Hacksaw or Angle Grinder
Flap Disc or File
Welder (Tig preferably)
Robem Engineering Subframe
Start by understanding this is a non-reversable modification. Not following these directions could result in permanent damage to your motorcycle or person.
Next strip down the bike and getting clear access to the factory non-removable subframe.
Measure from the start of the upper tube of the subframe that connects to the hoop of the main chassis. The upper tubes will be cut approximately 175mm. It is better to cut long and step towards your final dimension with a flap disc or file.
The lower portion is cut approximately flush with the tabs as shown.
The remove the original subframe by cutting squarely to the tubes.
You can see I leave approximately 5mm excess to both marks and reach my final fitment with a flap disc.
With the subframe bolted to the frame inserts check the fitment as you go. The subframe will be able to insert into the frame assembled when you're getting close to the final dimension.
The Tank, Tank Cover, and the Tail Section should be installed to help with alignment prior to tacking lower frame inserts in place.
Tack lower frame inserts in 3-4 places per insert to secure prior to welding.
REMOVE FUEL TANK PRIOR to tacking upper tubes. It makes the process much easier and safer.
Skip weld to avoid putting too much heat into one location until welded completely around the frame inserts. Repeat for each insert.
Stand back and admire your completed project and question why that lower tube for the rear sets at an angle bothers you so much.
