Title: Heavy Steering!
Post by: ssduc750 on September 30, 2006, 07:20:10 PM
I lowered the rear of my bike due to short legitis. Noticed at the last race that the steering was very heavy. Bike didn't want to turn at all. Should I now raise the forks in the triples a mm or 2? 

Thanks :banghead:

Is there a general starting point? Say, 2mm's and go from there? Or does it depend on how much I lowered the rear of the bike.

I am sure that there is a formula but you said you lowered it becasue of your height challnging heighth. You Jason Disalvo is real real short and he doesn't lower his...unless this is for a street bike. I would lower 2 mm then go out for a session. If it is unrideable then lower them some more. Repeat until you find that you are 1. Losing the front end. 2. It turns on rails. Thats the way most people do it. OR you can call a suspension expert.

Think I'll go with the last suggestion.

Rocco,

+1 on suspension expert. Bring your bike to Ed Kwaterski.

ROcco, I was very tippy toed on my F2. Once moving its height wasnt an issue.

If it's a street bike, it's not a race bike.

If it's a race or track day only bike, then there is the great probablility that it is going to be pretty tall to allow the combined center of gravity to transfer weight better to the front and back.

Man, I don't know if I want to take advise from a male stipper!! 
All kidding aside, I plan I putting on new forks over the winter and the first day at the track the bikes going to
http://tracksideengineering.com/ to be set up correctly.I appreicate all the advise from people much more informed than me. I have neither the time nor the experience to screw around with something that important.

Egads!  Lowering the rear of Duc?   Racing a Duc w/stock geometry is like Sumo wrestling already, lots of body english, grunting, groaning to move a huge object a few feet  ::)   Man, if you're not smaller than Dani Pedrosa, I'd get that rear as high as possible. 

Ditto on the advice for trackside set-up help...a few bucks can move the bike closer to the bulls-eye instantly. 

For more than a few bucks I had Kent Soignier at GMD Atlanta optimize my Duc 750SS, which transformed the bike:
