Default 18 or 21??? Riding two up

Hey guys looking for a little input here. I have a 2012 Street Glide. I ride two up 95% of the time. I changed out the rear shocks out and went with Progressive 940s. Only reason I did that is my wife has lower a back problem. I going to put monotubes up front. Now my question is with all that said am I going to loose my ride confront if I put a 21 up front? I'm more worried about her loosing the comfort. Or should I just stay with a 18. Thanks in advance

On paper the 18 looks more comfortable due to tire volume, but in the real world the difference is negligible.

No noticeable difference, go with the 21 and you will not regret it

I installed the 21" first then installed the front progressive lowering monotubes. I ride 2 up 90% of the time and the bike handles better at low speeds after lowering the front 1". If you don't lower the front the bike will leans quite a bit on the jiffy stand. In my opinion lowering the front is not required but I prefer it.

I'm not sure, it's going to depend on your wife. Back injuries are like women, they may have similar characteristics but no two are the same. Seat angle, rigidity, vibration...etc, are all bound to play a role, you'll just have to be willing to make changes till you make her happy. You're just as likely to make her less comfortable as you are more comfortable with each change. Some of the changes we made worked wonders for me but reduced my wife's comfort. Keep working till you both get there.

Good luck.

The 21" crosses expansion assemblies in the road with less feedback to the bike vs an 18" but for her sake, a king tour pack that supports her under the arms and a better seat really make the difference.

I d suggest getting a different rear shock sas the Progressive 940's are known to be very firm. This is all about suspension. Just as stated above a bad back has many characteristics.

The 21" wheel didn't cause any ride issues for me. You will lose a bit of suspension when you lower the front 1". I noticed that more than the wheel. I doesn't bother her at all. Changing the rear shocks to ohlins was the biggest difference for my wife. She tells me how brilliant I was for doing that everytime we ride. Now if I could just get her to do that off the bike.

I have did the king tour pack and hammock seat. All of that help a lot but the stock shocks never hold air check all the lines for leaks and no leaks. Talked to my dealer and they just giving me the run around. So that's why I'm doing Progressives. I was told they'd be like the ultras or not?

Did you try clipping the very ends of the pneumatic lines then reinserting them? I always change out the fluid in my rear shocks to 10 weight especially on the 12" street glide shocks.
