ISO KX450 KYB Forks

does this mean you have the original showa forks + shock from the 450? if so would you be interested in parting with them.
i have to think about it but i have a set of kyb forks and shock out of a 2021 kx250 which fits into ur model 450

your showa production fork is and has been essentially showa a kit since 2019, sans a few minor differences.

Well it has a lot to do with what you're asking. You're chasing a set of KYB kit style forks, because you think then your bike(s) will feel similar. My point was the showa fork can be made to feel very similar to the KYB fork on your SR depending on what the internals are, and it would probably save you some money over buying another set of forks and then having to pay to have them setup.

So with that being said, contact member Jbulz on here. He owns Corsa Technica. He already has the 19+ KX450 chassis modeled, and all of the showa internals modeled. If you are capable of providing some measurements of your SR forks internals, he can most likely have them feel identical. Or provide the two sets of forks and receive them back. Thats up to you guys to figure out if you reach out to him. This is simulation backed, not somebody slinging shims with what they think.

My current kx450 has some settings from this simulation model and I can attest to it being the best revalve i've ever ridden. My yz250 with showa works components also has settings through a yz250 model he developed and it works good as well.
