Randy from Philippines has prepared a great Y125ZR for drag races there. The colour choices of overall red makes this bikes looks mean and intimidating by its competitor.

The tuning of this bike are massive as it includes YYPang exhaust pipe, VForce3 reed valve system, alloy wheels along with very low profile and narrow tyre to cut the friction to down minimum.
