so what year/model was the roller?

To do it right you need a mix of parts

All the main parts swap between KTM models in the same generation.

07/08+ 2t rads
07/08+ 2t carb boot
07+ 450/505 sxf/xcf frame
07/08+ swingarm (all but the XC4)
07/08+ shock
04?+ 2t coil (or any 04+ coil with a 2t cap)

The easiest way to do it is go get a 08+ 2t roller and add the 4t frame.

What specifically did i use? honestly I'd have to look at the parts to see what years I grabbed of the shelf. I have a large pile of KTM parts and just picked through the pile to find what i wanted.

The 550 into a 07+ ktm is being done currently. It is not even close to easy swap. The swing arm, frame and intake need considerable fabrication since everything is on the wrong side.

The Honda into a KTM is easy... Easier than the honda into a honda AF swap

Wicked build, it makes so much sense to use a KTM roller don't know why you don't see it more often.

It fits with so few mods It's almost like the chassis was made for the motor.

I built this over the span of a few months, but if you started with a running engine and had all the parts, you could knock it out in a day or two at the most.

The only custom parts are the frame mounts, head stay and the exhaust and even that isn't much work.
