So I’m picking up a leftover, but still brand new FC 450 this week from the dealer and I was hoping to get some help on a couple of questions on the forks.

I have a 2015 fc450 that has Ohlins RFX drop in spring kit in the WP cartridges. I plan on selling the bike. The forks have less than 30 total hours and recently were completely revalved.

Should/can I:
1. Put those forks on the 2019? Would they fit?
2. If so could the 2019 AERs fit on the 2015 to swap and sell it?
3. Should I just sell the 2015 with the ohlins on them and pick up a new set of RXF or CVs?
4. Should I just get the 2019 WP air forks worked on and improved?

Thanks in advance for the feedback,

-Your older forks will fit but will be shorter then the AER and have to be adjusted accordingly height wise

-The AER will fit on the 15 but will be longer and need to

-The axle diameters will be the same

-19 AER forks are pretty nice but like any air fork have a break in period and tuning. Pressure, oil height, valving all will make for a great setup... I found spring forks to be easier starting point but you also have to pay upfront...

Would the spring forks off my 2015 feel much different than if I swapped out the internals on the 2019 aer set once I had the fork height sorted out?

You can’t directly swap them because the bottom inside of the lug is different on the AER.

You can't swap out the internals. The AER fork lugs have a smaller diameter for the cartilage then the 4cs forks. You would have to swap lugs also. The forks will bolt right up, the cartridges won't...

I think I worded that wrong. My question was - Would there be a noticeable difference between me putting the forks from my older bike on the 2019 versus if I got the new ohlins kit for the 2019 forks.

Basically, have there been drastic enough improvements in the last 4 years to warrant not using the expensive set of spring forks that I already have and getting a new ohlins or other company drop in kit for the 2019 forks?

Sorry for the confusion. Just trying to figure out the best path to take.

Thanks!

If you stay with HQV or KTM for a while you could buy a CV fork and use it on several bikes. I have (a very good) AER, standart spring forks from 2015 and 2018 CV - the springforks are better than AER but the CV has much more reserve to handle overjumping and high speed bumps. So I would just buy a used CV and put it on this and the next bike.
