so i jut realized that there is a swing arm that has a cut out / hollow in the center? can someone explain; is there any weight savings there or less durable? i have what i though everyone else has which is the solid one.....
The earlier ones with the open center may be just a little lighter but not too much. They would work best for drag racing or maybe some light duty trail riding. Both of my quads originally had the open swingarm but I changed out mine to solid ones for mx use.
Also on a side note. There can be another difference between swingarms. Most of the earlier ones have a 10mm shock bolt hole and some of the later ones have a 12mm.
