Hey dubSolo, I am at the point of installing my Kepspeed swingarm. I was curious if you could provide an update about the chain slider situation?

I really like the swingarm, but the chain slider seems somewhat marginal. When I look at my stock slider, I can see where the chain makes quite a bit of contact with it on the top and bottom. With that said, the stock slider also hangs off the inside of the swing arm following the chain line, but with the Kepspeed the chain largely clears the swingarm altogether.

Have you noticed any chain contact on the swingarm, top or bottom? I don’t want to beat up/chew up the swingarm unnecessarily.

I’m tempted to install the stock Honda slider, but it would be nice to not have to mess with it, if possible.

Using the stock slider was my initial idea but didn't want to manipulate kepspeed swingarm by drilling holes in it to use.

With that said If you figure an alternative Do It and Keep Me in the loop.

15tooth front sprocket Regardless of how loose or tight the chain this is going to happen. 16tooth makes less contact but still slaps and occasionally rides the slider.

After it chews through slider it's definitely going to slap and or ride the swingarm.

So definitely need a permanent solve without having to order a replacement slider from kepspeed.

If even possible...

Thanks for the quick response. You are awesome. That is exactly what I needed to know and see.

I think I’m going to look into mounting the stock slider and just be done with it. I considered having a local welder fill in the holes left behind from the Kepspeed slider. Since I have the polished aluminum version, I think I could polish up the filled in areas. My reasons would be to keep water and debris from infiltrating, but mostly for aesthetics. It may take me a little longer before I get the swing arm mounted, but I think it will be worth it.

I really like this swingarm, but they should have provided a better chain slider.

I made a small aluminum bracket for the brake side of the swingarm to provide a tab that the fender hugger fits over. The hole that Kepspeed drills is too far forward for the front L-bracket to fit into the fender hugger slot. I think they are all drilled that way.

I just noticed that your Kepspeed chain slider is screwed on. Mine is riveted on, which I think is stupid. Rivets make it more difficult to replace the slider, but I doubt you can get a replacement slider anyway.

Did you change yours from rivets to screws? If so, are the holes pretty small?

I’m wondering how easy it would be for a welder to fill them in.

Yes I used fatter self tapping stainless screws instead of riveting back on after attempting to use stock slider.

The holes are fairly small though, Be sure to post what you come up with so I can follow suit...

Oh wow, so did you test fit the stock slider to see how well it fits on the Kepspeed swingarm? If so, does it lay in place pretty well?

Best I can tell, the Kepspeed is a larger diameter at the round pivot section (where the needle bearings are). About 3.5 centimeters. The stock swingarm appears to be about 3 centimeters. That’s with me measuring while the stock swing arm is still on the bike, so it is hard to see for sure. I’m wondering how well the stock slider will wrap around the pivot part.

I’m not terribly worried about drilling a few new holes in the Kepspeed swingarm. The brake side has three holes drilled in it. If the swing arm fails, I doubt it would be the arm. More likely a weld would fail, I would think.

Yes, I will post whatever I do over in the Kepspeed thread. That way it will be the definitive thread for these swingarms. I will also post photos of my fender hugger mounting tab I made.

Thanks buddy, for all of the photos. That is super helpful.

The screw holes don’t bother me. It’s those larger holes for the rubber plug part of the slider, that would concern me. Those are fairly large.

One thing to remember is the Kepspeed arms are not one big hollow chamber I don’t believe. It has two cross sectional pieces inside the boxed arm. I’m sure it could handle some small holes, but the larger ones, I’m not sure. What is unfortunate, is all of the holes top and bottom, for the stock slider are directly above and below each other, so all of the added weakness from drilling is concentrated on that one vertical line.

I’ve also been looking at Webike for chain sliders, trying to find something that might work.

Interestingly, Takegawa has those large holes drilled in their swingarm for the Grom. I’m tempted to drill them as small as possible and force those rubber plugs in there.


In post #26, of this thread, noob claims to have installed the stock slider. I wonder how it is working out? I imagine it is just fine. I feel better seeing that Takegawa is doing it too. I doubt we are going to find a better solution than the stock slider.

I think I’m going to order a new Honda slider for the Kepspeed and see how well I can fit it. The slider that Kepspeed provides is not really of the quality I would prefer. I would have paid $20 extra for the swingarm, in a heartbeat, if they would have used a better chain slider.
