Here's my problem; I set up for a curve, and as I begin to lean into it and start to accelerate thru and/or out of it, I am greeted with an ever-so-slight "dip" in the suspension. It's nothing so dramatic that would indicate a "sky-ground" experience, but, it is disconcerting. It only happens once, then it is gone and it doesn't happen every time.

I think I know what it is, but, I want to hear some input as it is my first Triumph and has been trouble free.

I ride a'00Sprint ST with 24K miles

Hey Yux,

I'm thinking that perhaps yer' kinda a big dude, eh???

The reason I suggest this is.....I'll bet you have'nt bothered to set up your sag heights (front and rear) and adjust the rear shock rebound setting.The original settings are set up for Liliputians I think and us bigger guys have got to make compensations. That's why the suspension is made to be adjustable.

I've an '01' Sprinter and a few weeks after geting it, I noticed the same kind of squat and wiggle in the rear. In the last 6 months or so, it seems every bike magazine and newpaper has had tech articles on how to set up the suspension. So, with that info in hand, I went about trying it out for myself.

Currently I've got one full turn on the front preload, and 13 or 14 clicks on the rear proload and the shock rebound is set with the slot aligned/pointed approximately at eleven and five o'clock, towards the firm side. I'm 6'4", 210 lbs.

Something I recently stumbled across is not only an article about this, but suggested settings for a number of popular bikes. Ironically, both our illustrious moderator and I are both running just about the same settings which are 2-3 clicks firmer than what Sport Bike suggested and a wee bit higher on the rear rebound settings.

Go to http://www.sportrider.com and click on the tech link. It'll take you to the suspension info. As mentrioned I've found their reccomendations just a bit soft, but since Don and I are now mature gentlemen, we're probably just a bit more husky than the young bucks riding/writing for Sport Rider.

Are'nt we Don?? It's all that manly demeanor we're forced to carry!!

And of course the possibility exists that at 24K miles, your rear shock could be on the fritz???? Adjust the spring to full soft and try adjusting the rebound from full soft to full firm and bouncing the rear end. If the shock has given up the ghost, you can tell by pushing down firmly on the rear end and if it does the ol' heebie-jeebies like a car with a dead shock (contiued bouncing effect rather than attenuating in one cycle) then the shock it DOA. If so, start saving yer' pennies for a good upgrade. You'll be glad you did.

Hope this helps???

So. Calif.

Dan'l is right on about checking your sag and all settings.
It is very well documented in several sources including RaceTech's site. IMPORTANT!!! On the rear preload DO NOT confuse CLICKS with turns. That adjustment is made through the 1/2 hole through the frame on the left side. Mine from the factory was set at 12 turns which was 24 clicks. Screw it down to bottom and then back out about 9 CLICKS and try that and go from there. I'm 5ft. 12 inchs and about 190.

Yes, It's fine to be a mature rider. When I ride up and take off the lid the gals think it the dogs bollacks :razz: "I think that means Okay in England. " Anyhow that's what a former girlfriend from there told me?

My rear suspension setup is fine it does not wallow in the turns, problem that I think he is having is that if you are on the brakes then transition from off the brakes to neutral throttle at the begginning of the turn the bike comes of the front suspension and upsets the whole bike. I feel the problem stems from no rebound dampining, if you are too late in getting off the brakes(if the bike isn't totally upright) you will be on your butt.

I have my preload on the front set higher than stock so I probably get more of the rebound effect than with stock, but with the stock it was too mushy and the front end would wallow in the turns.

My suggestion would be to find some heavier oil, and possibly go with some progressive springs. I'm now researching the progressives and will be going heavier on the fork oil here soon.

Good luck to you.

Hey guys, thanks a million for the input. The tip on the Sport Rider website is worth its weight in gold. I think my wrenches and knuckles will be getting a workout this week-end.

The last tip, from msparks, I don't think was appropriate in rectifying my situation. I didn't mean to imply that I was experiencing a wobble...more or less a sudden "drop"
in the ass end of the bike. It couldn't have been brake induced as I don't use the brakes.

Thanks again, I really appreciate you guys.
