Hey guys quick question...my 15 CRF450r forks are not cooperating at all and I'm interested in buying a set of spring forks from an older model...I found a set off of an 09 CRF250r I know that they are 47mm but they come with a triple clamp. My question is if I use the triple clamp will this setup mount right up? I know that I will have to get a caliper relocating bracket but other than that should everything fit? Also can I still run the 13-16 front fender and number plate?

Thanks
Mike

I checked a few aftermarket brands, and they showed different part numbers for these years and show that the clamps aren't interchangeable. Also, I believe those forks are shorter in total length than your current forks.

I would recommend finding a set of 48mm KYB AOSS forks from a Honda CRF450R and using those. They would work with your current clamps, but still might be 5mms shorter than your current forks. I'd have to go check the specs again...

Are 15 crf forks same as 13 crf 450? I have forks for all generations both 250 and 450s I would trade??

I put 2014 CRF250 Showa spring forks on my 13 CRF450. Direct bolt up. Works phenomenal! I couldn't be happier smile

I didn't think they would be interchangeable just because the 09 forks are 47mm and my 15 forks are 48mm...I can't find and forks from a newer bike that doesn't cost less than $1200...the steering stem should be the same though shouldn't it?

The 13's have the psf1 forks and the 15 has the psf2 forks...they are pretty similar but there are some differences.

I was told by factory connection to go with the 2013 Honda crf250 forks on my 2015 crf450. They swapped right out and I've been happy 30 hours later. Real nice upgrade although the air forks were good enough

2009 crf450 are 48 mm kyb aoss they will absolutely bolt right up and 2009-16 450 share the same 20mm clamps 2010-16 250 are also the same clamps

I put 2012 crf 250 on mine love love them.

Unfortunately I could only find 09 CRF250r forks but the good thing is that they came with a triple clamp so I can use that triple clamp with those forks...I wish I could've found some 48mm for cheap but I couldn't find anything. What kind of forks are on the 09 crf250r? Are they the AOSS? Or are they the same forks that were on the 2007 CRF450r?

What are the chances I could get you to measure:

Top/bottom clamp area size
Top of fork to center of axle
fork lug offset

for the various generations and models?!?

I'm having trouble finding that info anywhere.

THANKS!

I can definitely do that for you just tell me exactly what your looking for with the clamp measurements. I don't know how to figure out the fork lug offset.

Sweet. Center line of fork tube to center of axle for the lug offset. Should be between 32mm-38ish mm. Hopin for 35 smile

My 2006 crf 250 showa 47mm dual cartridge fork got 38mm fork lug offset.

If I didn't fuck up the measurement.. laughing

Thanks! I've seen that measurement somewhere before for that generation so I think you got it right. Looking at my forks last night and it doesn't seem like an easy thing to measure accurately.

Could you confirm you measured the distance perpendicular to the fork leg, and not parallel with the ground, like here?

I ask because I wasn't sure which was correct myself until just now!

Thanks

Can't you just throw in some Ohlin internals? By all accounts they work pretty sweet.

I measured the axle offset for every CRF I could find at Hangtown today (there were only 3!).

'16 CRF450R 32mm
'15 CRF250R 32mm
'09 CRF450R 35mm

Can we assume the 35mm applies to '09-'12 (450s)?

The 09 - 12 450 forks will bolt right on. I had a 13 and ran 2010 forks. Which I still have by the way. hint hint.

Also as another poster said, the 10-14 250F forks will bolt right up. The 13 - 14 forks are superior though. I personally think the 13-14 CRF250R Showa's are the best production forks made. I'm willing to bet the the 17's will return to these (if the rumors are true)
