Compared to a few other wheels I've seen pictures of I have quite a bit of material left. Compared to modern wheels these things are pretty overbuilt.
I didn't weigh anything before I started, so no clue on how much weight was removed. I did it more for cosmetics.
Simple?
What is the reason for lengthening the swingarm?
More weight on the front wheel, possibly longer suspension stroke at the rear wheel (depending on shock specs as well)Less tendency to wheelie and perhaps steadier handling at high speeds?
