sorry I didn't understand. Are these 10" bars and they don't bolt on without modifying something? They look bigger tthan 10".
I checked again and this is a Paul Yaffee OEM Monkey Bar from
http://www.custom-chrome-europe.com/cce_about.html?&L=1 and they sell a 9" version with 32" wide , the owner of the orange SERG from the pic told me that he had to modify something with a dremel because the hand-control-units are too tall ( the reason seems to be the hydraulic clutch - i guess that this problem will only appear with this 9" 32" wide bar , because the Paul Yaffee site shows a 33" wide at the 10" , maybe the horizontal part of the bar where the handcontrols will be mounted is a little bit longer at the higher Monkeys )
The pic below from the Paul Yaffee site should be the 10"
When you check the details of the two pics then you will see that the Paul Yaffee site pic shows a bike without hydraulic clutch .
If you look at the SERG pic then you will see that the " hydraulic clutch tank "at the left side is very near at the point of the bar where it runs a little bit up , before the bar goes straight down .
Maybe he had to dremel-away a little bit material of the bar to be able to move the handcontrol-unit inside or onto the bar .
