Putting 12 inch shocks on a RK Classic and lowering the front forks 1 inch, lowers the whole Bike.

Figure out your own situation and run them yourself. There is a great deal of information and R&T calculators out there. Do a google search for rake and trail calculator.

And there you have it. Thanks QTR.

That is correct, the question was if only 1 is lowered (originally front).

TRAIL: The distance defined by the vertical line from axle to ground and the intersection of centerline of the steering neck and ground.
Is this how I read the trail measurements?
based on the diagram on the web, the trail has no effect when lowering just the front end?

The bikes rear end measurements are not even included on the Trails calculation. So why it is a must to lower bikes rear end when lowering front end? I dont need to do I? And bike is safe riding it that way.
By the way Thank you for this website.

That is correct, you shouldn't see any noticeable increase or decrease in handling with such small changes.

Not a problem, lots of useful web info out there

Yup, standard CYA legal statement. You can always verify, or use a different one.

Speaking of CYA. Don't take my word for it, verify the numbers for your individual situation. Viewer discretion is advised,

A little measuring with a tape measure and some quick math, you'll have the exact answer. As mentioned above, it's much ado about nothing.

I lowered my 2011 flhrc's front end 1.5" and it handled WAY better. much more responsive and controllable. No trail issues at high speed or fast acceleration.
