stage 3..

Thanks!

Hi HondaRacingHolland and welcome to the site.

I tend to believe that is a casting number and not a part number as it doesn't look like a Hotcams part number. At least not what is used in Australia.

Is the number cast or stamped?

Welcome to the site !!

What you would be looking for is a number like

09 CRF450R
1123-1 (Stage 1)

1124-2 (Stage 2)

1125-3 (Stage 3)
..........................

10 450R ,11 450R , 12 450R
1259-1 (Stage 1)

1260-2 (Stage 2)

1175-3 (Stage 3)

Hi HondaRacingHolland and welcome to the site.

Is the number cast or stamped?

Seems like they used a laser to get the numbers in the Cam, those Numbers are the only Numbers, when im home i will make a picture

Here’s a video of the hotcam: https://youtube.com/shorts/dkln7WTu0yc?feature=share

Judging by the #124 and the following # beginning with 2 , I am going to say it is a Stage 2 , which would be HotCams part # 1124-2 , since yours is a 124 2799 , I would say that coincides with the part number area you are seeing ......

Thanks Jim that clears things up, now my following question.
In a previous post you Said the 1124-2 is for the 09’ Does it also fit the 2010/2011 models?

I am guessing that since there is a difference in Stage 1 , 2 , and 3 part # for 10 , 11 , 12 , I am thinking they changed the decompressor system on those years , as I seem to recall there being issues with it in 09 , and they also changed around the valve sizes ... so I am thinking they don't interchange , or at least not all the years , I am sure the heads will bolt on , but I would guess you would have to use all the components to match the given years , as the Honda Service Manual I have goes from 09-11 , but not 12 , so there must be at least a significant difference with it compared to the 09,10,11 ... but I am not positive .... HotCams would have the insight to those specifics , it seems All Balls Racing Group is in control of HotCams , so you might contact them directly for the specifics to that , as that is beyond my insight , and ask them if they do interchange and if so is anything special needed , as like I mentioned , Tower , etc. as there is usually a reason behind it https://www.allballsracinggroup.com/hot-cams
