The Street Glide wheel was a used one off of a 2013 Street Glide with about 5000 miles on it.  It was loaned by a friend who switched to a set of 18" and 19" Agitator wheels.  I only changed out the front wheel which immediately eliminated the twitchy feeling.  As before, I had done everything to eliminate the issue before I tried changing the wheel out.  I am anxious to try out the new Street Glide to see if the new wheels which have a very similar design to the "Chisel" wheels produce the same twitchy handling.

I have finally installed the new wheels and tires which has corrected all the twitchy handling.  The bike now rides and handles as it should have from the factory.  The Motor Company has NOT accept any responsibility for the ill handling of the bike.  All conversations with them has been that it is within specs.  Even though changing the wheels was done on my dime, I am happy to now have the bike I thought I bought in the first place.  I went with a 17x6 with a 200/55 in the back and a 18x3.5 with a 130/70 in th front.  The wheels and front rotors are from Performance Machine and the tire are Metzler 880's.  I will post several pictures of the finished product.

Looks great!  Glad that you, like me, have a bike that is worth riding now, even if we had to pay for it ourselves.

Glad this worked for you. Interesting that you went up one size on each tire. Did you also make any mods to the suspensions? And on the Metzeler tires did you go with the new 888's or the 880's?

The changes to the suspension include JRI rear shocks from Howard at Motorcyclemetal which are wonderful and Racetech with gold valves in the front.  I used the Metzler 880's since I have always had good luck with them.  Here is a picture of the rear shocks on the bike beore I changed the wheels.  Thanks again to Ernie  :orange: or I would still have a bike which was un-rideable.  I would never have thought the design of the wheel could have caused that much instability.

Yeah I loved the 880's on my last Ultra. I just put on the new 888's on my 13 and love them as well. Much better than the Duncraps that come stock

I agree, I will not run the Dunlops D407 and D408 on any of my bikes.  I talked to the Dunlop rep at the 110th in Milwaukee and he said the tread pattern is a Harley design not theirs.  That is why they are selling the 2nd Generation American Elite through non HD dealers.  I haven't ever had a rear tire cup until I ran a D407.

Just to add my tuppence worth.... I have always thought that 2012 ultra was a bit nervous in windy conditions and a bit of a handful when coming up behind large vehicles; especially just before you would pull out to pass if it is a windy day. I had just assumed the fairing was to blame but how wrong I was. Last weekend I met up with an old mate Steve on his standard 2011 ultra and my normal riding buddy Grant, who was on his fat boy low. It was a perfect riding day with just a slight breeze and after about 40 miles we pulled over to swap bikes around. I was surprised when riding behind Steve, (who was on my CVO ultra), that I could see the effect the draught from the bus in front was having on the CVO. As I then came up behind it to pass, the standard ultra was not affected in any way by the turbulence from the bus and at no time did I experience any issue with the handling on his bike. When we stopped for food and a chance to compare notes we all came to the same conclusion that the CVO ultra was badly affected by wind/ turbulence compared to the standard ultra. N.B. My CVO ultra has 1500 miles on it, Steve's ultra has just over 8000 miles on it and is still on it's original tyres.

I am so glad you got a chance to ride another bike to see just how much a problem the Chisel wheels cause with the handling  My wife and I just traveled on a extremely windy road in Nevada (the highway had high wind warnings posted during our ride).  This road is also grooved for rain and snow.  Our bike with the new wheels was rock solid, without a hint of twitch or instability, at speeds up to 85 MPH.  We would never have been able to do that before getting rid of the Chisel wheels.  I recommend you change out your wheels with anything else and your problems will be solved.  Good luck.

My 13 CUSE 8 is at the dealer now for this very same problem. I have always felt that this bike did not handle nor ride very well. It is the first Harley I have ridden that I cannot take my hands of the handle bar for even 1 second without the bike diving right or left.

Hard to explain the problem but it just doesn't "feel" right and the turbulence when within 300 yards of a truck is very noticeable.

Let's hope they find a problem and that I do not receive the standard answer of "they all do that" or cannot duplicate.

Just another of MOCO's non support making the customer pay once again. Glad you got it sorted out though. This is really a safety issue, thanks again for nothing MOCO.
