Hello guys,

long story short, I bought a 15 450 KXF last year and only rode it 20 hours.
Bike is great but I have never been confortable with the fork, it's a mess to tune before, after, between the motos. angry

I ride 5-6 times a year, I cannot spend 20 minutes at the track to tune these forks before every ride...

I have found 2010 & 2013 250 KXF forks for a good price on French Craiglist.
Which one to buy ? 10 or 13 ? Do they fit in my triple clamps ?

Of course, I'll make them serviced and probably revalved and springed for my weight and "speed"...

Thanks a lot

Find a 2009-2012 KXF450 fork and live happy.

Thank you for your reply mx317

Actually I found only 250 KXF forks to buy...
Are they the same compared to the 450 ?

I believe the 250s have showa forks and the 450s have kyb. Also the spring rates and valving are different. Im sure it would be on the soft side. Would be worth getting a revalve for sure

I am about 95% sure they will bolt on also (depends on year). I would contact a company that makes triple clamps and see if they would give you upper tube sizes. You might measure someone's 250 forks and compare. Both are Showa, but the 250 is 48mm SFF spring fork and the 450 is 49mm TAC. The size is the lower tubes which doesn't matter as far as bolting on.

I can have these for 150 bucks.
They definitively look like 2009 forks since lower tube are black and adjuster silver, (compression adjusters turned blue in 2010).
Any recommendation regarding these ? Buy or not ?

I have a complete A kit for that bike , dual spring fork with clamps. I ran it on my 16 because I hated the TAC fork. Let me know if you're interested.

Thanks dmm698 for the offer but I live in Europe and I am afraid that the price for your A KITmight be too high...

I have 09 kx250f and 450. Yes those forks are good

you will be better of finding 450 fork(any year) as they will bolt right in.
250 fork from 2013 on will bolt in. Anything before that will require the correct triple clamp.

Thank you Radfonz, I was about to pull the trigger on the 250 KXF 2009 forks...shocked

Are the 2013 SFF spring forks good ? I have found some as well.
Thanks

How are the forks set up, Spring rate and rider skill and weight?

Don’t piss off the old people - the older they get the less “life in prison” is a deterrent for them!

PC swapped out 0.48 for 0.49's when I had them set it up originally. They're setup for 180 pound Moto, B rider. They work really well.
