...but the dangers of scraping hard parts is properly demonstrated.
Rider skill set aside (though we can see the riders upper body on the outside of the center of his bike.. ahem), the photo show clearly that his crash bars (oh the irony) touched down, levering his front wheel up enough to cause a loss of traction and a low side.
I had a friend low side on her lowered Sportster due to her touching down the big, way far out peg carrier on her bike. Can't comment on her body position at the time, as she was behind - but i know her speed was below 30, probably below 25. So, even at low speeds, touching hard parts can significantly compromise your traction.
What if you are 148 clothed and about 160 in full gear.
At that weight, you're fortunate. The stock springs will probably suit you just fine. But it would not be a bad idea to take it to a shop or other skilled individual to have the settings gone over. And don't mistake someone who can work on and engine for someone who can set suspension. I've got no problem pulling a part an engine - did my first 100% dis assembly and reassembly of an engine in 6th grade (and yes it worked after

) - But I deffer to others on suspension settings.
