Zongshen RX3 Update Calipers & Fork
 

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.

2lz ,what did you replace oil with weight wise? ATF or 10wt or ? rj

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?

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.

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.
