Lowrider S vs Streetbob Rake Difference
The HD website says the Lowrider and Lowrider S rake is 30.5 degrees at the steering head. The site also says the Streetbob rake is 29 degrees at the steering head. Is this the only difference in overall rake or do the bikes have different triple trees?
I ask because I am considering putting Streetbob triple trees on my Lowrider S to decrease / improve trail. A forum member told be the forks were the same length for both model numbers. Can anyone confirm or deny?
Thanks in advance.

Sbob 0° Trees
LR 1.5° Trees
If you keep everything the same on your LR except for adding the 0° Sbob Trees (decreasing tree rake)...you will INCREASE your trail
Looks like the Tubes are same length (same # non cartridge side)

I am confused. Someone needs to break this down for me more I guess. My Lowrider S has the same size tires and same height rear shocks as a Streetbob. If I change the triple tree to a Streetbob triple tree (and you say the forks are the same) then my trail should be exactly the same as a Streetbob in my mind.
The HD site says the trail of a Streetbob is 4.7 and the trail of a Lowrider S is 5.1. How is your math calculating that adding Streetbob triple trees will increase my trail?
Anyone else care to chime in?

You need math to arrive at a value...You don't need math to know how changing the Rake affects Trail (increases or decreases).
After your statement..."I am considering putting Streetbob triple trees on my Lowrider S to decrease / improve trail"
You were basically saying "I'm considering putting triple trees with less rake to decrease trail"...I was just trying to get you back on track.
TREE RAKE
Take any given bike and ONLY add Trees with LESS Rake ...Trail INCREASES
Take any given bike and ONLY add Trees with MORE Rake ...Trail DECREASES
Btw, Neck Rake and Tree Rake affects Trail in opposite directions
NECK RAKE
Add LESS Rake to the Neck ...Trail DECREASES
Add MORE Rake to the Neck ...Trail INCREASES

Here's a calculator to prove the Theory to yourself...Values are for comparison
"ONLY add Trees with LESS Rake ...Trail INCREASES"
Hope it helps
