21" wheels on road king ??
First the 21 front = smoother feel at most speeds, a little tipsy at parking lot speeds, and a bit loose at 80mph plus.
Next front lowered 1"=Much more planted feel at all speeds. More feel for the road, and better tracking in the corners than stock.
Then the 18 rear w/ 150 tire and 1/2 inch shorter shocks.= the most planted my bike has ever felt, and what a difference in the long fast sweepers!!! wow! I for one love the way it now handles. and I do ride it, shall we say "Spirited".
*******, I lowered the front of my 06 SG 1 inch with progressive, and left the rear susp. stock with the 18 rear. The main way for me to describe the handling difference was this. I hadn't rode my bike after all the mods before saturday. I had asked Primo "what do I look for in the bagger brace issues. " I didnt know, I thought my bike handled just fine with the stock wheels and tires. Primo gave me this desription. "Well Chris for me it was a feeling like the back wheel wanted to keep tracking out on high speed curves.
It felt like the rear wheel was not following the same line as the front. Also when going over bumps it seemed the rear wanted to slide out a little.
Once I had the true-track installed my ride immediately felt tighter and the back no longer feels like it is straying.
Others make similar devices but True-Track invented the concept. I've always felt it important to reward the inventor of a product even if it costs slightly more that to reward another company for simply ripping off an idea.
It was probably the single best improvement and purchase I've made for this bike and believe me I've made a ton of changes.
Feel free to ask any other questions. I'd be happy to share what I know.
Ride safe,
Primo"
Now I know what he was describing to me, I rode it about a 100 miles saturday and if I didn't realize the bagger brace symptoms before I do now. I do plan to lower the rear an inch after all but I am in no hurry.
hope this helps.

I can't tell any huge difference in the way the bike handles with the bigger wheel on the front. Of course I changed bars and added an Arnott air ride to it at the same time so who knows what changed what on it. I ride pretty aggressive on curvy roads. Well as aggressive as you can get on a 800LB recliner any way.
