Zongshen RX3 Update Calipers & Fork

damian7j · 01-31-2018, 07:35 PM

I'd like to know if there is some kind of upgrade for the calipers and suspension for this bike.
I have de RX3 here in Mexico and it is almost impossible to get parts and accesories.

SpudRider posted a list of break pads that were totally compatible for my bike, and I want to know if there is a chance to upgrade the calipers and the front inverted fork.

Thanks a lot.

In USA we do not have any known upgrade for front suspension or brake caliper.

CSC does sell a larger diameter front brake disc (rotor) that helps for more powerful stopping. I do not know if they can send to you. Sorry.

I changed the fork fluid in my RX3's and it made a huge difference. "Modern Japanese"? No....but far better than they were with the stock stuff in them.

I'll have to check tonight but I believe it was 10w Bel Ray.
I know that fork fluid threads can be like oil threads (fork oil vs ATF) but since my Moto-X days, I've always just had really good results with Bel Ray so it's a habit.

EDIT:Confirmed! 10W Bel Ray.

If you are a big person, use 10W fork oil. ATF feels more like 7W and is a bit light for a big rider in my opinion. Might be perfect for a light weight rider. Bel Ray is good stuff. Either is better than stock.

Thank you so much, guys. I tried the forks with the new oil and worked great.

New issue is that i can't find a compatible oil filter for my bike.
¿Any suggestions?

Glad it worked out for you!
The CSC oil filters are a tad pricey but I usually order a six pack if I order something else. They toss them in the box and save shipping.
I'd like a pair of those cleanable ones though.........

Reusable filters save a lot of money over time. Anyone know where to get them? Through APJ? I've no experience with the Chinese marketeers, but I'd like to learn.

EDIT: CSC updated the RX3 forks to add adjustability beginning with the 2016 model year. If you have a 2015 those new forks would be an upgrade, I guess.

Look on aliexpress or alibaba and search for NC250 oil filter. You'll see both paper filter and metal screen filters. Some APJ who has a bike that uses the same NC250 engine as the RX3 comes with the metal filter. So if getting filters is difficult you could get a metal one. Wash it between oil changes and use it forever.
