Frequently Asked Questions

1. What is a Mio Raw Camshaft?

It is an unfinished camshaft (mentah) designed for Yamaha racing modifications, allowing machinists and tuners to grind it according to specific racing needs.

2. Why choose a Raw Camshaft instead of a finished one?

A raw camshaft gives flexibility for custom racing setups, especially for different bore sizes, valve dimensions, and competition requirements.

3. Can it be used for everyday street riding?

It is mainly designed for racing applications. For daily use, standard or mild racing camshafts are recommended.
