Ditch your soft, clapped-out stock tubes and transform your front-end tracking with the premium NCY Performance Front Fork Assembly. Engineered specifically for Yamaha Jog architectures and matching 139QMB platform variants, these high-performance stanchions feature sports-tuned internal damping rates that dramatically diminish nose-dive under heavy braking. Finished in a high-gloss midnight black coating, this complete leg set stabilizes your tracking through high-speed turns — ensuring a crisp, confidence-inspiring ride on both street commutes and race setups.

Advanced Suspension Features

  • Sports Damping Optimization: Calibrated to deliver a stiffer, more predictable spring and rebound rate than mushy factory originals — providing better tire contact and road feedback.
  • Flawless 26mm Tube Profile: Precision ground to a 26mm outer stanchion diameter, sliding perfectly into compatible stock or aftermarket triple trees.
  • Disc Brake Ready Geometry: Features integrated structural mounting tabs cast directly into the lower leg to support standard hydraulic disc brake calipers.
  • Complete Setup Kit: Ships as a matched pair (left and right legs) and includes two premium stainless steel hose/line clamps for a professional garage install.

Comprehensive Fitment & Model Guide

These forks are engineered strictly for 10mm front axle pins and front hydraulic disc brake configurations. Please check your exact model below:
