Well, we'll see how this swingarm does. I hope to have it installed in the next few weeks.

I've seen a lot of these where the bearings failed. I'm curious to know if MNNTHBX bushings would fit as a replacement.

Mine is installed and I love it. :)

I live in the middle of a canyon so I'm going around curves more than I'm going in a straight line, and handling is more precise and predictable with the Kepspeed. :)

I haven't. Could you provide any references to that? I'd be interested to see them.
I've seen people having problems with the bearings being shot on the french interwebs, no pics I can remember of, just people asking where and how to change the bearings, sounded like those were hard to find.

Time will tell, I guess. For the price, it's worth a shot. Looks better than the stock swingarm, that is for sure. ;)

I'm willing to assume the minimal risk of unfounded rumors. ;)

The swingarm is part of my weight reduction mods, and it dropped a hefty 4 pounds. My bike weighs 208 pounds, down from 229. On a little tiny bike with a little tiny engine, believe me this DOES make a difference.

I would think needle bearings would live a long life in this application. That being said the potential to ruin them on a careless install is also greatly increased over the oem setup.

Installation basically consists of holding the swingarm in position while sliding in the long pivot bolt, so it's pretty hard to screw up. There was room in the frame, so I installed thin washers on the outside of each side of the swing arm to act as grease seals for the needle bearings.The range of motion of the bearings is similar to the needle bearings in driveshaft universal joints.

Oh, I didn't mean they would be hard to install. I was just imagining someone driving in the pivot bolt blindly with a hammer. That might not end well. I am keeping an eye on these for a future upgrade. Thanks for all your feedback!

It sure is appealing for the price! My comment is just a friendly heads up to check the bearings once in a while.

Why would you say it's ''unfounded''? Is it because I don't have first hand experience with those?

Thanks for the heads up. I'll give them a look from time to time. Hopefully, the welds hold up too. :)

Welds would be my biggest concern and are the reason why I didn't buy a cheap (or inexpensive...) swingarm in the first place. :)
