I was reading the HD spec site today. I have seen the term

lean angle before, but I never really thought about it.

Is this the angle where the foot pegs will scrap the ground?

Is this the angle where the bike becomes unstable?

I am posting this here as I feel the shovel forum has the

people with the most knowledge about motorcycles.

 

Your close brother!

As in my 83 FXRT, probably one of the highest clearance bikes Harley made (for police service) It really doesn't come into play unless the angle of the bike needed to make the turn based on speed reaches too low (hightest lean angle) Not necessarly when the pegs scrape, because the pegs will fold up, it's where the base of the pegs will scrape. If you do add ons the angle will change unless they fold like the ones in factory specs.

I made use of it, as I raced Waterman Canyon out of San Bernadino up into Big Bear and Lake Arrowhead frequently. I folded the pegs up before I started and pulled my legs up on my bags, made use of the anti-dive a lot... lol. Also made a good chunk of change beating the rice rockets up and down the canyon. Could have been better but thing is, some of the turds didn't pay, and ran out on me as I sat on the finish line.

 

Lean angle is how far you can lean the bike over before something hits the ground. It may be foot pegs on some or pipes.
