is there a way I can identify what torsion spring I have ? I can not see any numbers on them any where. they were supposed to be from a nytro mtx . I got them wanting to put them on my xtx but I'm thinking they are going to be too stiff for me . the spring dia is 0.4687

thank you
 

Go to "Yamaha SPorts Plaze.com and go into the parts catologue . Look up your machine find your torsion springs listing part number and there should be a rating of the spring itself.
Eg. 1200nm or 1500nm. That kinda number.
The higher the number the stiffer they are.
THEN go back and do same thing for year of the mtx . And see how close they are number wise.
My '13 xtx stock torsion spring is 1200nm
