49mm Forks Suzuki, Honda, Kawasaki

CharlieJ125
Hey evryone, I have a question regarding the OEM 49mm Showa forks that come stock on the:

2018- Current Suzuki RMZ450
2017- Current Honda CRF450R
2019- Current Kawasaki KX450

Does anyone know if the top tubes are the same between the 3 bikes? I know the anodizing colour is different between the bikes, I am wondering about the clamping dimensions.

I have a 2022 CRF with a damaged top tube and they are on back order at the moment. I am considering ordering a set of Suzuki top tubes to replace and have the gold anodizing.

Thanks in advance!

The Suzuki ano wears pretty quickly.

Suzuki tubes have a 55mm upper clamp and the Honda has a 54mm upper clamp diameter. Lower clamp diameter is the same though. You might be able to use kawi ones but not sure on their top clamp diameter. But those tubes do have the showa dimplush inner coatings

No, Suzuki is 560mm. I think the Honda ones are 572-3 I can’t remember off hand. Total fork length is the same but you’ll have different overlap between the three options

Suzuki had 49mm tubes back in 1999?

Did you ever figure this out? I’m wondering if Honda outer tubes will fit on the Kawi showas.

Here’s a picture of a 2023 KX450 fork on a RMZ450. The upper clamp surface diameter is 1mm smaller and will not work. IMG 2491.jpeg?VersionId=SL .YPP7loK DrWl6Yf
