I did not touch the TP motor weight other than to port, polish, add to cam cavity clearance, but added weight using a Bandit clutch and 6 speed. Another gullible person here. If one wished to own a aluminum swing arm before they die, so be it. Better than spending it on Michal Jackson's little boy hush fund! If one wishes to thrill with their HD, go for it.

Making a swing arm is not that easy, talking about it is, however. I found that not that many HD riders care too much about weight, performance, or for that matter, how their bike rides down the road. The real deal is if you made a rear fork and tried to live off of your earnings from performance oriented Harley Davidson owners. The folks making big shinny wheels, chrome gremlin bells, and assless chaps do quite well. Many on this forum do not know how to read a metric rule nor have a clue why great brakes are a good thing.
