4 of 5 Well made but not a completely true reproduction January 20, 2021
taco eater : Ian Templeton from Seattle, WA United States  
I have owned two of the Malossi square swing arms over the years, so I was really excited to see MLM is reproducing them.

Some of the dimensions seem a bit off. definitely won't work with stock mag and brake plate without brake plate modification. Does work OK with the Bernardi 5-star and 2.5" tire [I used a 200mm axel with a 26mm and 13mm spacer].  

Main issue is that the peg mount is located pretty much exactly where the exhaust should mount up. Another issue is that due to brake plate and brake plate stop dimensions, the wheel sits pretty far to the drivetrain side, resulting in not much clearance on the drive train side and a lot of unused space on the other side.

Also, the angle on the side stand mount is probably too steep.

Basically, much more sturdy swing arm, but expect to do some fabrication to get the most out of it.

5 of 5 Good for at least 1000 miles March 12, 2018
taco eater : Maitland Kelly from san francisco, CA United States  
I ran one of these on a motobecane frame with a minarelli engine welded into it.

Not only does it stabilize the frame by kicking the rear wheel back an inch or two, but its super beefy for a big boy like me.

Gonna put another couple thousand miles on it this year hopefully.

Also the fully captured wheel adjusters are a huge improvement. Big improvement all around
