I have an intruder 1500 which was triked around 5 years ago with a reliant robin rear end. Although this steering wobble has always been there and being new to trike riding I thought that this was normal. I feel that this problem is now getting worse. Does anyone out there know how to solve this problem.:gah:
extreme steering wobble at low speeds

Hi Gazza, and welcome! I could be way off here (someone will let you know if I'm wrong), but the way I understand it a stabilizer will ease that front end wobble, and a rake kit will make the overall steering easier. Bazooka or one of our other members will undoubtedly know better than me! :yes:
I have the Suzuki C50 with a Lehman trike kit. The dealer told me that there would be a front end wobble at low speeds - this is common, apparently. The C90 isn't as bad because it has a stabilizer (again, according to my dealer), and they now make one for the C50 - maybe you could check with a dealer and see if one of those stabilizers will work on the Intruder. (Other than the fact that they're both Suzukis, I know nothing about the differences between the Intruder and Boulevard)
Good luck, ride safe, and have fun!! And again, welcome!!

Check your steering head bearings, they may be loose.

Welcome aboard, the steering head bearing need to be tighter then they would normally be after the bike is triked. See if you can tighten them down so that the steering will only swing about one pass if you have th bars all the way to one side and let go with the front off the ground.
The Intruder, and C90 are in all aspects the same except that the Intruder is carberated. The low speed shake is normal for them, but the tree stem nut needs to be a little tighter ( don't know just how much ), and you should have a steering dampener. If you don't that is more than likely where it is coming from. Also it will get worse if you haven't had a damper with tire ware.
Hi Gazza. With many short wheel base trike conversions, you will have a steering wobble at slow speed and deceration, especially if you remove one of your hands from the handle bar.. Tightening the bearings may help and a steering dampner will as well.. But if this wobble was there from day one, you may be in need of a raked front end (easy steer)... That will normally fix up any wobble straight away.. and make your trike a bit easier to ride and equally more fun with less rider fatigue on longer rides.. I've have a few dealings with the guys/girls at TRIKESHOP.CO.UK in the past.. maybe they can help you out! Good luck!
My '07 C90 came with a steering dampener and it still had the low speed wobble. Checked the front tire for cupping then tightened up the steering nut even more. The issue finally cleared up when I had Steerite rake the triple tree and I added 2-inch fork tube extensions. There is still some wobble occassionally, but it's reduced to barely noticable.

Good input, Yogisan, and I agreed wholeheartedly. Not to negate any advise here necessarily, but steering dampeners for these problems are at best a band-aid. Steering geometry changes significantly when a bike is triked. And having owned a C90 myself (two wheels), I am aware that they are sensitive in the steering department already (seems to me like too much weight on too soft front springs, but I never really delved into it much).
Make sure the stem nut (main nut on trees) is tightened a bit more than stock, check your tires (all three) to insure good tread, correct air pressures, and beyond that consider the 'raked tree' solution (although costly unless you are good with a wrench yourself).

+1 on all the above. I rode a trike for a couple of years and it handled like a dump-truck......UNTIL I raked it. Serious low-speed wobble and would wear you out (as well as scare you to death) in the curves. Raking mine improved curve-handling to the point that I can ride with any of my 2-wheeled buddies and I now have power steering. I have read something somewhere concerning the difficulty in finding a rake kit for some of the metric rides, but there are some companies out there that will take your stock trees and re-work them to add some rake. 3-4 degrees will make all the difference in the world.
I guess there are a number of possible causes of wobble. I just corrected a serious wobble that was in my gl1800 trike since I bought it last year. There was a tire sealer/balancer in the tires, called RideOn. I had the tires removed, cleaned out and reinstalled, then spin-balanced. Problem corrected 100%; hands-off, no wobble.
The main source of the wobble seems to have been the rear wheels. Maybe one of your tires is OOB?

Can any one explain "only swing about one pass" I can't figure out what Gorilla is telling us.
thanks
Lucky, I asked on this thread thinking that there might be more members (hope I'm not the only one) that also don't quite understand what Gorilla is talking about, also I'm not sure how to go about sending a PM to a member. Can some one fill me in please?
Thank you for your reply

Okay guys I will try and be a little more detailed. If you raise the front of your trike off the ground so that the handle bars can swing freely from side to side freely. You just want to clear the ground a little. You want to make sure that the handlebars will swing from side to side freely. You take the bars and pull them full left. You let go and the bars will swing to the right to the end and then reverse back and forth until they stop. A properly setup (tighten down steering nut) on a 2 wheel Harley Touring bike will swing approx. 2.5 times before stopping. (left to right is one swing, right to left second swing, back to about the center is the half swing) What you want on a Harley davidson touring trike is for the steering nut to be tight enough that you only get the one swing from left to right then it stops. I hope this helps.
I have GL1500 trike and I had the same problem at low speeds. I upgraded my springs from stock to progressives and reduced the wobble to almost nothing (no wobble going straight).
I had an 03 Intruder and after talking with other owners this seems to be an issue over time with the front end. Like wing owners they eventually would switch over to an All Balls style bearing or a Timken bearing in the neck to tighten up the front end. The wobble will only get worse over time. You can tighten it up and it will work for a while ,but then it will slowly come back. The best thing you can do is replace the bearings with a better sturdier bearing.
Does anyone know what a solid rake angle should be on the front forks?My two wheeler is 32-35 degrees out, same as the head tube angle.So my guess would be 35-40+ degrees out.I really don't like raked bikes or trikes,but I wanna be sure I eliminate any head shake/wobble because my GF will be riding the trike with our son on back.
just to be sure of the concept here ..... for a trike when the front is "raked" we are not talking about the frame but rather the trees...
have found about six degrees in the trees works for me depending on what bike....... with six i have very easy steering...and i dont use a damper
all a matter of preference... some say i am nuts going so much.... but i have over 42k on my vmax since the conversion and over 30 on the harley
never had and issue
do wish i went more than six on the harley though
