Hi. i have yamaha dt125 1997. My rear wheel is in very bad shape, missing a lot of spokes. I was wondering what is the size of the hub, axle and the rim i need and is their a straight fit from some other bike/model. I thing my rim is 1.85x18, but dont know the size of the hub and axle. Im new with motors so excuse me for the dumb questions and sorry if i have broke some rules. Thank you in advance!
