$24 ebay fork preload adjuster review

I'm a skeptic by nature, but $24 is a small price to pay to find out, so I bought a pair of chinese fork preload adjusters from ebay and installed them today. I also ordered some shorty levers ($20) that coincidentally arrived today so I installed them too.

So, are the cheapo ebay chinese products worth it? I'm happy to say that sometimes you get more than you expect, and in this case I got much better products than I would've ever imagined.

I made a video review of the fork preload adjusters for you guys. See it here https://www.youtube.com/watch?v=kzyY01S_DoI

I think i know the ones your talking about.
You'll need to provide your own o-ring, but if your careful removing/installing your should be able to get away with reusing the original one.
Check clearances between the bar and the space tube, as you are likely to also need an appropriately sized washer.
When fitting them, place some plastic around it before putting your tool on it, as the anodizing is more like spray on paint and comes off waaay to easily.
Other than those items, functionality can't complain, it works as intended and construction is solid for the purpose.

What makes

Good Video.

I also have the Chinese, pre-load adjusters and they fundamentally do exactly the same thing as the more well known brands. So I agree, Why pay more.

Whilst they make a huge difference over the stock set up you might start experience is a jolting feeling when hitting sharp edge bump but you can fix that by increasing your fork oil viscosity to 15 or 20w. You could also install emulators for more adjustability.

You are around the same weight as me and at 90KG and you have cranked down the pre-load adjusters to just about to the max meaning these fork springs are probably too soft for you but you would need to confirm this when setting your sag.

Question. Do you still have the stock rear shock and if so has it highlighted the Pogo effect in the rear end? Not sure if you have the ABS model or not but upgrading the rear shock will compliment the front enormously.

Well done.

The adjusters I got are the "M-Factory" ones. They came with O-rings and there's no need for a washer. The metal bushing at the bottom is not cheap thin steel like some of the ebay adjusters. The bushing is CNC T-6 aluminum and is much thicker than the ones that have the steel bushing. The anodized finish is better than I expected, but you're right, you should certainly protect it when adjusting. I just placed a handkerchief over them before putting the 14mm wrench on them and that worked well.

I should mention that I went ahead and turned mine out anothother turn and I feel like it's just right now. I'm not getting the jolting feeling you mentioned. In fact it's quite the opposite. I've notice that when going over sharp edges or rough spots on the road the bike handles it much better. On the stock setup it seemed bouncy. The reactive recoil was too slow on the stock for sure. I find that hard shifting and hard stops have much less rise and dive and my acceleration and stops are much smoother feeling now. I absolutely hated the dive on hard stops. Seriously, HATED it. Now the dive is minimal and recoils immediately. I do still have the stock rear shock. I had already set my rear shock at 6 and I find that 6 is still quite good for my weight and the sag is right on. I'm not experiencing the "pogo" effect you mentioned at all (Mine isn't ABS and I'll mention that I don't prefer ABS. I want to be able to lock up if I need to). I feel like the rear shock is fine and I'm not considering changing it atm. I had considered changing the fork oil to 15w but I'm feeling very good about how it feels right now so I don't think I will at this point, but it is good advice.

On the cheapo eBay units, do they add preload from the get go even with them backed off? Or is the starting point the same as the factory non adjustable caps?

Okay, I can't post the link due to being a new member and not having any previous posts......but I found the M-factory pre-load adjusters by searching for their ebay store, and then typing in "preload" to search their store. They have adjusters that say they fit the CBR500 13-14, for $26.80 USD. Hope this helps.

**They actually say they fit 14-15, my mistake....not that it makes any difference since the '13 is the same.
