ZERO Engineering Rigid Gooseneck Frame Kits are made in Japan rigid frame specifically made for ZERO Engineering Type 5 and Type 6 production bikes has been pursuing "rideability" and "durability". "Flexibility" is important in order to keep comfortable ride especially in rigid frame which don't have suspension to absorb shocks. Instead of suspension, frame itself flexes to absorb various stresses while riding. R&D of ZERO Engineering had repeatedly tried various trial and error in order to give the flexibility.
Motorcycle frames in general are built by using seam welded pipes, but ZERO Engineering frames are built by 4 different diameter pipes comprised of seamless by carbon steel. While balancing sturdiness and flexibility, also keeping high durability.
Although using high quality pipe, welded areas become hardened, so one of the example of down tube on our frame has a long pipe as possible from stem head to rear axle.
Also, instead of having a straight seat post, using S-Bent seat post in order to give stability and persistency even it's cost more. Another characteristic is "Gooseneck". Orthodox technique of chopper production is the gooseneck which pushes out the head pipe forward and curving upper end of the down tube to enhance "low & long".
The real "ZERO Style" is embodied by adopting the goose neck which is motorcycle builder, Shinya Kimura signature design.
