Springer fork Yamaha XJR1200 custom

     6 min read

    This is truly the one of a kind custom motorcycle that you just don’t see everyday. The base donor is an old Yamaha XJR1200. The builder, Ambivalence Works, told Webike Magazine a story of how he built this monster bike.

    Ambivalence works: I’m an amateur at customizing and maintenance motorcycles, but I do as much as I can, from welding to painting, by myself. I go by Ambivalence Works, but neither am I a custom bike shop or a professional. I just build this bike out of my company’s office. I first mock up the 74 Springer forks by tossing it in Photoshop, and chose this bike because it was unpopular and inexpensive. I bought the XJR from a friend, and the first thing I did was to see if I could install Springer forks.

    I did as much of the work as I could by myself, but due to lack of knowledge, I had to ask a friend (a true professional) to re-torque the stem shaft of the springer and weld the tank. It took me about 7 months to build the bike, mainly working on it after work and on Saturdays.

    I used a 74 Springer forks picture to mock it up with my favorite cafe racer, scrambler, chopper, bobber, and old school style motorcycles to create a unique and cool bike that doesn’t fit into any category. I was conscious of the overall design balance and lines. I tried to make the body as small as possible to make the engine look bigger, the engine juts out from the frame when the engine guard and steps are omitted.

    It has a very aggressive riding position. The performance is surprisingly good even with the 74 Springer suspension. The tires are massive, so it will be hard to turn the bike around if you don’t get the hang of it, but once you get used to it, it will be fine. I even took it to twisties and it was great.
