I know this topic probably has been gone over a million times but....
I have a 2001 ls650 bobber and I need to know is what shocks I can replace the stock shocks with. I'm a big guy probably to big for such a small bike but it's such a fun bike to ride. I would like something heavy duty and fairly stiff. the streets here are really bumpy and I bottom out a lot. any idea's please let me know.

And you can also use the search function to find the 20 other times shocks have been discussed.

It appears that the 4218 shocks are 13".  That is a bit tall for the bike unless you are doing a Cafe' Racer.  One other thing to pay attention to is the standard or Heavy Duty spring rating.  The Heavy Duty might be a bit stiff for the Savage....when you read the Progressive webpage they state the Heavy Duty springs are for Double Up riding, and probably they are talking about double up riding on 600+ pound bikes.

When you are buying used shocks you need to find out the shock length and the spring rate.....not everyone lists that.

The stock shocks are 10.5".  Something 11" to 12" is best for the stock cruiser look.  Taller than 12" and the back fender is way up in the air.

you can down load the catalog from progressive.

I'm 240 and the 412-1005? standard sportster shock are ok for me solo at the max setting, maybe a shade soft.  At least they are for the super x I do in the morning (I134w to I5n)
