  • Front Forks Questions.

    Hi everyone. Got a question for the experts. I知 going to chop my JZ front forks down like the 4mini low style and put on J1 boots. (Like all the bikes on my Instagram feed). Question is: is the thread 33x1? I think Z50Jack identified the thread in one of his posts years ago. I think that was it? I知 going to buy a die.

        Thanks Jaimie, I reckon 34x1 should be ok?

          When you say, chop, what kind of length were you looking to cut them back too?

          I suspect our instagram feeds may have a lot in common......

            I have fork boots here that suit jz fork legs without tapping a thread. I'll sell them if you're interested

              Thanks for the offer Matty, but if I知 not going to cut them, I値l stick to the JZ boots. Much cooler! Haha

                To answer Magilla, I reckon I値l chop off around 40-50mm. I値l be sure to measure twice and cut once. The inserts I got are -5cm cheapies.

                  40 or 50 will be a fair chop on a JZ. I'm looking to do something similar, but with a Chaly. I thought I'd try using a set of shorter front forks and then combine them with shorter inserts.

                  I really may have overdone it though.....I've ordered 30mm short front forks and 55mm short front legs.

                  I can see me ending up with a motor sitting on the ground.

                    8492275D-F2B7-4738-A160-EF293CE694C1.jpeg I don稚 think I致e ever seen a completed picture of this bike (see attached) and I reckon it痴 for the same reason, too much cut out of front forks. The exhaust is touching the ground -as you can see. I tried a few years ago with short forks and failed. So I reckon my way to go this time is scale up a picture off the net of one that has worked and take measurents off the picture.
