What you need to measure to see if it is actually a 2007 swingarm is the length from pivot point to axle point. The 2007 onwards swingarm is about 15mm longer and if you wish to use the later swingarm you will need to get the appropriate longer belt also. It is not necessary to change the swingarm to do the 240 conversion, there are many threads on here with good info and this picture pretty much tells all.This sounds like the place for an answer to my question , I have 2003vrsca , bought a swingarm locally second hand - supposedly from a 2007 vrod , the swing arm is the same width - arm to arm internally as the original , so could you tell me the width internally I should be looking for ?
width of second hand one u bought is 293mm or 11.5354 inches for those of you in the states
(That’s between the axle points )
To answer your question about the width I just looked at mine(difficult to measure as it is on the bike) and I would say it is about 300mm. I would say the arm you have is probably not an 07 on arm, but check the length.
