Unhappy Now Mine Is Shaking/Front End Shimmy

Fellow Riders, I have a 05 K1200LT which I just took in for new tires my old ME880'S took me 16.000 miles and could have went another 1.500 or so. But I decided to get new shoes before the dealer gets over loaded with work and would not be able to install new tires for weeks on my bike. Or I lost it in heavy rain in a corner or the dreaded flat. The bike rode well on the worn tires the weekend before over 450 miles my first long ride this spring. After getting new tires I was downshifting from 5th to 4th and the thing shook me good at 45 or so,pulled over and scratched my head wondering if I hit something or if the pavement was rough this was not the case. I got back on her got up to speed down shifted again from 5th to 4th it did It again. Back to the shop I went and left the bike with them ,they called me back to tell me my rims were out of true. I could not accept that as the problem even if it was so for it rode fine for over 450 miles on worn tires and new ones made it worse? Well I'm a poor working stiff like most of you and buying new rims at 1.300 is not a reasonable option to me. They rebalanced the tires and it helped a little and sort of checked the steering stabilizer but the verdict is still out on the problem. Words of wisdom would be appreciated about what to do because I don't believe I need new rims the slight truing problem was there before and was not bad enough to cause a shimmy before, Is this a reasonable conclusion?Thanks

First Off please fill in your profile as it helps to know who we are helping. Second, you can block up the front wheel and spin it your self and place an object close to the tire to check for out of round. Then hold something close to the edge of the rim and check it as well. I think you will find the TIRE is out of round. I had one I installed myself and it gave the same shake on decceleration through 45. The new tire was out of round slightly (maybe a 1/16 of an inch). I went a head and wore it out and the next ME880 I put on was true and the shake is now gone.

So get a second opinion, another bike shop or dealer or have this one show you that the tire is true and your rim is out of round (very unlikely).

Good Luck

What tire did they mount? Some times the tire is just flat not balanceable.

i could be wrong, but it may also be a broken belt in the tire, i would ask to see if you can get another tire. that is unacceptable

Old tires no shake, new tires shake. Bad tire or they bent the rim mounting the tire.

I agree bad tire or bad mounting job.
I only got the shake at 40-45 mph when I had worn tires.

Just Go

Had two LTs in the past.

Both did the same thing, but always with different tires. Which tires you ask?? Have no I idea. With fresh tires the wobble did not happen so I can only guess that it is a tire problem. I am about to put new rubber on the LT and can tell you now that I have Bridgestone, "wobble" at low speed and putting on Mets, that I had before no "wobble". I would say this normal with the LT and it gets better with age.

This is probably way out in left field, but I had a problem with very low speed front end wobble. Lots of diagnosis, but the bottom line was, LOW BACK TIRE PRESSURE. Can't believe it was that simple, but it was down about 20 pounds. Raised the pressure to 48 and all problems went away. Not one tech caught the problem.

Front End Shimmy Advice

Thanks to all who responded to my situation. I have past the input on to my Dealership and they are considering every option suggested and are working with me on the issue. The owner said he does not think my rims are the problem but the new tires either the rear or the front the rear being his first choice.

My bike started out with Dunlop 020's......had the front end wobble.....changed to Metzler 880's......still had the wobble.......dealer changed out the lower steering yoke.......still wobbled....installed 205's......no more wobble.
Good Luck........

Just had 2 new tires mounted. drove 1/4 mile, and had a wicked wobble. I turned around, and returned to the dealership. Told them to replace and "really" balance the front tire this time.

I marked the mounted tire as bad, so I would ensure it was changed. new tire, and a good balance job, no problem.

hey Patterson

when you say 205's do you mean the Dunlop 205s?

This is the first I have read of anyone using 205's?

Thanks

Hi Glen..............Yep (had to go peek at them just now to make sure) they're Dunlop 205F (front....120/70 B17) and 205D (rear .....160/70 B17). They do sit noticeably taller than either of the 2 previous tires.....on the centerstand, I may have1/4 inch under the rear wheel.

Can you give us (tire watchers) more info on this tire? Cost?, and how do you like them? are they rated for the weight of the LT? how many miles you getting?
Thanks

OK i'm sure i'll make alot of enemies here but here goes, the lt is a piece of shit. I've been riding since i'm 11 and have had many bikes. (i'm 45) I bought my bike from what i believe is the best dealer in the us. (Hermy's) he tried everything to get no just one but two lt's to not wobble. (my friend bought one the same time i did) He tried everything. More then i want to type. Bottom line my friend filed for lemon law and won, Hermy gave me a great deal on a 06 gt and i love it, no problems. the bike has a problem with its design. They all shake some feel it some don't but it will not go away. Sorry for the bad news. I almost bought a gold wing but didn't, but i did get to test ride it. It would wobble but would stop immediately. My friend bought a rt, I have a gt and i'm happy. I love BMW's i've had a gt, rt,lt and now a gt. I love bmw's but this bike just isn't right.

Shimmy in Front

I have experienced the same on my 2005 LT. at 40 MPH if you let go of the handle bars for just a second, it would scare you. The dealer replaced the tire, rebalanced, and ultimately replaced the wheel. It helped but still had a shimmy although slight.

At 12,000 miles, I replaced both tires and the shimmy is completely gone. I think the LT must require exceptional tires and a near perfect balance. I would return it and seek rebalance to start with,
