**There may be changes in product specifications due to the manufacturer's reasons..
The ZEPHYR1100 ST-1 camshaft has been requested by many customers since it was discontinued.
The camshaft is an important part that determines the engine characteristics.Please feel the feeling of the engine created by Yoshimura.
[What is Yoshimura's camshaft?]
■Unique cam profile settings
Yoshimura's camshafts are designed by our own know-how of cam profile.The design of the profile begins with the knowledge of the standard engine specifications.The profile characteristics of Yoshimura camshafts are determined based on the assumed engine speed and characteristics to be used.The next step is to express the determined profile characteristics in numerical values.
From form to number......Yoshimura's years of expertise have led to a unique profile.
A prototype camshaft with the profile created in this way is installed in the engine and checked to see if it actually has the characteristics as expected.If the expected characteristics are not obtained, the design is redone from the beginning.Yoshimura's original cam profile is derived after the repetition of this series of work.
■Integrated production control
Yoshimura's machined camshafts are manufactured under an integrated production control that includes the centering of the camshaft material.The camshaft material that reproduces the profile is also carefully selected and machined from scratch in our company.
This manufacturer avoids applying heat to a part of the product will damage the distortion, deformation and strength of the camshaft itself.In order to make the camshaft hard enough for the engine, the best heat treatment is selected from various methods and applied.
Unique cam profile design + consistent management of production.This is Yoshimura's commitment to the camshaft.
The cam specifications are derived from the design values of the camshaft.Due to the manufacturing process, there is a slight variation in each lot.
The ST-1M can be installed by bolt-on, but if you need more accurate timing, it is recommended to re-set the valve timing for each vehicle.
