Its my understanding that radial tires are for the 1800 only. Michlien Radials were put on my 1500 by a dealer,. I hadn't really paid attention until I had them replaced with less than 9000 miles. The Bridgestone bias thery were replaced with don't hamdle nearly as well. At a high speed of 75mph or more on a interstate curve it wants to develop a wobbly sensation much like front end slow speed wobble. This isn't fun around 70 or 80 mph. The radials handled much better, but the wear was horrfic. Have any of you folks ran radials on your 1500?

1. Slow down.

2. Check steering head torque.

3. Check front and rear suspension.

4. Install fork brace.

Many have had them in the past and loved them but Michelin saw fit to remove them from the U.S. market

The only radials recently available for the 1500 were Shinko's and they were junk and no longer available. A friend of mine had them on his bike for a while and thought his frame had cracked it wobbled so badly. Changed tires and everything is fine. I had great luck with Michilin Pilot GT's and dynabeads, around 14000 miles.

Hi Bob, have progressive shocks and fork brace. I'll check steering head torque. If alls checks ok....... well I guess I could slow a little.

James, be sure your rear shocks are work as they should. Weak rear shocks can and will affect the front.

Bob is right... worn rear shocks will create that Front end wobble you have.

I put Progressives on front and rear, and it made an A-M-A-Z-I-N-G difference in those high speed corners. (In combination with Elite3 bias tires).

WHY ARE THERE SOME PEOPLE THAT JUST CAN`T ANSWER A QUESTION WITHOUT GIVING THEIR TWO CENT`S WORTH ? Yes james radials do handle much better [ my experience ] but the trade off , especially with motorcycle tyres is the wear factor . Whilst Michelin did for some time make a radial for the GL1500 called 79X , they no longer make or sell these tyres , there are some other radials that will fit the GL1500 but none as good.[my experience]So we are left with a lesser handling tyre than we had but there is no other option and I am now running Michelin Pilot GT`S bias ply`s on my GL1500 and while getting bigger mileage the bike is not handling nearly as good [my experience ]Now if you did not have a wobble and only had new tyres fitted would it not make sense to some that it just may be the tyres ?...ps I am a mechanic ...Noel

Hissey fits????
Absolutely- It very well COULD be the tyres- but- (in my experience) it probably isn't. AND (in the experience of the others - at least three of which ARE mechanics) they have proposed possible fixes that (in their experience) has solved this problem before. I, for one, appreciate their input which adds up to decades of solving these type of problems. A litle levity here and there makes life interesting. Ed

James, just to correct a point, Michelin does still make and sell the radial (Gold Standard 79X) for the 1500. They are just not available in the North American market. The Shinkos are a good handling tire, but they will not stand the stress of a 1500. The bias Bridgestones are junk for an aggressive 1500 rider, but are great for the Sunday ice cream riders who want mileage over handling.

When you say "interstate curve" are you talking about "flyover" ramps or just normal curves? If they are "normal" curves, then your bike shouldn't even notice them, unless you like in the mountains and are running I-5, 26,40,77,81,84 and such. You haven't filled in your profile, so I can't tell. Every bias tire I have ran had a bit of a wobble on the high speed flyovers, but that is a geometric force issue and not the tires.

Just my .04¢.

Didn't say but progressive on rear as well. Jerry, you must be familar with I-40 where you head up the mountain west of Old Fort. That was scary 60-65mph with bias. With the radials, no problem with radials. Worst wobble going on overpasses with curve.

You must be talking about the bridge over Hwy 70 and the RR tracks at Old Fort unless you were in the gorge.

I can't speak from experience with the peE-3 Dunflops, but I know when I went way backwards from the Michelins to the peE-II, it took me less than 3 miles to need to stop and clean out my shorts from scaring the poop outta myself with them. The bridge I'm talking about has grooves in it, and it's possible you were catching them, and getting used to running crap tires at the same time. Do you have the problem anywhere else?

The overpass you are talking about is in Black Mountain, NC and is known around here as the Richard Petty Bridge.
