Wanted! A kit for honda Crf 250 2018

Budget?

I know of a brand new set for 17/18 450F - The forks interchange, just not sure on the shock...Can ML512 chime in regarding 450F to 250F fitment?

Does this kit happen to have aftermarket triple clamps? I'd be interested in clamps for an 18 450

Modern A-Kit is a direct fit on the 22mm offset 49mm clamp OE 17'/18' 450's; Much more convenient than sourcing triples like before

I don't think so. The clamping diameter on the 2018 CRF is the same clamping diameter the CRF450 has had since 09. Just the clamp offset has changed.

macz is right, my A-kit only fits in my 2018 250 if I change the top triple clamp

I'm not sure that's right. I've had all three of the most recent generations and I'm certain the 2011-2012 clamps were different than the 2013-2016. The 17-18 may be the same as previous though. That I'm not sure of. I just want the bling in all honesty haha

The 2011-12 have a different lower bearing than the 13-16 clamps. That's the only thing different. True A kit forks will not work on any stock CRF ckamps no matter what year.

I had called Ride Eng about this. Macz is right.

Nice, so... Are these not A kit or does this guy need clamps too? Ha I just want some clamps. I don't need the kit anyway. This poor guy (OP) is going to be so confused though.

Same goes with kawi oem 49mm forks. True akit forks are 1mm larger in diameter at the top clamp.

Mac and CS599 are correct, most A-Kit has 55mm upper clamp diameter; 1mm oversized over OE 49 setups. However, the new black (from ML’s tech-tip video) or kashima options (shown above) are 54mm and a direct fit onto latest generation CRF’s. My best guess would be that they’re more production based than before with Showa looking to compete with the easy to install Cone Valve competition.

I only have first hand experience with rmz stuff but it looks like someone did a tube swap on your kit, the new style A kits i have are 56 top and 59.7 lower, they don't fit in any oem clamp. You can retrofit them to oem 49mm upper tubes which might be the case with the picture above ( size and lack of positioning marks for the top clamp give it away) .

Picture to prove I'm not blowing smoke on those numbers

just bore the top clamp

A friend of mine just put a set of new a-kits straight from Showa on a bike. No clamps needed. The newest a-kit stuff fits in the stock 17-19 Honda clamps 100%. No tube swaps or anything. It will be the same with the new kxf, and I don't know for sure but I'd imagine the RMZ's.

He is correct with them competing with WP cone valve. The factory forks are still larger(I have a set on my 125 with a 58mm upper clamp area) but the customer spec A-kit is going this direction.

If you get them through pro circuit they may be larger like they have been forever though since they kinda do a hybrid of their own thing/what showa wants.

Check for kyb semi suspension works with oem clamps
New in Europe about 5000 euro

Showa is little better but is very expensive

They don’t make 58 uppers anymore, 56x59.7 for most bikes but I believe showa is utilizing stock fork sizes from here on out.

My opinion I have the kyb kit in my son bike forks come from 2012 crf 450 with 0,45 nm spring (67kilos rider )
OEM showa 49 is perfect same to factory kyb (kyb little better felling because have dlc tubes0
Showa shock need work
First I take race tech gold valve kit and works better before 15 days buy KYB
KYB shocks fantastic much better to showa
I you need something special send your forks for dlc and kashima and buy only shock KYB or showa kit a
Kyb in Europe have about 2200euro and showa about 3000

Not to hijack thread but is the 2012 Crf kyb forks same offset as 17/18

same offset only you need older break adapter 2004-2014 and is 6mm sorter to 2016+
