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.....

thanks....

I have the solid one and it has been bullet proof.

the hollow ones were an early design and will crack.

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.

Also the early ones for the pivot bolt bearings doesn't have a steel sleeve tout side the bearing for better support.

And the latest design swingarm does not have the "hole/opening" were the pivot bearings are pressed into, for better support.

i had the hollow for 2 years i rided in mx, desert and sand, a lot of mess and the swingarm is good as when i bought the quad no cracks on it
