Monotube questions

I've read numerous posts re: mono tubes and I'm not questioning the improved performance received from their installation. My question(s) concern lowering. My ride is a 2012 RG custom I do not want to lose clearance when cornering. I am running stock rims and tires (size wise) and do not plan to change. Everything I've read says that even the stock height monotube drops it an inch or am I misunderstanding the use of the term lowering.
I'm 5' 10" 200 30" inseam so I can flat foot no problem, 2 up wt runs apps 350.
Aggressive cornering so even 1 up floorboards touch down.
Given all this am I making a mistake getting monotubes and if not are the 31-2500 the ones I need.
Thanks

From what I am hearing off this forum. That part # is the kit that keeps your bike at stock height. The other kit is the 31-2501 which lowers the bike 1 to 2 inches.

I dont feel it lowered mine at all. I only used one spacer per side too. The kit comes with two spacers per side. Using only one per side lowered it 1/4 inch from full stock height.

If I have to explain ,you wouldn't under stand anyway.

I have the stock height kit installed with no c clips. This lowered the bike 1.5 inches.

The FLTRX is an inch lower than the FLTRU anyway, yes? Perhaps progressive is going by the height of the ultra?

Actually the front forks are identical on both models, the 1" difference is only in the rear due to shorter shocks. To the OP, with the standard monotubes and both clips installed there will be very little or no change in height when sitting static. The big difference is when you push it into that turn the front suspension doesn't compress as much as the soft stock springs so your ground clearance remains the same or better.

Varied opinions on this topic... this is one of the most accurate responses. Like someone posted above, I also talked with progressive directly. To add to this... the stock height kit can be used without the c-clips and lowers the bike aproximately .5" - 1" depending on the kit. The lowering kit gives you the option of lowering, in their words "1 or 2 inches", however, the taller option lowers the bike about 1.5" from stock height. You can add a 4th c-clip (1 more than instructed but included in the kit) to raise up an extra 1/4". Or the kit can be ran at its lowest setting for a pretty accurate -2" height.

Just throwing in my 0.02$ because I installed the lowering kit for -1 and it lowered mine more than I wanted with stock wheels and tires.
