Front Shock Factory and Weight Variable Settings...??
Permalink  
 

Dear ladies and gentlemen of TTR addiction,

Sorry, No, I don't know the front fork settings but would love to know? I've checked my manual, nothing there. Checked a few blogs, including this one which gets close, but no one has nailed it yet ! So....

Does anyone know EXACTLY where/what the factory settings are? (My model 94 Open Enduro) ?

  AND...

Can anyone give well qualified/experienced advice on settings (+/-) for my weight of 170lbs riding a mix of bitumen and bumpy off road ?

(No, I ain't racin' along, just seeking the best balance of speed and control....and reckon the info must be more refined than experimentation.)

Take up the challenge Ye Lovers of all that is TTR ! Lets nail this front fork settings sucker.

OK... well there is no front fork setting as such... The bike comes

from the factory sprung for a 150lb rider... The only way that one setting suits all

is if all riders are the same weight...If you can't get the sags right by useing no more

than 70mm of spring pre load on the front then the springs are not right for your weight

same on the rear with no more than 20mm of pre-load on the spring...

Don't know what the forks springs are rated at... But the rear is 4.2kg/mm

There's your answer to the above post - loose 20 lb

biggrin

Saw a Big Guy but short, with a  jacked up TTR? I mentioned lowering links to him but he said he had no problem?? I found out why when he rode off, the back end nearly bottomed out.

Take a look at Race Tech's site:
http://racetech.com/VehicleSearch#genre=1&brand=Yamaha&model=TT-R250&year=

The spring rate calculator estimates what spring rate you should be using based on your weight and some info about your riding style. For me it suggests the .46kg/mm spring, based on my 175lb weight instead of the .42kg/mm stocker.

Now, I'm not sure how applicable this is to you as your forks might be totally different than my North American model (KYB 43C forks).
